Cotulla: <br /> Enclosed are laboratory analytical reports for soil samples <br /> collected by Groundwater Technology, Inc . (GTI ) from the property <br /> of Mr. Ray Farmer at the above referenced location. <br /> On November 11 , 1987 , GTI obtained soil samples from an excavated <br /> tank pit at the site. The results of laboratory analyses <br /> performed on the soil samples were outlined in a letter to your <br /> office dated December 16, 1987 . <br /> Upon review of analytical results of the initial samples taken <br /> from the bottom of the tank pit , it was determined that <br /> contaminated soil was still present . The pit was subsequently <br /> re-excavated to a depth of approximately 25 feet . On January 21 , <br /> 1987 , GTI returned to the site and obtained soil samples from the <br /> bottom of the excavated tank pit . Enclosed are the laboratory <br /> analytical results for the second round of sampling. The samples <br /> were analyzed for total petroleum hydrocarbons (TPH) as gasoline; <br /> benzene, toluene, ethylbenzene and xylene (BTEX) ; ethylene <br /> dibromide (EDB) ; and organic lead. For analysis methods or <br /> descriptions, please see enclosed laboratory results . <br /> Offires throughout the U.S., Canada and Overseas <br /> Western offices in: Tempe, AL; Concord, CA; Sacramento, CA, San Diego, CA; <br /> Torrance, CA; Ventura, CA;Englewood, CO;Renton, WA <br />
