Benthos — The community of organisms, such as sea stars, worms and shrimp, which live on, in, or near the seabed, also know as the benthic zone. Biochemical Oxygen Demand (BOD)—The amount of oxygen used when organic matter undergoes decomposition by microorganisms. Testing for BOD is done to assess the amount of organic matter in water. Biosolids — Biosolids are nutrient rich organic and highly treated solid materials produced by the wastewater treatment process. This high-quality product can be recycled as a soil amendment on farm land or further processed as an earth-like product for commercial and home gardens to improve and maintain fertile soil and stimulate plant growth. Capital Improvement Program (CIP) — Projects for repair, rehabilitation, and replacement of assets. Also includes treatment improvements, additional capacity, and projects for the support facilities. Coliform bacteria—A group of bacteria found in the intestines of humans and other animals, but also occasionally found elsewhere used as indicators of sewage pollution. E. coli are the most common bacteria in wastewater. Collections system — In wastewater, it is the system of typically underground pipes that receive and convey sanitary wastewater or storm water. Glossary of Terms and Abbreviations Certificate of Participation (COP) -A type of financing where an investor purchases a share of the lease revenues of a program rather than the bond being secured by those revenues. Contaminants of Potential Concern (CPC) - Pharmaceuticals, hormones, and other organic wastewater contaminants. Dilution to Threshold (D!f) - the dilution at which the majority of the people detect the odor becomes the D(f for that air sample. Greenhouse gases - In the order of relative abundance water vapor, carbon dioxide, methane, nitrous oxide, and ozone gases that are considered the cause of global warming ("greenhouse effect"). Groundwater Replenishment (GWR) System - A joint water reclamation project that proactively responds to Southern California's current and future water needs. This joint project between the Orange County Water District and the Orange County Sanitation District provides 70 million gallons a day of drinking quality water to replenish the local groundwater supply. Levels of Service (LOS)-Goals to support environmental and public expectations for performance. NOMA- N-Nitrosodimethylamine is an N-nitrosoamine suspected cancer-causing agent. It has been found in the Groundwater Replenishment System process and is eliminated using hydrogen peroxide with extra ultra-violet treatment. National Biosolids Partnership (NBP) - An alliance of the National Association of Clean Water Agencies (NACWA) and Water Environment Federation (WEF), with advisory support from the U.S. Environmental Protection Agency (EPA). NBP is committed to developing and advancing environmentally sound and sustainable biosolids management practices that go beyond regulatory compliance and promote public participation in order to enhance the credibility of local agency biosolids programs and improved communications that lead to public acceptance. Plume-A visible or measurable concentration of discharge from a stationary source or fixed facility. Publicly-owned Treatment Works (POTW)- Municipal wastewater treatment plant. Santa Ana River Interceptor (SARI) Line - A regional brine line designed to convey 30 million gallons per day (MGD) of non-reclaimable wastewater from the upper Santa Ana River basin to the ocean for disposal, after treatment. Sanitary sewer - Separate sewer systems specifically for the carrying of domestic and industrial wastewater. Combined sewers carry both wastewater and urban run-off. South Coast Air Quality Management District (SCAQMD) - Regional regulatory agency that develops plans and regulations designed to achieve public health standards by reducing emissions from business and industry. Secondary treatment - Biological wastewater treatment, particularly the activated-sludge process, where bacteria and other microorganisms consume dissolved nutrients in wastewater. Sludge - Untreated solid material created by the treatment of wastewater. Total suspended solids (TSS)-The amount of solids floating and in suspension in wastewater. Glossary of Terms and Abbreviations Trickling filter — A biological secondary treatment process in which bacteria and other microorganisms, growing as slime on the surface of rocks or plastic media, consume nutrients in wastewater as it trickles over them. Urban runoff — Water from city streets and domestic properties that carry pollutants into the storm drains, rivers, lakes, and oceans. Wastewater—Any water that enters the sanitary sewer. Watershed —A land area from which water drains to a particular water body. OCSD's service area is in the Santa Ana River Watershed.
