The groundwater results <br /> table from 2013 Q1 is attached . Pictures of the wells are available on request. A picture showing MW-1 is <br /> attached . <br /> MW- 1 is within 1 foot (inches, really) of an on-site electrical line, and within two feet of a large sign footing and <br /> sign post. Workspace around the well would make drilling difficult at best, and the electrical line should <br /> preclude drilling at all . MW4 water samples were ND across the board during the sampling events in 2013. <br /> eli fin- 5041@2e ' oe <br /> MW-3 and MW-7 are within two feet of an on-site stormwater drain line . MW-3 may have originally been <br /> drilled through it, or displaced it during drilling. The most recent water sampling in these two wells showed <br /> concentrations of TBA between the drinking water and non-drinking water standards, but no other <br /> constituents. a" " <br /> MW-5 is within 5 feet of an on-site electrical line . MW-5 water samples were ND across the board during the <br /> sampling events in 2013. M ,vlo <br /> 2/ 10/2014 <br />
