A LCS/LCSD <br /> was performed to demonstrate precision and accuracy at a batch level. <br /> 01412 Methanol and Ethanol <br /> 014.14Hethanol=(by-Direct�ijecfion) 67-56-1 N.D. 1,000. <br /> ug/1 1 <br /> 01729 TPH-GRO - Waters <br /> 01730 TPH-GRO - Waters n.a. 75,000. 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 /> A site-specific MSD sample was not submitted for the project.
