Volume of Open Borehole and Annular Space <br />Between Casing and Hole <br />*Note: Annular volumes will be multiplied by 30% 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 practically continue. <br />The volume of water produced versus time will be recorded. <br />All withdrawn groundwater will be stored on-site in 55 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 />ground surface or sanitary 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 Geologist/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 between 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.
