Notes: 1, 1999 sample results are highlighted. 2. Soll and Water samples were anBWW for petroleum constituerda using EPA Methods 801518020:results for water samples are reported by the laboratory in ugA and presented here In moll. Results for soil samples are reported In mylkg. B-Benzene,E a Ethylbwuene.T a Toluene,X-Xylene. Standard detection limits for BTEX constituents are 0.3 and 0.5 ugA for water samples and 0.005"for sal samples. TPHg-TOW Petroleum Hydros dmm as Gasoline:standard detection f mit for water samples is 50 ugA and for soil samples is 0.5 to 1.0 nVft. MTEE=Methyl-t4W Ether,standard detection limit far water samples is 5.0 ugA and for soil samples Is 0.05 mg/kg. 3. Soil samples 54037,S-041,and 6.047,and water samples W-017 were enatyzed for a"snstea using EPA Method 8260 to confirm apparent Initial detection of MTBE by EPA Method 8D15AM20. All water samples for 1999 ware analyzed by Method 8260. Method 6260 results aro reported in uglkp for soil samples and ugA for water samples. if MTBE result using EPA Method 8D15MM le not"A med by Method 826, the 8015/8020 resuK Is also reported as NO. MTBE a Methyl•t•Butyl Ether; DIPE-Dl4soprapyl Ether ETRE-Ethyl t-Butyl Ether;TAME-t-Amyi Methyl Ether TEA-tat-Butyl Alcohol. 4. Detection limits are variable on soil samples S4037,-041,and-047,and on water samples W-016 and-017 due to variable dilution factors. ' See iaborstory analytical data sheets for these samples In R&R,1998b for detection limits.
