An additional sample from each interval will be screened with a photo- <br /> ionization detector. <br /> 4) Submit the two deepest soil samples from each boring to a state-certified analytical <br /> laboratory and analyze for TPHg by modified EPA Method 8015 (PQL = 1.0 ppm) and <br /> benzene, toluene, ethylbenzene, and total xylenes (BTEX) by EPA Method 8020 (PQL <br /> = 0.005 ppm). <br /> 5) Submit a results report summarizing the investigation findings. <br /> The borings will be terminated approximately 40 feet bg. Ground water should not be <br /> encountered. The fieldwork will be performed after agency approval and appropriate permits <br /> have been obtained. A results report will be submitted within 60 days of receipt of the laboratory <br /> analytical results. <br /> 95470571.AWP -3- <br />
