v <br /> carbon canisters prior to entering the plumbing system for the residences <br /> on the property Each of the carbon canisters is filled with 250 pounds of <br /> virgin 1230 mesh activated carbon The system is automated with <br /> levellpressure switches and timers that will allow for approximately 50 <br /> gallons of treated water for usage by the tenants at all tinges <br /> The air-stripper and each carbon canister has a sample port which allows <br /> a sample to be collected and analyzed at prescribed intei\ als to determine <br /> at what point MTBE has broken through a canister ASE will replace the <br /> canisters when they no longer are effective at removing the MTBE from <br /> the water Currently, the schedule for sample collection and analysis is <br /> quarterl) <br /> WATER SIMPLE COLLECTION AND ANALYSIS <br /> After the system was installed, started, and operating, ASE collected <br /> baseline samples for analysts On October 29, 2001, a %nater sample was <br /> collected from the well prior to treatment This sample was labeled <br /> 17950-INF-10 29 01 The sample was placed within an ice chest <br /> containing wet ice while transported to Kiff Analytical of Davis, California <br /> (ELAP# 2236) under chain of custody procedures The sample was <br /> analyzed tar total petroleum hydrocarbons as gasoline (TPH-G), benzene, <br /> toluene, ethylbenzene, and xylenes (collectively known as BTEX), the five <br /> fuel oxygenates, and lead scavengers by EPA Method 8260B The sample <br /> only contained 54 parts per billion (ppb) MTBE <br /> On November 7, 2001, a water sample was collected immediately after the <br /> air stripper This sample was labeled 17950-AS-11 07 01 ASE also <br /> collected a water sample after treatment by the first carbon canister This <br /> sample « as labeled 17950-GAC1-11 07 01 The samples were placed <br /> within an ice chest containing wet ice while transported to Kiff under <br /> chain of `ustody procedures The samples were analyzed for TPH-G, BTEX, <br /> Live fuel oxygenates, and lead scavengers by EPA Method 8260B The AS <br /> sample contained 41 parts per billion MTBE, the GACl sample was n o n <br /> detect for all compounds A copy of the certified anal,, tical reports are <br /> attached in Appendix B <br /> - 2 - <br />
