Wells that are <br /> de-watered before evacuation of 5 well volumes has <br /> been accomplished will be sampled upon 80 percent <br /> recovery of the initial water level. The wells or <br /> other sampling points will be sampled in order of the <br /> least to the most contaminated as best known or <br /> ,., estimated. The samples will be pumped from a <br /> stainless steel bladder pump or carefully poured from <br /> a teflon bailer into clean glass vials with teflon- <br /> lined screw caps and half gallon plastic containers <br /> provided by the laboratory. Care will be taken to <br /> ensure that no air space exists in the vials by <br /> inverting to check for bubbles and re-sampling if <br /> necessary. <br /> The samples will be analyzed or extracted within 14 <br /> days according to their EPA methods. Water samples <br /> collected for analysis will be analyzed by EPA methods <br /> 8013 modified, total petroleum hydrocarbons, and <br /> � ' .. 601/602 for purgeable aromatics and halrcarbons. <br />
