108 <br /> Hands Four Development Cooperative <br /> 5W Orange County, NC <br /> Page 3 <br /> the headwater of a tributary to Collins Creek in the eastern/center of the property. We <br /> observed several locations of diabase float across the site, but no diabase outcrops were <br /> observed. "f=loat"are loose pieces of rock that are not connected to an outcrop. When many <br /> pieces of float of the same rock-type are found in a defined area, it can indicate that same rock <br /> -type is present in situ nearby, or at some depth at the location where the float is found. We <br /> observed clusters of diabase float that were spread over 54- to 60-foot-long areas along cleared <br /> pathways.. We noted the location of each occurrence by recording the latitude and longitude of <br /> each area. Those locations are shown in Figure 4. <br /> Well Site Recommendations <br /> GMA employed the well siting principles generally recommended by Heath (1984) for water- <br /> supply wells in the Piedmont. This approach focuses on siting wells near draws on the sides of <br /> the valleys of perennial streams where the bordering ridges are underlain by substantial <br /> thicknesses of regolith. Wells should be located low in the drainage basin, and near the <br /> intersections of regional structural features (regional joints, foliation fractures, or faults). These <br /> structural features often correspond with local stream valleys. However, the primary criteria for <br /> well site recommendations for this site is the proximity to diabase dikes. The locations of the <br /> diabase float that we observed fall directly on the location of the diabase dikes identified by <br /> Geo-Solutions (Figure 4). Therefore, we conclude that we have documented the presence of <br /> diabase dikes on the subject property. <br /> GMA identified four potential well locations for this site. We used published geologic literature, <br /> Feld observations by geologists, and magnetic survey data to aid us in understanding_ the <br /> geology at the site and to select suitable well sites. The proposed well locations are shown in <br /> Figure 4. All the proposed well sites are located as low in the drainage basin area as possible, <br /> but most importantly they are each associated with inferred locations of diabase dikes. Most of <br /> these sites can be easily accessed along existing pathways and should require minimal clearing <br /> by the driller. While the wells are labelled A, B, C, and D, their Labelling order is not intended to <br /> indicate any order of significance. GMA suggests you start with a well site that has easy access <br /> for a drill rig (like A or B), or the site that best fits your development needs. <br /> We have identified four potential well locations: Three are near, or in, cleared pathways (wells <br /> A, B, C); one may be difficult to access (well D). Our well B is about 50 feet northeast of your <br /> Client Well Site #2 which we understand you already have permitted by DEQ. The DEQ may <br /> accept that location as being dose enough to their approved location to not require another site <br /> visit on their part. Contact DEQ for that determination. Please see Figure 4 for well locations. <br />
