Groundwater Monitoring Well Construction Workplan <br /> February 2024 <br /> Groundwater Quality Sampling <br /> Groundwater quality sampling of the monitoring wells will occur after the monitoring wells are <br /> constructed and analyzed for general minerals, nitrate, and drinking water metals. The samples <br /> will be analyzed by a California ELAP certified laboratory. Samples will be collected after <br /> purging the well until field parameters stabilize. Purge water will be placed into the adjacent <br /> depression. <br /> Surveying <br /> After completion of the monitoring wells, their location and reference point at the top of each <br /> well casing will be surveyed by a California licensed Professional Surveyor. Reference point <br /> elevations for the top of casings were surveyed to the nearest 0.01 foot relative to the North <br /> American Datum, 1983 (NAD83) State Planes Zone II (US Foot) for well location coordinates, <br /> and vertical datum North American Vertical Datum, 1988 (NAVD88). <br /> GEI Consultants, Inc. 23 <br />
