McCall, <br />Administrator <br />M E M O R A N D U M <br />T0: Mined Land Reclamation Board <br />FROM: Mined Land Reclamation Staff -Randy Qverton <br />DATE: November 30, 1977 <br />RE: Hazeltine Investment Association, Inc. <br />As you remember, consideration of Hazeltine was continued from the last <br />Board meeting (Nov. 22-23) to the Dec. 15 meeting; the subject of <br />discussion is to be limited to water quality resulting from the operation. <br />The general concerns expressed were that the creation of a series of <br />lakes could result in the contamination of ground water by water infiltrating <br />from the South Platte River to the lakes, and then to the ground water <br />system. The possibility of deep wells for domestic supplies was also <br />discussed. <br />In considering the problem I contacted a number of individuals in the <br />Division of Water Resources, Dept. of Health, Statewide 208 Program, and <br />the Denver Regional Council of Governments. What follows is a brief <br />discussion of what I learned and conclusions made about Hazeltine's <br />effect on ground water quality surrounding their operation. <br />Deep Soft Water Wells - <br />Water from these wells comes from the Arapahoe formation. The formation <br />is wide ranging and general in nature; locating water in this formation <br />is not difficult. The Division of Water Resources says that in the <br />Henderson area, new irrigation wells are not being permitted, but there <br />is no limit or anticipated future limitations on new domestic wells <br />completed in the Arapahoe formation. Below the Arapahoe formation are <br />the Larimie Shale, the Fox Hills Sandstone, and then the Pierre Shale. <br />Water can also be obtained from the Fox Hills Sandstone. <br />Quality of the South Platte River vs. Alluvial Ground Water - <br />Nutrients and coliforms in the South Platte River at Henderson are <br />considered the major contaminate. Phosphate (P04) shows high levels <br />
