PHSIEHD requested submittal of a mass balance estimate of <br /> the soil and groundwater contamination remaining from the diesel tank and 220 feet of <br /> piping. <br /> Franklin High School <br /> In order to determine the vertical extent of contamination in the area of B-•1 a <br /> groundwater sample should be obtained and analyzed for gasoline range hydrocarbons <br /> and its constituent components of benzene, toluene, ethyl benzene and xylenes. <br /> Additional investigation or closure will be based on the results of the groundwater <br /> analysis. <br /> Edison High School <br /> The vertical extent of contamination beneath tank 1 is unknown. Soil samples and if <br /> necessary a groundwater sample should be obtained and analyzed for diesel range <br /> hydrocarbons.
