1 , <br /> 1 <br /> 6 <br /> On June 29, 1992, Sun Tech sampled monitoring wells 6, 7, 10, 11, 12 and 13. MW-4 <br /> was dry, and therefore not sampled. The groundwater samples were analyzed by a <br /> California certified laboratory (Sherwood Labs Corp.) using EPA method 602 for BTEX <br />' analysis, with a detection limit of 0.3 ug/Kg, and EPA method 5030/Mod. 8015 for <br /> TPH-Gasoline analysis, with a detection limit of 50.0 ug/L (Table 9). <br />' TABLE 9 <br /> GROUNDWATER SAMPLE ANALYSES <br /> (6-29-92) <br /> .:::...:.:..:..::...::'•:y:•:iii:::c}:.:::.}:::}':::r::{.::::'.'.:.::::•:.;,�I� .. - :-a: :;:- ij.: ":.': ::. ..: <br /> '::i::i<::•:•:i::iii.:{..`::{{.::::::-::{vi:.'..iii:}:•;{.}}{y:i•:i•:{-i}!i/ -: :....:j '-. ..
