Nitrogen gas will be utilized to air lift <br />the samples. Samples are obtained after at least one evacual.i.on <br />of the sample zone to obtain a fresh aquifer sample. Field <br />measurements will. be noted throughout evacuation (first cycle) <br />and subsequesnt cycle(s) to determine when water quality <br />stabilizes and theerefore when to obtain the water sample. <br />Pield Measurements 1'Monthly) by NaTec Samples - 1 <br />temperature pH conductivity <br />Lab Analyses - Maior Components (Ouarterlvl by Contract Lab.
