MPDS UN5098 14 <br /> October 17 1997 <br /> Page 6 of 7 <br /> Table 2 <br /> Summary of Laboratory Analyses <br /> Water <br /> * Nitrates were non-detectable, and coliform bacteria were below detection Iumts <br /> ** All EPA method 8010 constituents were non-detectable, except for concentrations of bromo- <br /> dichloromethane at 0 53 lig/L, chloroform at 1 4µg/L, and dibromochloromethane at 0 97 lig/L. <br /> $ Sequoia Analytical Laboratory reported that the hydrocarbons detected appeared to be a gasoline <br /> and non-gasoline mixture <br /> # Sequoia Analytical Laboratory has identified the presence of MTBE at a level above or equal to the <br /> taste and odor threshold of 40 lig/L in the sample collected from flus well <br /> ft Sequoia Analytical Laboratory has potentially identified the presence of MTBE at reportable levels <br /> in the ground water sample collected from this well <br /> t Well has been destroyed <br /> MTBE = methyl tert butyl ether <br /> -- Indicates analysis was not performed <br /> ND = Non-detectable <br /> Results are in micrograms per liter(µg/l_), unless otherwise indicated <br /> Note The detection limit for results reported as ND by Sequoia Analytical Laboratory is equal to the <br /> stated detection limit tinies the dilution factor indicated on the laboratory analytical sheets <br /> Prior to August 1, 1995 the total purgeable petroleum hydrocarbon(TPH as gasoline) quantification <br /> range used by Sequoia Analytical Laboratory was C4 -C12 Since August 1, 1995, <br /> the quantification range used by Sequoia Analytical Laboratory is C6 -C12 <br /> All EPA method 8010 constituents were non-detectable, except as reported above <br /> Laboratory analyses data prior to December 20, 1993, were provided by Kaprealian Engineering, Inc <br />
