These parameters will be noted on a field log. Instruments calibrated to <br /> known standards will be used to monitor these parameters. <br /> At least five well volumes will be evacuated from each well, and more, if necessary, <br /> until the above parameters have stabilized. Wells that are de-watered before <br /> evacuation of five well volumes has been accomplished will be sampled upon eighty <br /> percent recovery of the initial water level. The wells or other sampling points will be <br /> sampled in order of the least to the most contaminated, as best known or estimated. <br /> The samples will be pumped from a stainless steel bladder pump or carefully poured <br /> from a Teflon bailer into clean glass vials with Teflon-Iined screw caps and half gallon <br /> plastic containers provided by the laboratory. Care will be taken to ensure that no air <br /> space exists in the vials by inverting to check-for bubbles and re-sampling if necessary. <br /> The samples will be analyzed or e;ct.acted witlun fourteen 4:1ays_according to their EPA, <br /> "�metlhods W&er samples ccllected-for analysis will.be andlyzed•by :I;FA-mct4,ou,S:;)cI <br /> `£or`BTk&r---and'�niethod=LUQ= 55.078015 'for-TPH•Crasoline. ;4tJ: ses are to lie_ <br /> _ _ <br /> " cordiidted_b-y_abAnal`yical Laboratories;"Inc.,'a state certified!�bbfatoryr" <br /> ViRONNlF,�,�9 <br /> H.
