Sequoia Analytical Laboratory reported that the hydrocarboris detected appeared to be a diesel and non-diesel mixture. # All EPA method 8270 constituents were non-detectable, except for 1,2-dichlorobenzene at a concentration of 4.2 µg/L. In addition, the following compound was tentatively identified by EPA method 8270 "open scan" analysis: 1,1'-[(I-methyl-1,,2-ethanediyl)bis(6xy)]-bis-2-propanoI at a concentration of 660 }ig/L. ## All EPA method 8270 constituents were non-detectable, except for 1,2-dichlorobenzene at a concentration of 3.7 µg/L. ii All EPA method 8010 constituents were non-detectable, except for chloroform which was detected at a concentration of 0.67 µg/L . All EPA method 8010 constituents were non-detectable, except for chloroform which was detected at a concentration of 0.51µg/1... ND = Non-detectable. Indicates analysis was not performed. mg1L = milligrams per liter. Results are in micrograms per liter(jAg/L), unless otherwise indicated. Note: All EPA method 8010 constituents were non-detectable, except as noted above. Laboratory analyses data prior to December 20, 1993, were provided by Kaprealian Engineering, Inc.
