`. <br />Souza 11 LLC <br />Tank Pull Report <br />Page 2 of 2 <br />Concentrations detected in the samples collected from the excavation were 596 parts per million <br />(ppm) and 110 ppm, respectively. <br />Subsequent to the collection of the soil samples, groundwater was observed percolating into the <br />pit at a depth of approximately 12 feet below ground surface (bgs). <br />Per the request of PHS/EHD, two discrete stockpile samples were collected in lieu of composite <br />samples. Stockpile samples were collected at the median point on the east and west sides of the Tank <br />4 stockpile. Approximately 65 yd was excavated. Soil sample analysis consisted of TPHd, TPHg, <br />gasoline oxygenates, BTEX, and total lead as per the request of PHS/EHD. PHS/EHD did not require <br />groundwater samples. <br />The excavation was partially backfilled with pea gravel. The balance was to be backfilled with clean <br />native soil derived from ongoing construction activities at the site. <br />
