7. WELL DEVELOPMENT <br /> According to Attachment A of the General Order for Existing Milk Cow Dairies, well <br /> development is to occur at least seven days after well completion. It is in our <br /> professional opinion and the industry standard that development should occur within <br /> 24 hours of well completion in order to remove fine material emplaced during drilling <br /> from the wellbore wall, screen and casing. This seven day wait period will also be <br /> erroneously expensive to mobilize a drilling company twice when the original work <br /> will take less than a day. An exemption from this requirement is currently being sought <br /> by DE. <br /> Development will consist of surging the well with a swab, then bailing the well to <br /> remove sediments brought into the well. The procedure will be repeated until coarse <br /> sediment is removed. After surging and bailing activities, a variable speed pump or <br /> airlift may be used to further develop the well, if possible, to obtain the lowest turbidity <br /> attainable. Development will continue until the water retrieved is substantially free of <br /> visible, settleable solids and field parameters of pH, specific conductivity, temperature, <br /> and turbidity stabilize. A turbidity of 10 NTU or lower will be the goal. Development <br /> water is not anticipated to be contaminated, thus development water will not be <br /> contained. <br /> 8. WELL SURVEYING <br /> After well installations are complete, the well network will be surveyed to determine <br /> the horizontal position and the vertical elevation of the well measuring point. Well <br /> locations will be determined as Northing and Easting coordinates to+/- 1 foot. <br /> Measuring point elevations will be determined to the top of the PVC casing to+/- 0.01 <br /> feet. In addition, a point on the concrete well pad will be surveyed to+/- 0.1 foot. The <br /> datum will be the Mean Sea Level. Wells will be surveyed to coincide with a common <br /> reference point to the State Plane or UTM coordinate system. <br /> 9. WELL SAMPLING <br /> After the new wells are installed and developed, sampling of the wells will be <br /> conducted. In addition, up to five water supply wells will be sampled to obtain <br /> regional water quality. The selected wells will be based on the specific reconnaissance <br /> of each well, well yield, and availability of well log.
