A Chain of Custody will be <br /> filled out by the sampler. The tests run will be as follows: <br /> Test Detection <br /> Limits <br /> DHS TPH Method (gasoline) 500 ug/L <br /> EPA 602 for <br /> Benzene 0. 5 ug/L <br /> Toluene 0. 5 ug/L <br /> EthylBenzene 0. 5 ug/L <br /> Xylenes 0. 5 ug/L <br /> All laboratory results, well measurements and the Chain of <br /> Custody must be sent to our office for evaluation and the <br /> Preparation of the quarterly report. <br />
