G. WATER LEVEL MEASUREMENTS <br /> After well construction and before purging and sampling, the elevations of the <br /> top of casings will have been surveyed. Depth to water will be measured in each well <br /> to within 0.01 ft. Groundwater elevation will be calculated by subtracting the depth to <br /> water from the top of casing elevation. Depth-to-water measurements will be made <br /> prior to purging and after sampling. If there is measurable drawdown, recovery rate <br /> will also be measured. <br />
