State of Wisconsin \ DEPARTMENT OF NATURAL RESOURCES WISCONSIN 101 South Webster Street Box 7921 OUT. OF NATURAL RESOURCES Madison, Wisconsin 53707 George E. Meyer TELEPHONE 608-266-2621 Secretary TELEFAX 608-267-3579 TDD 608-267-6897 CORRECTED COPY March 23, 1995 IN REPLY REFER TO: 3320 John and Ardell Dahl 6013 Winnequah Road 9 "" �-�. Madison, WI 53716 {;: ; 7=' I ',;l'.`?N C ,ri'.1i,;„:: : OF APPROVAL Dear Mr. and Mrs. Dahl: The Private Water Supply Section has received and reviewed your request for a variance to construct wells within 1, 200 feet of the nearest edge of an existing, proposed or abandoned landfill site. The Department is authorized by chapters 144 and 162, Stats. , to have general supervision and control over the waters of the state and to establish and enforce standards and rules for obtaining drinking water and protecting public health against polluted water supplies . Chapter NR 812, Wis . Adm. Code, is adopted pursuant to that authority. Section NR 812.08(4) (g)1, Wis. Adm. Code, requires a minimum separating distance of 1,200 feet be provided between a well or reservoir and the nearest edge of an existing, proposed or abandoned landfill site. According to the information you supplied, you own property located in the part of the NW1/, of Section 28 , T7N, R11E, Town of Cottage Grove, Dane County. A preliminary plat of the property has been prepared. An abandoned land fill that was operated by the Township of Cottage Grove is also located in the NE1A of NW1A of Section 28, directly across from Nating Road and within 100 feet from the above-described property. An examination of the water table map for Dane County (United States Geological Survey Water-Supply Paper 1779-U,1965) indicates that regional groundwater flow in the vicinity of your property and the land fill could be flowing in a westerly direction. More recent unpublished information on file with the Wisconsin Geological and Natural History Survey indicates that regional groundwater flow could also be in a more northwesterly direction. In addition, water level measurements for monitoring wells installed in the unconsolidated deposits around the landfill indicate that shallow groundwater could be flowing in a more southerly direction. Based upon the fact that the assumed direction of shallow groundwater flow could be in a direction not directly toward the lot the Department has concluded that a variance could be granted. However, because of the proximity of some of the lots to the landfill, the wells will have to be provided with more casing than normally would be required at a site fully complying with the location requirements of s. NR 812.08 , Wis. Adm. Code. The Department emphasizes that while a variance from ch. NR 812, Wis . Adm. Code, requirements may be granted, compliance with ch. NR 812, Wis. Adm. Code Pried oo Recycled Paper
