Annular volumes will be multiplied by 30s to account for <br /> porosity of filter pack. <br /> If the aquifer is slow to recharge, development will <br /> continue until recharge is too slow to practicallx continue. <br /> The volume of water produced versus time will be recorded. <br /> All withdrawn groundwater will be Ltored on-site in 55 <br /> gallon waste drums unless permission is granted by the <br /> ' appropriate regulatory agency to discharge the water to the <br /> r ground surface or srnitary sewer. Drummed water will be <br /> 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 <br /> Authority with proposed boring/sampling locations. The <br /> exact location and number of borings at each site will be <br /> determined in the field by the Project Geolcgist/Engineer. <br /> Prior to arriving at the sample site, the drill rig/augers <br /> _ will be steam cleaned and all sample equipment will be <br /> cleaned. Cleaning will be conducted on-site on all sampling <br /> equipment b-etwee n each-sample_interval. <br /> Soil samples will be obtained .using a California modified <br /> Split-spoon sampler containing three, six inch long; two . <br /> inch diameter brass tubes. The sampler will be driven 18 <br /> inches ahead of the hollow stem auger by a 140 pound hammer <br /> with a 30 inch drop in accordance with American Society for <br />
