The pump <br /> was flushed by pumping the solution through the pump and hose. The exterior of the <br /> pump, hose, and electrical leads were then rinsed with potable water. Potable water was <br /> pumped through the pump and hose. The pump was then rinsed with potable water. <br /> ' After purging, sampling of each well was conducted using new, clean, dedicated <br /> disposable polyethylene bailers. The bailers were lowered into the wells via new <br /> dedicated poly cords, samples collected, and gently poured into two laboratory provided <br /> clean glass VOA vials. Each VOA vial was immediately sealed, checked for headspace, <br /> labeled with the date, time and location and placed in a cooler containing blue ice at 4° <br /> Celsius. <br /> 1 <br /> ' American Geological services, Inc. <br /> CA95 DE-029 <br /> i <br />
