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. 200,000. 2,500. ug/l 50 <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 /> The vial submitted for volatile analysis did not have a pH < 2 at the time <br /> of analysis. Due to the volatile nature of the analytes, it is not <br /> appropriate for the laboratory to adjust the pH at the time of sample <br /> receipt. <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. 1,900. 1,000. ug/l 1 <br /> 02508 TPH Motor Oil C16-C36 n.a. 1, 900. 11000. ug/l 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 /> 0 C8 (n-octane) through C40 (n-tetracontane) normal hydrocarbons. <br /> Site-specific MS/MSD samples were not submitted for the project.
