(PQL for BTEX=0.0005 ppm, TPH,as gasoline and diesel=0.05 ppm) or as indicated in laboratory reports. << = Below indicated detection limit. " = Gasoline and diesel were reported as total purgeable petroleum hydrocarbons. ** = The positive result for petroleum hydrocarbon as gasoline appears to be due to the presence of heavier hydrocarbon rather than gasoline. FLH = Floating liquid hydrocarbons. The groundwater analytical results prior to February 1, 1991,are summarized from work conducted by previous consultants.
