SUBJECT: Summer 2001 Huntington Beach Shoreline Contamination Investigation
NO RECOMMENDATION—information Item Only
The principal investigators and peer review panel representatives will present their initial
findings from the Summer 2001 Huntington Beach Shoreline Contamination Investigation.
SUMMARY
In November 2000 UCI researchers suggested a hypothesis that the Sanitation District's treated
wastewater discharge could be a source of bacteria contributing to the contamination problems
along Huntington Beach. OCSD,from June through October 2001, conducted a large multi-
faceted study of the coastal waters off Huntington Beach and Newport Beach to test this plume
hypothesis. The study was performed to evaluate whether the District's treated wastewater,
discharged 4.2 miles offshore in 200 feet of water,was being transported to shore and causing
the elevated levels of bacteria seen along the Huntington Beach shoreline. The study was
performed by a team of OCSD staff and marine scientists associated with several federal
agencies and academic institutions, including United States Geological Survey, University of
Southern California, Scripps Institute of Oceanography, and the U. S. Naval Postgraduate
School.
OFFSHORE INVESTIGATION:
An independent peer review panel of comprised of oceanographers and microbiologists was
convened jointly by the University of Southern California Sea Grant Program and University of
California Marine Science Institute to critique the work of the study team. The peer review panel
met during the week of April 23 to begin its review of the study results. On April 24 and 25,
2002, the panel members met with the principal investigators involved in the ocean studies to
review the work effort and data analysis.
On May 15. 2002, representatives of the team of principal investigators who conducted the
ocean studies and the peer review panel who are reviewing the work will present to the Board at
this meeting a summary of their findings to date.
ONSHORE INVESTIGATION:
In addition to the offshore Investigation, the District's Source Control Division conducted a
complementary onshore investigation. This work was performed to identify possible onshore
sources that could be contributing to high surfzone bacteria concentrations. Staff members of
the DistricPs Source Control Division who performed the Investigation will also present a '
summary of findings contained in the recently released District report, Huntington Beach
Shoreline Investigation, Phase IN, Onshore Investigation, Final Report July— October 2001.

The Orange County Business Council (Business Council/OCBC), an
organization dedicated to Orange County's economic vitality and quality of
a life, has been very engaged on behalf of Orange County's business
VI!¢GWEH4Y, community on the District's activities relative to ocean water quality and,
specifically, the process of updating the District's strategic plan and
determining appropriate levels of treatment for the future. The Business
"¢GWaNM. Council's interest in these proceedings is two-fold: 1) protection of our
vmuvao)QCTs
ji�e� coastal resources, which are key to our countywide economic prosperity and
quality of fife; and 2) financial and operational impacts upon our member
company businesses and others in the county as a result of your impending
decisions. In this regard, the Business Council wishes to offer the following
comments and requests.
moaxvoaaRevnvwrr
n:m,Iv 1. Coastal protection. The Business Council believes that Orange
County's beaches must be protected. It is simply unacceptable for
F\FGRAS},AFF Orange County residents and visitors to the county to witness beach
raeaonnaao postings and beach closures due to bacterial contamination in the surf
zone. In our view, a deliberative process honoring the principles of
cost-effectiveness; a demonstrated nexus between selected forms of
weucNTNM
lwJe n,mlc treatment and desired results; and common sense, will lead to this
VI(EMBWFn[ protection for our valued coastal resources.
IXVEt'R,PPWIIQ`S
M"a°""" 2. Disinfection. In light of the above, the Business Council supports the
`,RESID,.. District's short-term proposal to disinfect the sewage effluent. This
x " interim measure will ensure that discharged sewage is not responsible
for bacterial contamination in the surf zone. Moreover, a reasonable
test period for this process will aid our community's collective efforts to
determine the source or sources of pollution leading to beach postings.
The Business Council believes that disinfection should commence as
soon as possible.

3. Treatment selection and cost. The Orange County Sanitation District
must be able to demonstrate a nexus between selected levels or forms
of treatment and protection of our ocean water quality. If higher levels
of treatment are warranted to protect ocean water quality, they must be
implemented and we must find ways to pay for them. Yet, it is only
reasonable to consider cost-effectiveness as well if alternatives are
equal in effectiveness for protecting ocean water quality. Required
changes in business operations and/or increases in costs to business
must be justifiable on the basis of determinable results— in this case, a
cleaner shoreline. Orange County residents and business owners must
not find themselves in the position of paying higher fees for higher
levels of treatment that fail to remedy the sources of coastal pollution.
Additionally, the Business Council believes that the Sanitation District
must be willing to apply its own reserves or a portion thereof toward
increased costs of higher levels of treatment, if those are warranted.
4. Long-term considerations. The Business Council recommends that
regardless of the Board's final decision in November of this year on the
301(h) waiver, the District anticipate the longer-term need to move
toward secondary treatment. The Sanitation District and Orange
County's tourism industry are suffering due to the beach postings as
well as the perception, correct or not, that the District's effluent is the
source of the problem. Ultimately, both of these factors have the
potential to adversely affect our county's economy.
The Orange County Business Council has a strong, ongoing interest in this
issue and in your upcoming decisions. We appreciate the opportunities for
engagement that the District has provided to the business community and to
the public at large, and request that you continue to engage us in your
decision-making processes going forward.
Thank you for your consideration.
Sincerely,

RE: OCSD Science, Regulation,Treatment and Disposal Strategy.
In the past,Blake Anderson characterized me as the District's most ardent cheerleader, as
well as its strongest critic. As Chief Scientist in late 1996, 1 was tasked to summarize the
preliminary findings in the now infamous Memo, "The 20-Meter Coliform Study"(for
details see my Eckemoad letter of August 22, 2001). 1 considered it my honor and duty
to provide an expert opinion,based on thirty years experience in marine pollution issues,
of the findings and their implication for future treatment and disposal. My analysis was
concurred in by our Oceanographer(Dr. Michael Rozengurt)and has since received
support of other professional scientists. The first response I received was"a good talking
to" by the TSD Head and ECM Division manager. They strongly argued the memo was
pure speculation and lacking in supporting evidence. This was followed by other
personal restrictions totally unbecoming a public agency. Since then over$10,000,000
has been spent on studies partially vindicating my expert opinion as additional means of
shoreward transport were documented. I now believe that I was rather prescient in my
predictions. Nevertheless, I was treated much like the good doctor in Henrik Ibsen's
political drama, "An Enemy of the People,"as management tried to kill the messenger
rather than consider the message. I was not unique in suffering this science-bashing
approach-the rest are also history. (A recent and relevant example involves the protocol
for the Peer Review Panel, the findings of which most of us will hear for the first time
tonight. I was neither invited nor allowed to attend and observe the meetings held April
23-26 at USC, although the District was given two slots for staff. Were all the key
questions asked and answered honestly? Maybe tonight we will have the first hints?)
At that time in 1997,the District was engaged in discussion with the RWQCB over the
conflict between Santa Ana Basin Plan and State Ocean Plan Bacterial Standards. The
OCSD discharge was likely in "technical violation"of an additional Basin Plan rule that
Bacterial Standards be met throughout the water column, not just in nearshore waters.
Monthly water quality results clearly demonstrated this contamination in the vicinity of
the drifting, subthermocline plume. For years Annual Monitoring Reports routinely
stated "the discharge seldom(if ever)reaches the shoreline". At that time, and now still,
monthly lab reports opined that rainfall runoff or dry weather urban flows caused most of
the occasional shore"exceedences". So what has changed? The RWQCB later voted to
change the Basin plan to conform to the State Ocean Plan. I believe this vote was an
"opportunity lost,"especially after they later(with EPA) approved the 301(h) waiver and
accepted a reduced shoreline bacterial monitoring and reporting protocol in 1998. An El
Nino (1998) was followed by La Nina(1999). This event reduced thermocline strength
exacerbated water column stability and fed the"perfect swarm of bacteria"that brought
extensive closures to the beaches that summer. No other source has been found that
accounts for such widespread contamination. I presented urgent calls to action to the
Districts in August and September of 1999. 1 believe the real opportunity was lost?
When I arrived as Compliance Division Manager in 1989,the District's wastewater
discharge was 250MGD, having grown steadily from 170MGD in 1974. At that time I
was a strong Waiver supporter for pipeline disposal into deep,rapidly mixed and well
flushed ocean waters with seasonal themocline"capping"during maximal summer
beach usage. By 1995, 1 found it more difficult to attribute all shoreline bacterial
exceedences solely to rainfall and urban runoff. This situation was exacerbated when the
State's new AB411 Enrerococcus Standards began to be enforced in summer of 1998,
and more widespread patterns of contamination became apparent. In combination with
high concentrations of total and fecal contamination, AB411 led to the widespread
closure of Huntington Beach in summer of 1999. These findings only strengthened my
1996 opinion that it was time to consider further treatment and/or disinfection measures
to assure continued public health protection throughout the year. I wrote two letters
expressing this concern and asking for immediate action. Such a concerted action on my
"speculation"might have alleviated the pain and lost trust the District has since suffered
from OOG,several City Councils,other political leaders,and the local, statewide and
national news sources. Why was nothing done in 1996?
As the Compliance Division Manager from 1989— 1995,my primary duty was to lead
the ocean investigations and assure compliance follow-up and reporting to EPA and the
RWQCB. At that time there was awareness of but little thought given to measuring such
esoteric processes as upwelling, internal waves,or even urban flows. The sharp
differences between normal, El Nino and La Nina oceanographic conditions only came
on the outfall radar in the past decade. It was not until,as Chief Scientist,I wrote the
"20-Meter Study"that I became aware of the promise to the RWQCB that a disinfection
safeguard was included in the 1972 outfall design,because of engineers'predictions of
plume surfacing during thermocline breakdown in winter. We now know from satellite
photos of SST(sea surface temperature)that such breakdown can often occur in spring,
fall and summer as well. By the time my 1996 memo was written,the District had
already demolished the old chlorination station, leaving in its place a promise to research
newer, safer disinfection protocols for the future. At that time there was the unwarranted
complacency they would never be needed. And now we have the recent OCSD Board fire
drill committing millions to aBand-Aid-approach. Is this how to do the public's business?
I propose that you vote tonight. "DO US A FAVOR,GET RID OF THE WAIVER."
TTy�hi\ern I predict you will leave all of these aforementioned problems behind the District.

Dear Bob,
Subject: Phase III Final Report of OCSD On-Shore Investigation
I have had an opportunity to briefly review your Huntington Beach Shoreline
Contamination Investigation—Phase ll- Onshore Investigation Final Report. We have
begun to compile the issues that fall within our jurisdiction and have already scheduled
a meeting with the Regional Water Quality Control Board staff tomorrow, in order to
begin an action plan to carry out the appropriate recommendations in your report.
Last summer, you shared with us that you were well underway with this onshore
investigation and asked that we provide any information that would help facilitate your
study. I provided points of information in my August 20, 2001, letter to you. Since we
were not given a draft of the final report until its formal release on April 19. 2002, 1 will
provide our city's comments here.
Pa e EST The Huntington Beach Treatment Plant discussed in the report has not
existed for 50 years. I would have expected a much stronger statement than merely
concluding, "None of the information reviewed leads (you) to believe there is a potential
for bacteria contribution from the abandoned plant..."
Pacie E : At your August 15, 2001, press conference, to unveil the preliminary
onshore investigation findings, I made a formal presentation of all the work Huntington
Beach has underway to actively address urban runoff issues. A major element of this
work is the installation of clarifier units to capture debris from 12 storm drains, including
the ones mentioned in your report. This work is being done under the auspices of the
California Water Resources Control Board and the Santa Ana Regional Water Quality
Control Board; but, neither your discussions nor your recommendations make any
mention of this effort.
Pace ES8: The recommendations with regard to the outdoor beach showers and
restrooms are noted; however, again, your source control staffs discussions with City
staff certainly should have revealed that all our beach restrooms are being completely
replaced under two multi-million dollar contracts. Phase I is nearing completion while
Mr. Robert P. Ghirelli
Phase III Final Report
May 15, 2002
Page Two
Phase II is to be under construction this fall. It would seem relevant that this would have
been mentioned in the report, keeping in mind that the facilities around the pier are some 10
thousand feet away from what has been regarded as the chronic "hot spot" in the vicinity of
the AES plant (Station 9 North).
Page 25: No recommendations are given with regard to the findings from the AES outfall dye
tests (Task 3).
Page 42: It should have been clarified that the Adams Pump Station located at the head of
the Huntington Beach Channel is owned, operated and maintained by the County of Orange.
Page 27: No recommendations are given with regard to the findings from the groundwater
elevation studies (Task 6).
Page 44: No recommendations are given with regard to the various pump station and
channel diversion installations (Task 7).
Page 48: While our drainage interceptor projects now funded and under design do not intend
to provide diversions to the sanitary sewer system, your discussions and recommendations
should have taken our work into account, as it will help address your observations. (See our
comments above regarding Page ES8.)
Page 49: The recommended sewer line testing, including conductivity monitoring and
sampling in the vicinity of 1 P and 18s Streets should have been clarified to refer to Newport
Beach.
Page 59: Under Task 12, the report has deferred geological review until such time as there is
"...substantial justification to conduct a further investigation." In contrast to this statement, it
seems relevant to reiterate the findings, concerns and recommendations made by Komex in
its November 2000 Final Report. This was a product of our agencies' cooperative
investigations after the summer of 1999, and issues raised by Komex as needing further
study are glaringly absent.
Specifically, with regard to OCSD Plant#2, Komex commented that"although this site had
already been investigated...(it)focused primarily on the marine outfall and sewage collection
infrastructure. Detailed investigation of on-site piping and related structures had not been
carried out and was considered necessary." Of further concern, Komex found particularly
elevated nitrate concentrations at the southeast comer of OCSD Plant#2 and specifically
recommended that there needs to be a thorough groundwater investigation to rule out
wastewater seepage from the OCSD facilities.
Mr. Robert P. Ghirelli
Phase III Final Report
May15, 2002
Page Three
I submitted these concerns to you in an August 20, 2001, letter. You responded on
September 25, 2001, that further groundwater testing would be done with dewatering related
to an impending project and we would be informed of the results at that time; I never received
any further information. If such information is now available, I would request that you retain
Komex to corroborate your test results and eliminate the major unanswered questions that
were outside Komex' original scope of work.
Paces 63 through 65: It should have been clarified that the 21-inch sewer line in question is
neither owned by nor is it the responsibility of the City of Huntington Beach.
Page 67: The findings should have clearly stated the correct ownership of the 21-inch sewer
rather than imply that it is a City of Huntington Beach responsibility.
Page 70: Comments on the findings for Task 14 on the Huntington Beach Treatment Plant
were discussed above with regard to Page EST
Pages 71 through 76: The constructive comments with regard to the downtown Huntington
Beach storm drain runoff systems are noted and, as mentioned above, we are actively
addressing the appropriate corrective actions. The statement on Page 75, that the City staff
made "...no speck commitments...to address most of the concerns pointed out by Source
Control staff" could mislead a reader to completely and inaccurately conclude that the City is
ignoring the issues. Again, it must be recognized that these facilities are a minimum of 10
thousand feet away from the recognized "hot spot" at Station 9 North.
Page 77: It would have seemed pertinent for the report to state why the OCSD sewer lines
running under the Santa Ana River were not investigated as part of Task 16.

Dr. Cudaback has studied inner-shelf dynamics and transport processes for the past three
years. For the last two years, she has analyzed physical data from the PISCO project,a
consortium of researchers from three west-coast universities, at UCSB. The project is
studying the effects of coastal physical processes on the transport and settlement of larval
fish and invertebrates.
The UCSB branch of PISCO is concerned with species distributions and range boundaries
around the Santa Barbara Channel. The physical oceanographic aspect of this study is built
around moored instrumentation over the inner shelf, measuring currents and temperatures
to understand along-shelf and cross-shelf transport. The processes under study and the
techniques used are quite similar to those in Phase III of the Huntington Beach
Contamination Study.

Patricia (Trish) Holden is an Assistant Professor of Environmental Microbiology in the Bran
School of Environmental Science & Management at the University of California, Santa
Barbara. At the Bran School, Dr. Holden teaches courses in Environmental Microbiology,
Microbiology for Engineers, Bioremediation, and Environmental Biotechnology: Science &
Policy. Her research program is along two lines. First, she studies bacteria in the vadose
zone, focusing on bacterial ecology and factors that influence natural bioattenuation of
petroleum hydrocarbons. Her lab is currently involved in a collaborative effort to understand
how resources (C and N) and stress (water and temperature) influence bacterial community
structure and function along a depth gradient (0 - 4 m) in a California grassland. This
project is also towards understanding the occurrence of bacterial biofilms in the vadose
zone. Dr. Holden's interest in biofilms in dry systems, i.e. "unsaturated biofilms", includes
understanding the production, chemistry and physics of the exopolymer matrix surrounding
bacteria and how these attributes affect biodegradation of low solubility hydrocarbons (e.g.
hexadecane). Microscale processes of colonization and inter-colony communication in the
vadose zone are longer term interests with research projects currently underway.
Holden's lab also studies the application of DNA fingerprinting (T-RFLP) to understanding
the presence of human sewage in coastal creeks, lagoons and estuaries along the south
coast, California. Recent studies in Santa Barbara indicate that historically contaminated
creek sites harbor similar bacterial communities, that creek bacterial communities are
related to urbanization, and that urban bacterial communities are similar to those found in
sewage.
Research in the Holden lab is funded by the NSF (Microbial Observatories Program, and the
Bioengineering Program), the EPA (Bloavailability and Bioremediation Program, and the
Ecological Indicators of Estuarine Ecosystem Health Program), and the UC Toxic
Substances Research and Teaching Program. Her lab is an active research participant in
the PEEIR, or Pacific Estuarine Ecosystem Indicator Research program funded by EPA and
conducted jointly by UCD and UCSB.

Burton Jones is an oceanographer who focuses on the interaction of physical and biological
processes in the ocean environment. His research includes both open ocean and coastal
processes, including the interaction on mixing processes, nutrient fluxes, phytoplankton
productivity, and ocean optics. These studies incorporate a variety of towed, moored and
profiling sensor systems.
Dr. Jones and his colleagues have been studying the impactof coastal pollution processes
since 1984, during which they have applied and integrated physical, chemical, and optical
measurements to improve our understanding of the interaction between coastal ocean
processes and contaminant release and dispersion in the coastal ocean. Some of the topics
on which these studies have focused include physical and biological processes associated
with sewage outfalls, bottom resuspension of toxic sediments, the impact of stonnwater
runoff on the coastal ocean, and other nonpoint sources of contamination.These studies
have utilized a variety of tools including moored physical/bio-optical moorings, bottom
tripods for bottom boundary processes, towed physical/bio-optical packages for high
resolution spatial mapping, remote sensing tools, tracer studies using both natural and
introduced tracers,and numerical modeling.
Dr. Jones has extensive experience in towed mapping studies. Towyo methodology has
been used for the study of POTW discharge plumes from the Los Angeles County White's
Point Ocean Outfall and from the City of Honolulu Sand Island Outfall. During the study of
the Whites Point outfall we implemented pumped sampling with the towyo for continuous

measurements of nutrients at either fixed depths or from vertical profiles. The towyo
methodology has also been used for the mapping of stonnwater plumes in Santa Monica
Bay. Our experience also includes collaboration with the Woods Hole Seasoar group for
large scale studies of open ocean processes in the Arabian Sea and Sea of Japan. These
measurements include the addition of state-of-the-art spectral optical instrumentation for the
mapping of inherent optical properties. These measurements are important for the
interpretation of remote sensing ocean color data and for in situ mapping of particulate fields
derived from various sources.
In addition to the mapping studies using towyo and seasoar technology, we have also
worked with mooring and bottom tripod data sets to examine the physical dynamics
associated with ocean outfalls. We have deployed a bottom mounted tripod on the Palos
Verdes Shelf for measurement of resuspension and dispersion processes.

John Largier has been on the faculty of Scripps Institution of Oceanography (University of
California) since 1988. His specific research interests are the movement of water near to
the shore and in bays and estuaries, as well as the importance of this water motion to
ecological and environmental issues.
Over 20 years in oceanography, and through experiences in research, teaching and
consulting, Dr Largier has developed an integrated view of the coastal ocean and an active
dialogue with non-academic people and agencies similarly concerned with the health of
coastal waters. He is presently involved in research throughout California and in Chile and
southern Africa, with relevance to issues such as water quality, marine reserves, fisheries,
and the effects of climate change. Last year he was awarded an Aldo Leopold Leadership
Fellowship in recognition of his role in linking science with society.
Largier has recently developed a strong portfolio in coastal water quality activities in
California, in recognition of persistent problems and the existence of important gaps in our
knowledge that can be effectively addressed by research science. He maintains an active
dialogue through the Clean Water Task Force (initiative of mayor of San Diego), the Clean
Beach Advisory Group (advisory group for the state Clean Beach Initiative) and the Center
for the Coastal Environment at Scripps (established to develop research in the
environmental arena). Present water quality research activities include an innovative
CODAR-based coastal observing system addressing Imperial Beach bacterial
contamination, determination of contaminant dispersion patterns in Mission Bay and Bodega
Harbor, and assessment of the rate of exchange of surf zone and ocean waters.

Abstract
The Panel is impressed with the size and completeness of the data set collected in Phase
III of the Huntington Beach Contamination Study.The research is of high quality,and
the analyses are progressing well considering the brief time available to date. The Panel
considers the basic conclusion"We have not yet found a substantial connection between
the coastal ocean processes and bacterial contamination on the beaches" as reasonable
based on the PI's preliminary analyses. However,this conclusion is supported by
temporal and spatial patterns that could be artifacts of the data collection and analysis
methods. The Panel has some specific recommendations to further the analyses.The
scientific work is generally of very high quality and can stand alone.
Introduction
The study objectives, as originally stated in the Huntington Beach Shoreline
Contamination Investigation,Phase III Workplan are: "1)characterize the physical
oceanographic processes involved in possible cross-shelf transport of the wastewater
plume in the vicinity of the AES thermal discharge outfall; 2)determine if there is a
causal link between offshore and surf zone bacteria and related plume constituents;and
3)determine if the conditions during the summer of 2001 are similar to those of 1999 and
other years with unusual surf zone bacteria levels".
The PI's listed several hypothesized processes that could transport bacteria from the
OCSD plume to the shore. For each type of physical process,the scientists asked the
following questions:
1. Does the hypothetical physical process exist?
2. Can this process transport the plume?
3. Can this process account for bacterial contamination on Huntington Beach?
The processes under study are:
a) Subsurface transport
i) internal tides
ii) high frequency internal waves and solitions
iii)upwelling.
b) Surface transport
c)Upwelling into Newport Canyon
d) Sediment transport processes
e)Interactions with the AES outfall and intake pipes
2
Experimental Design
The physical oceanography design was sensible given the time and resources. The study
is on par with other substantial shelf programs,and OCSD deserves credit for funding
this program. The spatial and temporal coverage of this data is generally adequate to
address the study questions. However,the areas in the immediate vicinity of the AES
intake and outfall,and within the AES power plant itself are undersampled,and the Panel
hopes that AES will be more helpful in future studies.
The panel recognizes the difficulty of collecting and analyzing bacterial data,but notes
that the study was limited by the lower spatial and temporal resolution of those data.
While this study well exceeded previous studies in sampling intensity, and the number of
bacterial samples processed by OCSD was extraordinary,the bacterial monitoring data is
still a limitation: monitoring can provide weight of evidence,but cannot provide proof of
a hypothesis,especially when samples are negative for measured parameters. The shore-
based bacterial sampling, at ankle depth, is appropriate for regulatory purposes,but may
not elucidate a connection between bacterial contamination and offshore processes.
Water at ankle depth may be contaminated by suspended particles on the beach(see
recommendations below).
Answers to scientific study questions concerning transport processes
1.Does the hypothetical physical process exist?
Panel supports the PI's conclusions(listed below)except where otherwise noted.
a) Subsurface transport
i) internal tides—yes,but the analysis of the characteristics of internal tides is
incomplete; a spring to neap internal tidal cycle was neither investigated or
documented(see recommendations for further analyses of existing data
below)
ii) high frequency internal waves—this process is undocumented so far;the
investigators assigned lower priority due to time constraints and initial
impressions of the data
iii)upwelling—there is evidence for this process in mean time series data
(upward sloping isotherms). However,there was no differentiation
between the potential sources: wind driven,remotely forced,or modulation
of the internal tide.
b)Surface transport—this process was not highly prioritized, and therefore not
addressed,by the investigators because the plume is almost never detected
at the surface. However, see recommendations under future studies.
c)Upwelling into Newport Canyon—yes,but the data did not demonstrate
upwelling over lip of canyon onto the shelf
3
d) Sediment transport processes—not clear;the investigators claim that the near
bottom shear stress is insufficient to resuspend sediment,but that variable
has not been accurately determined.
e)AES influence—there is insufficient information to date.
2. Can the hypothetical process transport the plume toward the beach?
Again,the Panel supports the PI's conclusions on most points.
a) Subsurface transport
i) internal tides—yes.
ii) high frequency internal waves—unknown.
iii)upwelling—yes;especially in conjunction with an internal tide
b)Surface transport—PIs did not address this;the panel suggests more
investigation of possible onshore transport forced by the sea breeze.
c)Upwelling into Newport Canyon—yes,the shipboard tow-yo data shows this
mechanism.
d) Sediment transport processes—since there is no evidence,the panel cannot
evaluate this as a transport mechanism.
3.Can this process account for bacterial contamination on Huntington Beach?
The PI's conclude that they have "Not yet found a substantial connection between the
coastal ocean processes and bacterial contamination on beach." The PI's support their
conclusion by two pieces of evidence: 1)there is a temporal disconnect between
individual contamination events and times when physical processes are most likely to
drive cross-shelf transport,and 2)there is a spatial disconnect between high bacterial
concentrations near the OCSD outfall and high bacterial concentrations at the beach.The
Panel considers the central conclusion that a substantial connection has not been found as
reasonable based on the PIs preliminary analyses, but has some concerns about the
completeness of the analyses.The panel suggests continuation and extension of the
analyses to more thoroughly document and understand relevant shelf circulation
processes and plume behavior in relation to possible beach contaminations:
Presentation and analysis of temporal relationships:
a)Temporal resolution of bacterial measurements is not sufficient to draw a
definitive conclusion(except during intensive sampling,when the temporal
resolution is marginally adequate). However,the panel recognizes the
intensive effort needed for actual bacterial sampling(see recommendations for
future studies below about sampling a plume proxy).
b)The analysis should be expanded to use all of the bacterial data,instead of just
single day exceedances(see recommendations for further analyses of existing
data below).
4
Presentation and analysis of spatial patterns:
a)The data should be shown as cross shelf section or plan view—3D plots obscure
the spatial relationship of data across the shelf and the interpolation used in
these 3D plots is undocumented.
b)A spatial connection cannot be discarded with the current information—evidence
in support of spatial disconnection is uncertain in at least one event as
presented. However,this does not preclude the possibility of two different
sources/processes: nearshore and offshore.
c) Analysis is preliminary and PI's need to check internal consistency of data (e.g.
compare behavior of temperature/velocity data with that of the plume data;
see recommendations for further analyses of existing data below)
d)Panel recognizes that the analysis is incomplete but data set is good
Discussion of other sources needing further investigation:
The Panel agrees with PIs that OCSD plume is not the only possible source of
contamination on the beach:
a)AES: potential as source, pathway and amplification of bacteria is understudied.
Better cooperation from AES is needed. PIs did as much as they could with
limited resources and inadequate cooperation.
b) SAR and Talbert Marsh: additional potential sources of beach contamination
c)Beach sources: potentiality of local beach sources (e.g., sediments,dogs,birds)
Underlying ambiguity:
There seem to be several definitions of the plume, and the definitions are not
equivalent. The physical plume is identified by a salinity anomaly relative to the T-
S relationships in the ambient water;generally T<12°C and S<33.6 psu.The plume
may also be identified by high concentrations of ammonium,which may be a
passive tracer,or bacteria,which are probably not passive tracers. The study did not
model the flux of the bacteria(incorporating currents and transport,plus kinetics of
die-off)from plume to shore.
Panel Recommendations
Recommendations for further analyses of existing data(before August meeting)
The"plume"needs to be better defined:
Need to relate temp/salinity anomaly,and ammonium data with bacteria counts.
Sensitivity of assays used and methods of measurement need to be addressed.
Re-analyze the beach contamination events in relation to oceanographic processes using
all the bacterial data,instead of just the single day exceedences.
Analyze cross-shelf transport mechanisms on this shelf(using the time series
measurements from the arrays).
-Could also include possible across-shelf flux in the bottom Ekman layer.
5
Analyze the characteristics of the internal tides(e.g., strength, intermittence, spatial and
temporal variability). This data set is ideally suited to help characterize the internal
tide from the slope to the surf zone.
Recommendations for future studies
Explore the transport of buoyant particles by the sea breeze and look for particles at the
surface
Better temporal sampling of a plume proxy(e.g.,ammonium)
Adaptive sampling of the internal tidal bore(including dye study with optical
measurements near the beach)
Circulation modeling including bacterial transport and assessment of diffusion vs.
mortality of bacteria
Repeat intensive bacterial sampling during neap tides to look for beach contamination
events
Attempt to get better cooperation from AES for instrumentation of their plant

Fecal Indicator Bacteria (FIB): Cons
• Natural sources exist (estuarine sediments,
bird droppings, marine vegetation)
• Usually not human pathogens
• Can die-off more rapidly than human
viruses in marine waters
F+ (male-specific) coliphage or
Fecal Indicator Viruses (FIV): Pros
• Present at high concentrations in raw (and
partially treated) sewage
• Can also derive from non-human fecal
matter (e.g., dogs, cats, birds), but should
not be growing in the environment
• Resistance patterns are more similar to
human viruses
F+ (male-specific) coliphage or
Fecal Indicator Viruses (FIV): Cons
• More difficult to assay
• No epidemiological evidence (yet) to link
them to bather illnesses
• Not used to make decisions regarding surf
zone postings and/or closures
• Ecology may not be that of human viruses
F+ (male-specific) coliphage or
Fecal Indicator Viruses (FIV): Cons
• More difficult to assay
• No epidemiological evidence (yet) to link

• Ecology may not be that of human viruses
Question
Is surf zone water quality impairment at
Huntington Beach caused by fecal pollution
from onshore sources (runoff, groundwater,
wetlands) or offshore sources (offshore
discharges of treated wastewater, power
plant cooling water) ?
Answer 1
At the Santa Ana River study site, Fecal
Indicator Bacteria (FEB) appear to be
generated locally. There is no evidence to
suggest that they are coming from offshore.

Answer 2
• Fecal indicator viruses (FIV), on the other
hand, appear to be transported to the Santa
Ana River study site with cold ocean water.
• The cold ocean water also appears to trigger
phytoplankton blooms.
• One possibility is that offshore upwelling of
deeper/colder ocean water brings FIV and
nutrients into the study area.
Implications for Postings &
Closures at Huntington Beach
• The results do not support the idea that FIB
in the surf zone are from the OCSD outfall,
at least for the area around the SAR outlet.
• The results do support the idea that FIB in
the surf zone are from land-based sources of
fecal pollution (storm drains, runoff, marsh
effluent)
Implications of Virus Testing
® The study results suggest that FIV in the
surf zone may be from offshore sources,
possibly the OCSD plume.
• However, the human health significance of
FIV in the surf zone is unknown.
® Under current practice, surf zone posting &
closure decisions are based on FEB
concentrations, not FIV concentrations.
What about recent postings/closures at
6N?
• The Newport Shores storm drain cannot
account for the recent closures/postings at
6N (currently shut off from ocean
exchange)
• Could be caused by ebb flow from
SAR/Talbert Marsh outlets (possible),
groundwater contamination (unlikely), or
OCSD plume (possible)

FROM: Sean Fitzgerald, Client Manager
SUBJECT: Proposition 13 Groundwater Storage Construction Grant Update
DATE: May 10, 2002
TO: Ron Wildennuth, OCWD
Lisa Murphy, OCSD
The Department of Water Resources released today the staff recommendations
regarding funding levels for the Proposition 13 Groundwater Storage Construction Grant
applications. The Groundwater Replenishment System was recommended to receive
$30,000.000
The GWR Project ranked sixth out of the forty-three projects that were submitted and is
one of only twelve that have been recommended for funding. It is the largest single
grant amount included in the initial recommendations, representing over 30% of the
funding appropriated this year for the entire state of California. As a comparison, Kem
County, with a total of four projects, received only $27,006,000, which makes Orange
County the largest recipient county in the state.
Now that the staff recommendation has been secured, Townsend Public Affairs, Inc. will
shift the focus of our advocacy to protecting and possibly increasing this level of funding
throughout the remaining steps in the grant cycle.
First, the Department of Water Resources will hold a public hearing in Sacramento on
May 21`r, from 9:30 AM to 12:30 PM, to receive input from the public. This could be an
opportune time to reemphasize publicly the strengths of this project. Subsequently, the
recommendations go before CALFED, before returning to Director Hannigan's office.
The final decisions, after review by the Governor's office, are expected by mid-June.
Throughout this entire remaining process, we will need to aggressively protect this
$30,000,000. In addition to direct engagement with the Governor's office, we must also
reinforce the GWR Project's strong, unified, bipartisan local base of support within the
Orange County State Senate and Assembly delegations.

"aSatun ,. The Orange County Business Council (Business Council/OCBC), an
F� organization dedicated to Orange County's economic vitality and quality of
na"a,caa life, has been very engaged on behalf of Orange County's business
MCM1J UA. community on the District's activities relative to ocean water quality and,
W1BuC a= specifically, the process of updating the District's strategic plan and
RBeCopni""r¢'°*^M determining appropriate levels of treatment for the future. The Business
AacuummtI, Council's interest in these proceedings is two-fold: 1) protection of our
sv®Nvagrcrs
coastal resources, which are key to our countywide economic prosperity and
"®"wRNM quality of life; and 2) financial and operational impacts upon our member
RIRNF°ICHMMHE company businesses and others in the county as a result of your impending
M Mq as decisions. In this regard, the Business Council wishes to offer the following
"aGN comments and requests.
woRvoRaoere.ovloar
1. Coastal protection. The Business Council believes that Orange
County's beaches must be protected. It is simply unacceptable for
v>mmvv aTNP Orange County residents and visitors to the county to witness beach
vRainFNfEaO postings and beach closures due to bacterial contamination in the surf
M O " zone. In our view, a deliberative process honoring the principles of
Rre"reePre10°"• cost-effectiveness; a demonstrated nexus between selected forms of
YIIRHC NiNRS
loi�ewe,aa treatment and desired results; and common sense, will lead to this
"a"W510 . protection for our valued coastal resources.
DE ROPRGTE
INASIOR RRNRUNS
A° N°"'" 2. Disinfection. In light of the above, the Business Council supports the
WaDistrict's short-term proposal to disinfect the sewage effluent. This
R�maN^ a interim measure will ensure that discharged sewage is not responsible
for bacterial contamination in the surf zone. Moreover, a reasonable
test period for this process will aid our community's collective efforts to
determine the source or sources of pollution leading to beach postings.
The Business Council believes that disinfection should commence as
soon as possible.

3. Treatment selection and cost. The Orange County Sanitation District
must be able to demonstrate a nexus between selected levels or forms
of treatment and protection of our ocean water quality. If higher levels
of treatment are warranted to protect ocean water quality, they must be
implemented and we must find ways to pay for them. Yet, it is only
reasonable to consider cost-effectiveness as well if alternatives are
equal in effectiveness for protecting ocean water quality. Required
changes in business operations and/or increases in costs to business
must be justifiable on the basis of determinable results — in this case, a
cleaner shoreline. Orange County residents and business owners must
not find themselves in the position of paying higher fees for higher
levels of treatment that fail to remedy the sources of coastal pollution.
Additionally, the Business Council believes that the Sanitation District
must be willing to apply its own reserves or a portion thereof toward
increased costs of higher levels of treatment, if those are warranted.
4. Long-term considerations. The Business Council recommends that
regardless of the Board's final decision in November of this year on the
301(h) waiver, the District anticipate the longer-term need to move
toward secondary treatment. The Sanitation District and Orange
County's tourism industry are suffering due to the beach postings as
well as the perception, correct or not, that the District's effluent is the
source of the problem. Ultimately, both of these factors have the
potential to adversely affect our county's economy.
The Orange County Business Council has a strong, ongoing interest in this
issue and in your upcoming decisions. We appreciate the opportunities for
engagement that the District has provided to the business community and to
the public at large, and request that you continue to engage us in your
decision-making processes going forward.
Thank you for your consideration.

MEMORANDUM
TO: Virginia Grebbien, General Manager, OCWD
Blake Anderson, General Manager, OCSD
FROM: Sean Fitzgerald, Client Manager
SUBJECT: Proposition 13 Groundwater Storage Construction Grant Update
DATE: May 10, 2002
TO: Ron Wildennuth, OCWD
Lisa Murphy, OCSD
The Department of Water Resources released today the staff recommendations
regarding funding levels for the Proposition 13 Groundwater Storage Construction Grant
applications. The Groundwater Replenishment System was recommended to receive
$30,000,000.
The GWR Project ranked sixth out of the forty-three projects that were submitted and is
one of only twelve that have been recommended for funding. It is the largest single
grant amount included in the initial recommendations, representing over 30% of the
funding appropriated this year for the entire state of California. As a comparison, Kern
County, with a total of four projects, received only $27,000,000, which makes Orange
County the largest recipient county in the state.
Now that the staff recommendation has been secured, Townsend Public Affairs, Inc. will
shift the focus of our advocacy to protecting and possibly increasing this level of funding
throughout the remaining steps in the grant cycle.
First, the Department of Water Resources will hold a public hearing in Sacramento on
May 21', from 9:30 AM to 12:30 PM,to receive input from the public. This could be an
opportune time to reemphasize publicly the strengths of this project. Subsequently, the
recommendations go before CALFED, before returning to Director Hannigan's office.
The final decisions, after review by the Governor's office, are expected by mid tune.
Throughout this entire remaining process, we will need to aggressively protect this
$30,000,000. In addition to direct engagement with the Governors office, we must also
reinforce the GWR Projects strong, unified, bipartisan local base of support within the
Orange County State Senate and Assembly delegaftons.

Plume Observation Summary
• Plume observed during spring tides
under various flow and stratification
regimes.
• AB411 exceedances observed during
all 6 cruises.
• Plume came nearshore only in Newport
Canyon.
• Observations showed no obvious
connection between the plume and
beach contamination.
Newport Canyon Hypothesis
Conclusions
• Some downcoast flows last long enough
that water near the outfall might reach
Newport Canyon.
• Nearshore current reversals can occur.
• No AB411 exceedance events were
measured while the windows associated
with these events were open.
15
Nearshore Transport Processes
& AES Power Plant
• Is cold sub-thermocline water transported
into surfzone?
— Wave-driven circulation (rip current).
— Internal tide runup (swash).
— Power plant (entrainment & thermal plume).
Internal Tide Hypothesis
• Internal tides generated at the shelf break
transport plume bacteria toward the coast
along a path that remains below the
thermocline.
• Over the inner-shelf, the shoaling of the
internal tides may enhance shoreward
transport.
• Once bacteria reaches 10 - 15 m, other
process bring the material to the beach, such
as:
—Surfwne exchange
—AES oulfall

Conclusion for Cold Events
• Internal tides exist.
• Not usually associated with measured
contamination events on the beach.
• Survey data always showed a break
between offshore and surfzone bacteria.
18
Internal Tide Runup
Cold, sub-thermocline water can swash inshore beyond 10m,and even
cooling the surfzone at times.
But, cross-shore pulses of cold water are not routine inshore 10m, &do
not explain observed temperature changes (Boehm at al).
Further, no correlation between surfzone cool events& observed bacteria
events.

Nearshore Conclusions
• Internal tide cool events can be
detected in surfzone.
• No correlation between nearshore cool
events and beach contamination
events.
• No correlation between nearshore warm
events and beach contamination
events.
20
Summary
• A colossal amount of data was collected
in this study.
• We've seen that a number of the
hypothesized processes do exist in the
coastal ocean.
• Hydrographic surveys that mapped
bacterial concentrations at low levels
always showed a gap between offshore
and surfzone bacteria.
Summary
• Cold events, internal tidal swashing and
Newport Canyon processes were not
associated with AB411 exceedances
on the beach.
• There are other known sources for
bacterial contamination of the beach.
21
Understanding to Date
"We have not yet found a connection
between coastal ocean processes and
bacterial contamination on the
beaches."
Future Work — Existing Data
• Continue examination of present data
sets to confirm our initial findings
• Use this extensive data set to:
— develop better models for plume tracking.
— determine the best location for any
continued ocean monitoring moorings.
22
Future Work — New Studies
• Expand bacterial measurements at the
beach and in nearshore waters.
• Measurement of nearshore circulation
• Employ new technology.
• Examine more land source possibilities.

Chair's Report
Board Meeting of
May 15'", 2002
GOOD EVENING. A SPECIAL WELCOME TO OUR VISITING PANEL
OF EXPERTS AND TO THE MEMBERS OF THE PUBLIC WHO MAY
BE HERE FOR THE FIRST TIME.
1. TONIGHT IS VERY IMPORTANT FOR TWO REASONS:
FIRST, THE LONG-AWAITED SCIENCE REGARDING OUR OCEAN
DISCHARGE WILL BE PRESENTED BY THE RESEARCHERS AND
BY AN INDEPENDENT PEER REVIEW PANEL OF EXPERTS. THESE
RESEARCHERS AND EXPERTS WHO HAVE LOOKED AT THE
DATA REPRESENT SOME OF THE MOST RESPECTED AND WELL-
KNOWN OCEANOGRAPHIC INSTITUTIONS IN THE COUNTRY.
SECOND, TONIGHT BEGINS THE DIALOGUE THAT THIS BOARD
MUST UNDERTAKE REGARDING A CRITICAL PUBLIC POLICY
DECISION, NAMELY:
"WHAT LEVEL OF WASTEWATER TREATMENT
TECHNOLOGY SHOULD THE SANITATION DISTRICT BUILD
AND OPERATE IN THE FUTURE THAT WILL ADEQUATELY
PROTECT PUBLIC HEALTH AND THE ENVIRONMENT?"
V
BEGINNING TONIGHT AND CONTINUING THROUGH NEXT
MONTH, THIS BOARD WILL HEAR ABOUT:
1. THE SCIENCE: WHAT DID LAST SUMMER'S $5
MILLION OCEAN STUDIES TELL US?
2. THE TECHNOLOGY: WHAT TREATMENT PROCESS
ALTERNATIVES ARE AVAILABLE FOR OUR
CONSIDERATION?
3. THE FINANCES: WHAT ARE THE COST AND USER FEE
IMPLICATIONS OF THOSE ALTERNATIVES?
4. THE REGULATIONS: WHAT ARE THE FEDERAL AND
STATE RULES THAT GOVERN US? AND, FINALLY,
5. THE PUBLIC: WHAT HAVE WE HEARD FROM THE
PUBLIC IN THE FORM OF OPINION POLLS, LETTERS,
E-MAILS AND PHONE CALLS?
TONIGHT, WE WILL HEAR FROM THE SCIENTISTS. THEY WILL
TELL US ABOUT THE RESEARCH WORK THAT WAS CONDUCTED
LAST SUMMER.
2. 1 NEED TO MAKE ONE ANNOUNCEMENT REGARDING NEXT
WEEK'S REGULARLY SCHEDULED BOARD MEETING: THIS IS A
TIME CHANGE. THE MEETING WILL START A HALF HOUR
EARLY AT 6:30. WE WILL START WITH A CLOSED SESSION THAT
SHOULD LAST NO LONGER THAN 30 MINUTES. THEN WE'LL
OPEN THE MEETING UP TO REGULAR BUSINESS, PROBABLY AT
7:00 AS WE NORMALLY DO.
