Mr. Mike Infurna, SJCEHD was present <br /> to witness this sampling event. Once again, the three wells were purged of a minimum of four casing well <br /> volumes. Measurements of pH,temperature, and conductivity were recorded and depth to groundwater was <br /> measured. The water samples were collected in a stainless steel bailer and transferred to 40 ml VOA vials. <br /> The results are presented in Table 11. <br /> TABLE-11 <br /> Analytical Results -Water Samples <br /> 11-05-98 <br /> �.
