water samples had been chlorinated. As requested by Mr. Hodek, Mr. Larson installed a <br />spigot on the raw water line (Figure 2, Attachement C) and turned the pump off to <br />deternune if the well was currently artesian. Mr. Hodek and Mr. Larson observed that the <br />groundwater flowed freely from the hose attached to the raw water line spigot (Figure 3, <br />Attachment C), thus indicating that the well was currently under artesian pressure and has <br />raised the groundwater about 800 feet above the top of the Dakota Sandstone to ground <br />level. <br />-Mr.-Hodek-collected a-groundwater-sample-from-the-new raw water-spigot andsubmitted <br />it for analysis. These results of this sample will be reported to the DMG upon receipt <br />from the laboratory. <br />n ese o serva ions a e all well; the Dakota an s one at t is ocation is <br />artesian. This condition would likely minimize migration of accumulated water in the C <br />Pit to the Dakota Sandstone, even if a hypothetical fracture existed between the C Pit and <br />the underlying Dakota Sandstone. This evidence suggests that it is not reasonable to <br />expect water from C-Pit to migrate to the Dakota Sandstone, and therefore, not necessazy <br />to monitor water quality in the underlying Dakota Sandstone. <br />A-2 <br />
