Leadcan enterdrinking normal water when servicepipes, accessories, fixtures, solder andfluxthat contain leadcorrodeby achemical reaction with the normal water, especially wherethe normal water has high acidityor low mineral articles. The most common problem is with brassor chrome-plated instruments faucetsandfixtures with leadsolder, from which significantamounts of leadcan enter intothe water, especially with water. Toaddress corrosion of leadandcopper intodrinking normal water, the EnvironmentalProtection Agency(EPA) issuedtheLeadandCopper Rule (LCR)under theauthorityof theSafe DrinkingWater Actof1974(SDWA). TheLCR containsallof theregulatoryrequirements for monitoring, tracking, treatmentandreportingtoprevent leadandcopper from contaminating moving water. TheCityofPleasanton testsbetween 30and60singlefamily homesbuilt between 1982and1986onceevery3years tocomply with theEPA Lead andCopper Regulation. Pleasanton source normal water isanalyzedfor leadandcopper about aregular schedulespecifiedbytheStateWater ResourceControl Board (SWRCB).

Approximately80%of Pleasanton’s water ispurchasedfrom Zone7 andis comprisedof treatedsurface water mixed with somelocalgroundwater. The remaining20%comes from localgroundwaterpumpedfrom wellsownedand operatedbytheCityofPleasanton. Most water sourcesaredisinfectedandfluoridatedbeforedeliverytoour consumers. TheStateWaterProject (SWP)delivers normal water toZone7. TheSWP wateroriginates from theFeather Lake watershed, whereit is definitely storedbehindthe Oroville Ravage beforebeing releasedintotheSacramento River/San Joaquin Delta. This kind of water ispumpedfrom the Deltabythe DepartmentofWater Solutions (DWR) totheSouth Gulf Aqueduct (SBA) program, which then flows tothe Tri-Valleyarea. TheSBA carries on through AlamedaCountyandintoSantaClara State. Local Surface Normal water Lake Del Vallejo, our local drinking water storagereservoir, isoperatedand maintainedbythe DWR asa normal water supplyreservoir, local floodcontrol resourceandrecreation area. The storedatLake Del Vallecomes from local rainfallandfrom theSWP. Water by Zone 7’s twosurfacetreatmentplants (Del Valle andPatterson Pass)undergoes several stagesof treatment in order tocomply with theStateWater ResourcesControl Board (State Board), Division of DrinkingWater.

As water travelsover thesurfaceof thelandor through theground, itdissolves naturallyoccurring mineralsand, in somecases, radioactive material, andcan pickupsubstances resultingfrom the presenceofanimalsor from liveliness. Drinking water, includingbottled seas, mayreasonablybeexpectedtocontain at least smallamountsof some impurities. Thepresenceof contaminantsdoes certainly not necessarilyindicatethat waterposesa well being risk.
