S <br /> 2-3 <br /> ,4 <br /> Following .installation, each well was developed using a stainless <br /> steel bailer to surge and bail the well. Throughout development, PH, <br /> specific conductance, and temperature of the discharged water were <br /> monitored, and development was continued until these parameters had <br /> stabilized and until the water was relatively sediment tree, PID <br /> ' readings for well w-1 indicated no accumulation of <br /> rouctors in <br /> the well, whereas readings for wells W-2 and W-3 indicated aproduct <br /> vapor accumulation. <br /> Each well was sampled on April 10, 1987, with a Teflon bailer <br /> equipped with a bottom-emptying valve. Approximately 25 to 3Q <br /> 4.., gallons of water were removed prior to sample collection. The sample <br /> was then drained directly from the bottom valve into four 90- <br /> „o milliliter glass bottles with Teflon-lined septums and into one half- <br /> liter plastic bottle containing nitric acid preservative. r,ht <br /> samples were stored on ice from the time of collection through <br /> delivery to the Brown and Caldwell laboratory. All groundwater <br /> praducedduring well development and sampling was contained and <br /> temporarily stored on the site in 55-gallon drums pending results of <br /> z the analytical tests. <br /> r <br /> t <br /> i The hollow-stem augers were steam--cleaned prior to use ai- eucl. <br /> borehole.
