The following private wells would be to any gP sampled P ed P rior Y soil <br /> disturbance at the subject property: <br /> • Jerry Olson, 6092 Highway 78 <br /> • Fred Beuthin, 10129 E. Mathenson Road <br /> • John Heintz, 10133 E. Mathenson Road <br /> • Heintz & Julson, 10147 E. Mathenson Road <br /> • Lar Dol Entrepreneurs, Inc., 10132 E. Mathenson Road <br /> Minor detections of VOCs have been identified downgradient of the Mazo Land <br /> Disposal Landfill. The landfill is located 1,700 feet directly north of the subject <br /> site. <br /> In compliance with CUP#1721, Yahara Materials will not store any bulk fuel at <br /> the subject site. Yahara Materials also intends to have on-site equipment fueled <br /> by a petroleum supplier. Because there will be no bulk storage of fuel or <br /> chemicals, we feel there is a low risk of groundwater becoming contaminated <br /> beneath the subject site. <br /> According to Dane County Land Conservation Service, the assessed property is <br /> underlain by a sandy loam (DkA) with rapid permeability. The majority of the <br /> land directly northwest of the subject site is also underlain with permeable sandy <br /> loam. Also there are a couple `fingers' of sandy loam with very rapid <br /> permeability located northwest of the subject site. These `fingers' of very rapid <br /> permeable sand located directly downgradient of the subject site and will prevent <br /> groundwater from flowing through the landfill. <br /> The majority of groundwater pumped from the on-site well will be used for <br /> wash water. This pumped groundwater will be collected on the southwest <br /> portion of the subject site in either a pond or a detention basin. This pumped <br /> groundwater will recharge the aquifer at the greatest distance from the landfill. <br /> Also, groundwater pumping at the subject site should not affect the capacity of <br /> any wells nearby. Yahara Materials is not going to export water off-site. <br /> Yahara Materials' restoration plan calls for ground contours that will direct all <br /> surface water to the southwest portion of the subject site. This redirected surface <br /> water will recharge the aquifer at the greatest distance from the landfill. <br /> Once the pumped groundwater and surface water has recharged the aquifer, it <br /> shall move towards the highly permeable `fingers' northwest of the subject site. <br /> This shall assure that groundwater is moving through the safest path, away from <br /> the landfill. <br />
