EXECUTIVE SUMMARY

The2015AnnualOcean,HarborandBayWaterQualityReportprovidesanupdatedanalysisofbacteriologicalwaterqualitydataforOrangeCounty’srecreationalwatersandincludesdataonsewagespillsandrelatedocean,harborandbaywaterclosures.Theannualreportalsodescribesyear-to-yearvariabilityandtrendsrepresentingthe16-yearperiod(2000–2015)thatAssemblyBill411(AB411)OceanWater-ContactSportsStandardsforbacteriologicalwaterqualityhavebeeninplace.Inaddition,theannualreportincorporateshistoricalsewagespillandassociatedocean,harborandbaywaterclosureinformationduringthemostrecent29-yearperiodfrom1987–2015.

Major findings of the 2015 Annual Ocean, Harbor and Bay Water Quality Report:

Sewage Spills and Ocean, Harbor and Bay Water Closures

• ThetotalnumberofsewagespillsreportedtotheOceanWaterProtectionProgramin2015was133,continuingasteadydeclineanddown67.4%fromthepeakrecordof408spillssetin2002.

• During2015,thetotalnumberofsewagespillsresultinginbeachclosures(10)remained53%belowthe29-yearaverageof19beachclosuresperyear.

• ThetotalnumberofBeachMileDays(BMD’s)duetosewagespillclosureswas18.9andis33%belowthe17-yearaverageof28.2BMD’sfrom1999through2015.

• Pipelineblockagescontinuetoberesponsibleforthemajorityofsewagespillsresultinginbeachclosures.Since1999,blockageshaveresultedin62%ofallclosuresandoverhalfoftheseblockages(56.5%)werecausedbyinfiltrationofrootsordepositionofgrease.

• Anewunifiedregionalmonitoringplanwasimplementedatsouthcountybeachesatthebeginningofthe2015AB411period(April1toOctober31).Theplanrequires“pointzero”monitoringatlocationswhereurbanrunoffphysicallyenterstheocean.FirstyearmonitoringresultsduringtheAB411periodshowed20outofthe28pointzerostationswerein100%compliancewithoceanwaterhealthstandards.SeeAppendix6foradditionalinformationaboutpointzeromonitoringresults.

• TotalBeachMileDayspostedduetobacteriologicalwaterqualitystandardsviolationsduringtheAB411period(April1toOctober31)were36.2whichis90.1%belowtherecordhighof366recordedin2002.Thecontinuingtrendofrecordlowsoverthelast3yearsislikelyduetodroughtandlessrunoffimpactingthebeach.
