8520101-R COT-8 bottom of MW-3 is actually the result of moisture accumulation in the well . and not- groundwater infiltration. In anticipation -of -a seasonal rise in M r the water table, another site visit will he made after the first few significant winter storms to- monitor for fluid levels and, if possible, -- sample Well MW-3. p . . Soil :Contamination 1 � ' Soil contamination was encountered to varying degrees in Borings MW-1 and MW-2 while no contamination was detected in Boring !MW-.3. Three samples from Boring MW-1 were submitted for analysis based primarily on headspace readings and odor notations made during drilling. Sample. MW1-25 was selected due to the high headspace reading and strong apparent hydrocarbon odor. Sample MW1-45 was chosen also because of its high headspace reading as well -as its close proximity to the water table (assumed to be 45 feet below grade .at the time of drilling). - The final sample, 'MWI-60, was submitted for analyses based- on the relatively high headspace reading and in an attempt to better evaluate the lower extent of verticai migration. ' Two samples (MW2-35 and MW2-45) were submitted from boring MW-2, again based primarily on headspace readings and proximity,to the assumed water table location. Similarly, two samples from the same depths (MW3-35 and MW3-45) in Boring MW-3 were selected from headspace readings and assumed rproximity to the water table. ' The results of the soil sample analyses found that Only one sample (MW2-35) taken from a depth of 36 feet in Boring MW-2 contained detectable TPH at a ' relatively high level of 2,200 mg/kg (ppm) . Moderate levels of BTEX were also found ,in that sample, although no lead or EDB �was detected. The sample from 46 feet in MW-2 (Sample MW2-45) was also found to. contain low levels of BTX. The only other soil sample containing detectable 11
