The volume of water produced versus tome will be recorded <br /> All withdrawn groundwater well be stored on-site in 55 gallon waste drums unless permission <br /> is granted by the appropriate regulatory agency to discharge the water to the ground surface or <br /> sanitary sewer Drummed water will be labeled with the source of the water to help ensure <br /> appropriate disposal based on contamination levels <br /> 11.0 SOIL SAMPLING PROTOCOL <br /> 11.1 SAMPLE COLLECTION DURING DRILLING ACTIVITIES <br /> A proposal will be submitted to the lead Regulatory Authority with proposed boring/sampling <br /> locations The exact location and number of borings at each site will be determined in the field <br /> by the Project GeoIogist/Engineer <br /> • <br />
