(POL 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 is an unknown which consistsof a singular peak. I=LH = Floating liquid hydrocarbons. The groundwater analytical results prior to February 1, 1991,are summarized from work conducted by previous consultants.
