The - <br /> samples were retrieved and inspected for. floating product, sheen, <br /> emulsion, and product odor. No 'sUbjective evidence of floating <br /> product, sheen, emulsion or <br /> #�► product odor-, was-=detected in. the <br /> samples from wells Mw-1through MW 4 . <br /> The wells were developed by air-` and water'-jetting and purged by <br /> Pumping approximately five well volumes of liquid. Following the - <br /> purge period, and after- well recovery tostatic water .level, <br /> water. samples were collected using-, a laboratory-cleaned teflon <br /> bailer. The- bailer .was- lowered through the air/water `interface - <br /> in order to .retrieve samples representative 'of the -formation <br /> water. <br /> i° <br /> F <br /> -- - - The samples were transferred -to laboratory:.clean 40 mlglass <br /> Volatile Organic Analysis (VOA). via-1s , made acidic by adding <br /> hydrochloric acids immediately sealed- with .teflon-lined caps , <br /> labeled, and-placed in. iced -storages for -transport to the` <br /> analytical laboratory for testing_, The Chain-of-Custody and <br /> �7., . ,. <br /> r <br /> A lied Geos stems. <br /> . <br /> pin Y t . ; <br />
