Over-pumping of each well was performed utilizing a hand bailer. Groundwater extracted from <br /> each well was containerized in separate 55-gallon drums. <br /> 2- Ea <nrgP htc_tcW,;;;«; cm. :h well to. force the groundwater in the veli back and <br /> forth through the well screen in order to draw drilling-induced N;Wme^'e into the well for removal <br /> and to enable the filter media to set up around the well. <br /> - 3. The silt-laden groundwater was then extracted from each well until it was determined ;hat <br /> turbidity in the well had been reduced. Approximately 30 to 40 gallons of water were removed <br /> from each well and containerized during the development process. <br /> 4. Cuntainerized water determined to not be impacted by the contamination was subsequently <br /> disposed of down the storm drain. Containerized water determined to be impacted by the <br /> contamination was stored onsite pending future treatment. <br /> I <br /> W.i <br /> I-' <br /> 1 <br /> a ``i ANDERSON <br /> CONSULTING <br /> GROUP <br />
