A LCS/LCSD <br /> was performed to demonstrate precision and accuracy at a batch level. <br /> The observed sample pattern is not typical of diesel/#2 fuel oil. <br /> 01412 Methanol and Ethanol <br /> 01414 Methanol (by Direct Injection) 67-56-1 N.D. 1,000. ug/l 1 <br /> 01729 TPH-GRO - Waters <br /> 01730 TPH-GRO - Waters n.a. 60. 50. ug/l 1 <br /> The reported concentration of TPH-GRO does not include MTBE or other <br /> gasoline constituents eluting prior to the C6 (n-hexane) TPH-GRO range <br /> start time. <br /> A site-specific MSD sample was not submitted for the project. A LCS/LCSD <br /> was performed to demonstrate precision and accuracy at a batch level. <br /> 02500 TPH Fuels by GC (waters) <br /> 02501 Total TPH n.a.

N.D. 1,000. ug/1 1 <br /> TPH quantitation is based on peak area comparison of the sample pattern to <br /> that of a hydrocarbon component mix calibration in a range that includes <br /> C8 (n-octane) through C40 (m-tetracontane) normal hydrocarbons. <br /> Site-specific MS/MSD samples were not submitted for the project. A LCS/LCSD <br /> was performed to demonstrate precision and accuracy at a batch level. <br /> 8214 STEX, MTBE (8021) <br /> 00776 Benzene 71-43-2 1.3 0.50 ug/1 1 <br /> lane ter L boratori s, C.#=Laborato t ect�g & W OW9 `target detection limit <br /> N.D.-Not d orm ithe Reporting Limit <br /> Lancaster,PA 17605-2425 <br /> 717-656-2300 Fax:717-656-2681 2216 Rev.9/11100 <br />
