As part of the County of Orange Health CareAgency(HCA),EnvironmentalHealth’sOceanWaterProtectionProgramisresponsible forprotecting thepublic fromexposure tooceanandbaywaters thatmay be contaminated with sewage or may causeillness along Orange County’s 42 miles of openocean coastline and 70 miles of harbor and bayfrontage.Oceanandbaywatersusedforbody-contactrecreationalactivitiessuchasswimming,surfinganddivingmustmeetspecificbacteriologicalstandardstobeconsideredsafeforsuchpurposes.
Over the past 40 years, the Health Care Agencyand two local sanitation agencies (Orange CountySanitation District and South Orange CountyWastewaterAuthority)havebeencooperativelytestingthe coastal waters in Orange County for bacteriathat indicate the possible presence of disease-causingorganisms.ThesanitationagenciesandHCAprogram staff participate in the weekly collection ofwatersamplesatapproximately150ocean,bayanddrainagelocationsthroughoutcoastalOrangeCounty.Eachyear,thesanitationagenciesandHCAroutinelycollect over 13,300 water samples and performapproximately40,000analysesfortherequiredthreetypes of indicator bacteria (i.e., total coliform, fecalcoliformandenterococcus).TheHealthCareAgencyandtheOrangeCountySanitationDistrictcollectandanalyzeover5,000samplesper yeareach,and theSouth Orange CountyWastewater Authority collectsandanalyzesover3,300samplesperyear.
Ocean Water Proctection Program staff review thebacteriological water sample results daily and issueocean and bay water closures, postings and healthadvisories under the requirements stipulated by the

Indicator Bacteria Testing Methods
The detection and enumeration of disease-causingorganisms (pathogens) identified with waterborneillness is difficult, time-consuming and costly. Thus,mostwaterquality laboratories test for fecal indicatorbacteria (i.e., total coliforms, fecal coliforms andenterococci) as a means to ascertain the likelihoodthathumanpathogensmaybepresentinrecreationalwaters.Fecal indicatorbacterianormallyoccur in theintestinesofallwarm-bloodedanimals,areexcretedinhighnumbersinfeces,butcanalsobefoundinsoilanddecayingvegetation.Since there isno ideal indicatorgroup, water should be tested for more than oneindicator.TotalcoliformsareabroadgroupoforganismsthatincludefecalcoliformbacteriaaswellasE.coli.Theenterococcigrouphasbeendeterminedtobeagoodindicatorof swimmingassociatedgastroenteritis.Themethodsmostcommonlyusedtodetectfecalindicatorbacteriainwaterinclude:

Allofthemethodsareculturebased,whichmeansthattheindicatorbacteriapresentinwatermustbeallowedtogrow in order to bedetected.Differencesbetweenthemethodsincludehowthebacteriaaredetectedandcounted,howsoontheresultsbecomeknown,andcost.Each method has its advantages and disadvantages.Mostof the limitationsdependonfactorssuchas theothertypesofconstituentsinthewateranddensityofbacteria present, and all require at least an 18-hourincubationperiod.Thefollowingisabriefsummaryofthesemethods.DetaileddescriptionsforthesemethodsareavailableinthelatesteditionofStandardMethodsfortheExaminationofWaterandWastewater.

OCEAN AND BAY WATER CLOSURES DUE TO SEWAGE SPILLS
WhenaknownreleaseofsewageisreportedtotheOceanWaterProtectionProgram,theoceanorbaywater areas that may be affected by the sewagedischarge are immediately closed to body-contactrecreational activies.The closure area is based onmanyfactorsincludingtypeofsewage(e.g.,untreated,secondary treated,etc.),volumeofspill, locationofspill,oceancurrentsandtides,historicalsewagespillsinthearea,andotherpertinentinformation.Aftertheinitial closure area is established, the appropriateagenciesarenotified,theareaispostedwithclosuresigns,apressreleaseisissued,theOceanandBayWaterClosureandPostingHotlineandWebPageareupdatedwiththebeachclosureinformation,anddailybacterialsamplingoftheaffectedareaisinitiated.

OCEAN AND BAY WATER POSTINGS DUE TO BACTERIOLOGICAL WATER QUALITY STANDARDS VIOLATIONS
Upon implemention of the AB 411 Ocean Water-ContactSportsStandardsinJulyof1999,theOceanWaterProtectionProgrambeganpostingtherequiredhealth warning signs at public beaches where theoceanorbaywatersfailedtomeetthebacteriologicalstandards.
Bacteriological water samples are collected eachweekatapproximately150ocean,bayanddrainagelocations throughout Orange County. The OceanWater Protection Program receives the resultsof 650-750 bacteriological ocean and bay wateranalyseseachweek.Theresultsarerevieweddailytodeterminecompliancewiththesevenstandards.
When a bacteriological water sample fails to meetany of the AB 411 Ocean Water-Contact SportsStandardsthefollowingoccurs:
•Warningsignsarepostedattheaffectedoceanor bay areas indicating that the waters haveexceededhealthstandards.
•The information regarding the posted areas isupdatedon theOceanandBayWaterClosureandPostingHotlineat(714)433-6400andWebPageatwww.ocbeachinfo.com.
• Additional bacteriological water samples arecollected at the posted areas and the resultsare evaluated daily to determine if the areaspostedwithwarningsignsshouldbeincreased,reduced,shiftedorremoved.
Becauseoceanorbaywaterswhichviolate theAB411 Ocean Water-Contact Sports Standards maycauseillnesstousers,theCountyofOrangeHealthCareAgency recommendsstayingoutof thewaterat all beach areas that are posted with the healthwarningsignshownbelow.
