7 EXECUTIVE SUMMARY The 2015 Annual Ocean, Harbor and Bay Water Quality Report provides an updated analysis of bacteriological water quality data for Orange County s recreational waters and includes data on sewage spills and related ocean, harbor and bay water closures. The annual report also describes year-to-year variability and trends representing the 16-year period ( ) that Assembly Bill 411 (AB 411) Ocean Water-Contact Sports Standards for bacteriological water quality have been in place. In addition, the annual report incorporates historical sewage spill and associated ocean, harbor and bay water closure information during the most recent 29-year period from Major findings of the 2015 Annual Ocean, Harbor and Bay Water Quality Report: Sewage Spills and Ocean, Harbor and Bay Water Closures The total number of sewage spills reported to the Ocean Water Protection Program in 2015 was 133, continuing a steady decline and down 67.4% from the peak record of 408 spills set in During 2015, the total number of sewage spills resulting in beach closures (10) remained 53% below the 29-year average of 19 beach closures per year. The total number of Beach Mile Days (BMD s) due to sewage spill closures was 18.9 and is 33% below the 17-year average of 28.2 BMD s from 1999 through Pipeline blockages continue to be responsible for the majority of sewage spills resulting in beach closures. Since 1999, blockages have resulted in 62% of all closures and over half of these blockages (56.5%) were caused by infiltration of roots or deposition of grease. Posted Warnings Due to Bacteriological Standards Violations A new unified regional monitoring plan was implemented at south county beaches at the beginning of the 2015 AB 411 period (April 1 to October 31). The plan requires point zero monitoring at locations where urban runoff physically enters the ocean. First year monitoring results during the AB 411 period showed 20 out of the 28 point zero stations were in 100% compliance with ocean water health standards. See Appendix 6 for additional information about point zero monitoring results. Total Beach Mile Days posted due to bacteriological water quality standards violations during the AB 411 period (April 1 to October 31) were 36.2 which is 90.1% below the record high of 366 recorded in The continuing trend of record lows over the last 3 years is likely due to drought and less runoff impacting the beach. During the summer of 2015, HCA/Environmental Health partnered with Stanford University and Heal the Bay for a Predictive Modeling pilot study. One of the three chosen pilot locations in Southern California was at San Juan Creek in Doheny State Beach. The pilot used a daily computer model to determine if water quality at selected beach locations would exceed state health standards and require posting. Sixty (60) samples were collected during the period to track the accuracy of the daily predictions, also known as nowcasts, and results showed that the model accurately predicted water quality the majority of the time. A continuation of the pilot study is planned. Beach Mile Days at the mouth of the San Gabriel River in Seal Beach have increased over the last 4 years exceeding the last high point recorded in The increase coincides with recent drought years and might be interrelated, however, additional study is required.

11 THE OCEAN WATER PROTECTION PROGRAM As part of the County of Orange Health Care Agency, the Environmental Health Ocean Water Protection Program is responsible for protecting the public from exposure to ocean and bay waters that may be contaminated with sewage or may cause illness along Orange County s 42 miles of open ocean coastline and 70 miles of harbor and bay frontage. Ocean and bay waters used for body-contact recreational activities such as swimming, surfing and diving must meet specific bacteriological water quality standards to be considered safe for such purposes. In 2015, the Health Care Agency (HCA), the Orange County Sanitation District (OCSD), the South Orange County Wastewater Authority (SOCWA) and OC Public Works (OCPW) cooperatively tested the coastal waters in Orange County for bacteria that indicated the possible presence of disease-causing organisms. Staff from HCA s Ocean Water Protection Program, OCSD, SOCWA and OCPW participated in the weekly collection of water samples at 140 ocean, harbor and bay monitoring locations throughout coastal Orange County. Last year, over 8400 ocean, harbor, and bay water samples were collected and approximately 25,273 analyses were performed to determine the results for three indicator bacteria used for compliance purposes (i.e., total coliform, fecal coliform and enterococcus). The Ocean Water Protection Program staff review the bacteriological sample results daily and will issue ocean, harbor and bay water closures, postings and health advisories under the requirements stipulated by the California Health and Safety Code and Title 17 of the California Code of Regulations. When the results of testing indicate that one or more of the AB 411 Ocean Water-Contact Sports Standards have been exceeded, the public is notified, signs are posted at the beach, and the monitoring frequency and locations may increase until the sample results meet established standards and/or the source of the problem is eliminated. In addition, Ocean Water Protection Program staff respond on a 24-hour basis to investigate any reports of sewage or other potential contamination incidents that may affect public health at any of Orange County s ocean, harbor and bay water areas. The Ocean Water Protection Program maintains an Ocean, Harbor and Bay Water Posting and Closure web page, telephone hotline and social media account (Twitter), which provides current information regarding Orange County beach closures, posted warnings and advisories. The telephone hotline and web page are immediately updated and a Twitter message is sent when a change of status occurs at any ocean, harbor or bay water area in Orange County.

12 Ocean Water-Contact Sports Standards Assembly Bill 411 (AB411) In 1998, AB 411 (Wayne) was chaptered into law and added Sections to the California Health and Safety Code. The law authorized the creation of bacteriological ocean water quality standards that are considered protective of public health (California Code of Regulations Sections ). The standards are informally called AB 411 standards and include the following: Required testing of the waters adjacent to all ocean and bay public beaches for total coliforms, fecal coliforms and enterococci bacteria that may indicate the presence of possible disease-causing bacteria, viruses or protozoa. Required maintenance and updates of the Ocean, Harbor and Bay Posting and Closure Hotline. Established single sample standards for total coliforms, fecal coliforms and enterococci bacteria which shall not exceed: Total Coliforms: 10,000 organisms per 100 milliliter sample. Fecal Coliforms: 400 organisms per 100 milliliter sample. Enterococci: 104 organisms per 100 milliliter sample. Fecal Coliform to Total Coliform ratio: >1,000 total coliforms if ratio exceeds 0.1. Established 30-day geometric mean standards (of five weekly samples) for total coliforms, fecal coliforms and enterococci bacteria which shall not exceed: Total Coliforms: 1,000 organisms per 100 milliliter sample. Fecal Coliforms: 200 organisms per 100 milliliter sample. Enterococci: 35 organisms per 100 milliliter sample. When any waters adjacent to a public beach fail to meet any of the standards described above, the local health officer shall post signs on the beach to restrict access to the affected waters. Weekly testing is required from April 1 to October 31 if the following applies: The beach is visited by more than 50,000 people annually. The beach is located in an area adjacent to a storm drain that flows in the summer. In the case of a known release of sewage into ocean or bay waters adjacent to a public beach, the local health officer is required to: Immediately close the affected ocean or bay waters until the source of the sewage is eliminated. Collect bacterial samples from the affected waters. Continue the closure until testing results of water samples meet the established standards.

13 Disease-Causing Microorganisms Contaminated runoff and untreated sewage released into ocean and bay waters may result in swimmer exposure to pathogenic bacteria, viruses or protozoa. These disease-causing microorganisms may be present at or near the sites where discharges enter the water. The following table lists the types of microorganisms and the diseases (or symptoms) they may cause. PATHOGENIC AGENT DISEASE Bacteria Escherichia coli (E. coli) Gastroenteritis Salmonella (not typhi) Gastroenteritis, usually with fever; less commonly septicemia (generalized infection - organisms multiply in the bloodstream) Some strains of Shigella Gastroenteritis, usually with fever Protozoa (Intestinal Parasites) Cryptosporidium Giardia lamblia Diarrhea Cryptosporidiosis Diarrhea Giardiasis Viruses Rotavirus Enteroviruses Norwalk and Norwalk-like viruses Adenovirus Hepatitis A (outbreaks associated with eating shellfish from sewage-contaminated water) Gastroenteritis Respiratory infection, rash, fever, meningitis Gastroenteritis Respiratory infection and gastroenteritis Infectious hepatitis (liver malfunction) The levels of bacteria, viruses and protozoa typically decrease in ocean and bay waters over time due to the following reasons: Die off due to sun (ultraviolet exposure), salt water or age. Predation by other organisms. Dispersion and dilution. Woods Cove at Sunset Laguna Beach 2015 Annual Ocean, Harbor & Bay Water Quality Report - Page 3

14 Indicator Bacteria Testing Methods The detection and enumeration of disease-causing organisms (pathogens) identified with waterborne illness is difficult, time-consuming and costly. Thus, most water quality laboratories are required to test for fecal indicator bacteria (i.e., total coliforms, fecal coliforms and enterococci) as a means to ascertain the likelihood that human pathogens may be present in recreational waters. Fecal indicator bacteria normally occur in the intestines of all warm-blooded animals, are excreted in high numbers in feces, but can also be found in soil and decaying vegetation. Since there is no ideal indicator group, testing is done for more than one indicator. Total coliforms are a broad group of organisms that include fecal coliform bacteria as well as E. coli. The enterococci group has been determined to be a good indicator of water-contact associated gastroenteritis. The methods most commonly used to detect fecal indicator bacteria in water include: Membrane Filtration (MF) Multiple-Tube Fermentation (MTF) Colilert Enterolert All of the methods are culture based, which means that the indicator bacteria present in water must be allowed to grow in order to be detected. Differences between the methods include how the bacteria are detected and counted, how soon the results become known, and cost. Each method has its advantages and disadvantages. Most of the limitations depend on factors such as the other types of constituents in the water and density of bacteria present, and all require at least an 18-hour incubation period. The following is a brief summary of the Membrane Filtration method, the method used by the County of Orange Health Care Agency/Public Health Laboratory, the South Orange County Wastewater Authority Laboratory and the Orange County Sanitation District Labora tory for the analyses of total coliforms, fecal coliforms and enterococci in ocean and bay waters. Detailed descriptions for the Membrane Filtration (MF), Multiple- Tube Fermentation (MTF), Colilert and Enterolert methods are available in the latest edition of Standard Methods for the Examination of Water and Wastewater. Membrane Filtration (MF) The Membrane Filtration method involves filtering water through a porous membrane to concentrate or trap bacteria from the water sample on the filter surface. The membrane filter is placed onto a culture medium designed to encourage the growth of the target indicator. The filter is incubated for hours to allow the bacterial cells to multiply into visible colonies. Theoretically, each bacterial cell (or clump of cells) produces a single colony on the membrane. The colonies are viewed under a 10X magnifying lens and distinguished from non-target bacteria based on the type, size and color of the colonies. Target bacteria are indicated by pigment production resulting from bacterial enzymatic reactions to specific substrates. The number of colonies present in 100 milliliters of water, also known as Colony Forming Units (CFUs), is counted and the concentration of organisms in the original sample is calculated.

15 Public Notification and Risk Communication Public notification and risk communication is a critical component of the Ocean Water Protection Program. Public awareness and enhancing the capacity for informed personal choice are important factors in ensuring public health protections are provided to recreational water users. The Ocean Water Protection Program has established and maintains an integrated management system to inform the public of the potential health risks associated with water contact activities in coastal recreational waters that do not meet applicable water quality standards. Multiple communication measures are promptly taken to notify the public when ocean, harbor or bay water areas do not meet or are expected not to meet AB 411 Ocean Water-Contact Sports Standards. The Ocean Water Protection Program implements the following types of public notification measures to communicate information regarding beach water quality and to protect the health of beach users: Beach Signs Signs are posted to notify beach users of the current status of the ocean, harbor or bay water area. Posted beach signs are located where they are most likely to be noticed by beach users and provide a visual notice at the point of ocean water access. Telephone Hotline The Ocean, Harbor and Bay Water Closure & Posting Telephone Hotline has been established to inform the public about all beaches that are currently closed, posted with a health warning or when a rain advisory has been issued. The telephone hotline message is immediately updated when a change in the status of beach closures, postings or advisories occur. The Ocean, Harbor and Bay Water Closure & Posting Telephone Hotline is (714) Web Page The Ocean, Harbor and Bay Water Closure & Posting Web Page has been developed and is used to report beach closures, postings and rain advisories. The web page is updated immediately when the status of the closure, posting or advisory changes. The Ocean, Harbor and Bay Water Closure & Posting Web Page internet address is Social Media Public notification of ocean water quality status changes are being communicated to the public through the social media network of Twitter. For the latest information and instant ocean water quality updates when they occur, follow us on Twitter at Press Releases Public notification of a beach closure or rain advisory is provided in a press release issued by the Health Care Agency. The press release will indicate whether a closure or advisory is being issued, the reason for the closure or advisory, the area affected and the anticipated duration of the closure or advisory. Annual Reports To assess the health of the ocean, harbor and bay waters being monitored, the Ocean Water Protection Program compiles an annual report of the beach closures, postings and advisories after the year has ended. The Annual Ocean, Harbor and Bay Water Quality Report provides an updated analysis of bacteriological water quality, describes year-to-year variability and trends for Orange County s recreational waters, and includes data on sewage spills and beach closures. Annual Reports from 2002 to present can be viewed and downloaded from the Ocean, Harbor and Bay Water Closure & Posting Web Page at Current information about OC water conditions is available at Twitter and the Closure & Posting Telephone Hotline Annual Ocean, Harbor & Bay Water Quality Report - Page 5

16 Closure and Warning Signs The yellow closure sign is posted when a sewage spill affects ocean or bay waters adjacent to a public beach. This sign is also available in Spanish. The warning sign with the red and black border is posted when a violation of the AB 411 Ocean Water- Contact Sports Standards occurs. The warning sign with the yellow and black border is permanently posted near storm drains, creeks and rivers to advise the public of the risks associated with possible contamination from urban runoff and confirmed violations of the AB 411 Ocean Water- Contact Sports Standards where runoff physically enters the ocean at the receiving zone. he receiving zone is considered to be from 75 feet upcoast to 75 feet downcoast of the flowing drain, creek or river Annual Ocean, Harbor & Bay Water Quality Report - Page 6

17 Beach Mile Days (BMD) The term Beach Mile Days is used to represent the measurement of the number of days and the linear area of ocean, harbor or bay front waters that are closed due to a sewage spill or posted for a violation of the AB 411 Ocean Water-Contact Sports Standards. Beach Mile Days (BMD) are calculated by multiplying the number of days of a closure or posting by the number of miles of beach closed or posted: (Number of Days) x (Miles of Beach Closed/Posted) = Beach Mile Days For example, if a sewage spill resulted in the closure of ½ mile of beach for 7 days then: (7 days) x (0.5 miles of beach closed) = 3.5 Beach Mile Days of closure Another example, if 300 feet of beach is posted for a violation of the AB411 Ocean Water-Contact Sports Standards for 5 consecutive days, then: (5 days) x (0.06 miles of beach posted) = 0.3 Beach Mile Days of posting Using BMD as a measurement of ocean and bay water availability is more meaningful than using the number of incidences or the number of days since BMD take into account both the length of beach and number of days for a closure or posting. The State of California Water Resources Control Board and all California coastal counties use BMD for reporting closures and postings which provides a standardized measurement that allows comparison of different areas (beach to beach or county to county) and the assessment of closure and posting trends over time.

18 SEWAGE WASTE DISCHARGES Sewage waste discharges commonly known as sewage spills occur when wastewater being transported via underground pipes overflows through a manhole, clean-out drain or broken pipe. Sewage spills can cause health hazards, damage to homes and businesses and threaten the environment, local waterways and beaches. Untreated sewage has high levels of disease-causing bacteria and viruses. Orange County Health Care Agency/Environmental Health is responsible for protecting public health by closing ocean, harbor and bay water areas affected by sewage spills and will close food-service establishments if a sewage spill poses a threat to public health. Common Causes of Sewage Spills: Grease builds up inside and eventually blocks sewer pipes. Grease gets into the sewer from food establishments, household drains, as well as from poorly maintained commercial grease traps and interceptors. Infrastructure problems caused by tree roots in the lines, broken/cracked pipes, missing or broken cleanout caps or undersized sewers can cause blockages. Infiltration and inflow impacts pipe capacity and is caused when groundwater or rainwater enters the sewer system through pipe defects and illegal connections. Local and state agencies have legal jurisdiction and enforcement authority to ensure sewage spills are remediated. Allowing sewage to discharge from a home, business or public property may subject the responsible party to penalties and/or out-of-pocket costs to reimburse local and state agencies for clean-up efforts and for not reporting the sewage spill. As mandated by the California Health and Safety Code, any person who causes or permits a sewage discharge to any state waters must immediately notify the local health agency of the discharge. If you see a sewage spill occurring, immediately notify your City Sewer/Public Works Department or Public Sewer District.

23 OCEAN, HARBOR AND BAY WATER CLOSURES DUE TO SEWAGE SPILLS When a known release of sewage is reported to the Ocean Water Protection Program, the ocean or bay water areas that may be affected by the sewage discharge are immediately closed to water-contact recreational activities. The closure area is based on many factors including type of sewage (e.g., untreated, secondary treated, etc.), volume of spill, location of spill, ocean currents and tides, historical sewage spills in the area and other pertinent information. After the initial closure area is established, the appropriate agencies are notified, the area is posted with closure signs, a press release is issued, the Ocean, Harbor and Bay Water Closure & Posting Telephone Hotline and Web Page are updated with the beach closure information, and daily bacterial sampling of the affected area is initiated. The closed ocean or bay water area will be reopened or reduced in size when the contamination source has been eliminated and after two daily consecutive sampling results indicate the affected area meets the AB 411 Ocean Water-Contact Sports Standards. The Ocean, Harbor and Bay Water Closure and Posting Telephone Hotline, web page and Twitter account provide the current status information for beach closures and are immediately updated when a change of status occurs. In addition, detailed information regarding Orange County beach closure events from 1999 to the present can be viewed and downloaded from the web page.

30 OCEAN, HARBOR AND BAY WATER POSTINGS DUE TO BACTERIOLOGICAL STANDARDS VIOLATIONS Upon implementation of the AB 411 Ocean Water-Contact Sports Standards in July of 1999, the Ocean Water Protection Program began posting the required health warning signs at public beaches where the ocean, harbor or bay waters failed to meet state mandated recreational water quality standards. From April 1 to October 31 bacteriological water samples are collected a minimum of once a week at approximately 140 ocean, harbor and bay locations throughout Orange County. Sample results are reviewed daily by the Ocean Water Protection Program to determine compliance with the seven AB 411 bacteriological standards established by the State of California. Each year the Ocean Water Protection Program will review bacteriological results of approximately 3800 ocean, harbor and bay water samples collected from April 1 to October 31. When a bacteriological water sample fails to meet an AB 411 Ocean Water-Contact Sports Standard, the following actions are taken: Warning signs are posted at the affected ocean, harbor or bay water area indicating that bacteria levels have exceeded health standards and ocean water contact may cause illness. The information regarding the posted area is updated on the Ocean, Harbor and Bay Water Closure and Posting Hotline at (714) , Web Page at and by Twitter at com/ocbeachinfo. Follow-up bacteriological water samples are collected at the posted location and the results are evaluated daily to determine if the posted area should be increased, reduced, shifted or removed. Because ocean, harbor or bay water areas that violate the AB 411 Ocean Water-Contact Sports Standards may cause illness to recreational water users, the Ocean Water Protection Program staff recommends staying out of the water at all beach areas that are posted with the health warning sign shown below Annual Ocean, Harbor & Bay Water Quality Report - Page 20

32 OCEAN, HARBOR AND BAY WATER RAIN ADVISORIES During and after a significant rainstorm event, storm drains, creeks and rivers carry floodwaters with urban runoff into local ocean, harbor and bay waters. Urban runoff may include fertilizers, road oils, litter and large amounts of bacteria from a variety of sources, such as animal waste and decomposing vegetation. The levels of bacteria can rise significantly in ocean and bay waters close to discharging storm drains and outlets of creeks, rivers and streams during and after rainstorms. To ensure that public health and safety is protected, the Ocean Water Protection Program staff advises against body-contact recreational use of ocean, harbor or bay waters where there may be contamination due to storm water carrying urban runoff. The elevated bacterial levels in ocean, harbor and bay waters may continue for a period of at least three days depending on the intensity of the rain and the volume of runoff. Swimmers, surfers and divers should avoid body-contact recreation with Orange County s ocean, harbor and bay waters during and after a rainstorm event and all beach users should avoid contact with any storm drain or creek runoff on the beach during dry or wet weather conditions. The Ocean Water Protection Program issues a Rain Advisory during or immediately after a rainstorm event that results in measured rainfall greater than or equal to two-tenths of an inch (0.20 ). If multiple rainstorm events occur during the 72-hour window of the previous rainstorm, the existing rain advisory continues for an additional 72 hours. Rain advisory information is provided by issuing a Rain Advisory Press Release to media outlets and on the Ocean, Harbor and Bay Water Closure and Posting Hotline at (714) , Web Page at and by Twitter at High Surf at Pier San Clemente 2015 Annual Ocean, Harbor & Bay Water Quality Report - Page 22

However, the sample stations 75 feet upcoast and downcoast were in compliance 96.8% of the time. Although Salt Creek flows through an ozone treatment facility before being discharged to the beach, the exact reason of the higher bacteria levels measured at point zero after treatment is unclear and may be the result of bird waste and decomposition of organic matter in the ponded flow on the beach. Further investigation is being conducted to determine the exact cause, but regardless of the cause the higher exceedance rates confirm why swimmers should avoid any ponded or flowing runoff and the area where it enters the ocean.

66 APPENDIX 6 Single Sample Standard Exceedance Rates for Point Zero Open Coastal Locations The following table shows the seasonal single sample standard exceedance rates at each of the new point zero monitoring stations for both the AB 411 and non AB 411 periods (dry and wet weather periods) for calendar year Point Zero monitoring is a departure from traditional methods of sampling beach areas to determine bacteriological water quality. Instead of monitoring a location within 100 feet of a storm drain, creek, or river to determine health compliance, samples are now collected in the surf where urban runoff physically mixes with the ocean and at points 75 feet upcoast and downcoast. If there is no urban runoff flow to the beach then only one sample is collected where flow would normally occur, or what is termed: virtual point zero. Permanent advisory warning signs continue to be posted at all drains, creeks and rivers advising beach goers to avoid urban runoff on the beach and where it enters the water because water quality can change significantly at any time. However, point zero monitoring serves to confirm exceedances of health standards at the receiving water and allows additional public notification which underscores the need to avoid urban runoff. Point zero monitoring stations are sampled at the surfzone whether or not the associated drain or creek is flowing. Point Zero is identified by the last letter of the Station ID. For example, a station ending with Z is point zero, such as POCHEZ. Similarly, the upcoast and downcoast stations that are sampled 75 feet upcoast and downcoast of the associated storm drain, creek or river will have an identifier ending in U or D, respectively. Since point zero monitoring was first implemented in April 2015, the non AB 411 rates (JAN-MAR / NOV DEC) only reflect 6 months worth of monitoring results for this report year. NS = No sample may have been collected during the period due to access issues or non-flowing conditions that eliminate the need for upcoast or downcoast sampling.
