zo <br /> program. Chain-of-custody forms would be used to document who <br /> collected the sample, any sample transfers, and sample delivery to <br /> the laboratory. Names, dates, and times would be carefully <br /> recorded on these sheets. After the samples are collected, they <br /> would kept either in full view of the sample custodian, or securely <br /> locked at all times until shipped to the laboratory. <br /> Water-Level Depths <br /> Depth to water in each well would be measured with an electric <br /> sounder, prior to installing the submersible pump. The sounder <br /> would be calibrated with a steel tape prior to each measurement <br /> round. Elevations of the measuring points would be precisely <br /> determined by surveying. <br /> Field Measurements <br /> Temperature, pH, and electrical conductivity of the discharged <br /> water would be frequently measured during pumping, and the time of <br /> these measurements also recorded. <br /> Indicator Parameters <br /> A list of indicator parameters, based on the composition of <br /> pond wastewater, would be: <br /> calcium potassium <br /> bicarbonate ammonia <br /> PH total organic carbon <br /> chloride electrical conductivity <br /> organic nitrogen total dissolved solids <br /> Pump Tests <br /> Each of the monitor wells would be pump tested for four hours, <br /> after completion of development. Water levels would be frequently <br />
