The constituents for <br /> analysis, as well as preferred methods for the analyses, are presented in Appendix B. <br /> Monitoring of the newly-installed monitoring wells will then be incorporated into the MRP <br /> activities. <br /> Ir <br /> 4.4 Surveying <br /> The locations and well casing elevations of the new monitoring wells will be horizontally and 3T <br /> vertically surveyed by a licensed land surveyor. The ground surface and top of well casing <br /> elevation will be surveyed to the nearest 0.01 foot relative to mean sea level. The ground <br /> surface and top of casing will be surveyed to the North American Vertical Datum (NAVD) 1988, <br /> relative to the nearest benchmark for the Site. Horizontal locations of the new wells will also be <br /> surveyed relative to the California Coordinate system to 0.1 foot precision. <br /> 4.5 Residuals Management <br /> Residuals generated as a result of these activities are anticipated to include soil cuttings from <br /> the drilling activities, decontamination water from the drilling activities, water from development <br /> of the monitoring wells, and purge water from sampling of the monitoring wells. The soil cuttings <br /> will be distributed on the ground near each work site. Water residuals will be distributed on the <br /> ground near each well site in a manner that does not affect site safety. IT <br /> 4.6 Quality Assurance/Quality Control Procedures <br /> Field QA/QC will include collection of one field duplicate sample during each sampling event. <br /> The results of the duplicate sample will be compared to the primary sample for consistency. The <br /> laboratory will follow its standard internal QA/QC procedures during sample analysis, including <br /> elements such as analyzing method blanks and control spikes, where appropriate. <br /> Analytical data received from the laboratory will be reviewed immediately upon receipt for <br /> completeness and consistency. Any discrepancies will be discussed with the laboratory and <br /> corrective measures will be taken if warranted. <br /> .i <br /> it <br /> it <br /> R <br /> t,l <br /> R <br /> Page 12 Monitoring Well Installation Work Plan <br /> Sutter Home Winery, Lodi, California £— <br /> gYs-grauD�nyob10BW86'.A0517 sutlulpnea9aeparlsNwArtga&wp�LUrc `� <br />
