The impact of a 4"well pumping 25 gpm for domestic uses and irrigation of the <br /> resident property has very little impact. The Water Well Industry that service our City has not found the <br /> private wells have changed the water level on a permanent or seasonal uses. Changes in the static <br /> water levels seasonally could be in inches and could be seen on private well drop pipe (pump supply <br /> pipe) but none has been noticed. <br /> It is for this reason the Minnesota Department of Health Well Management Unit as well as the <br /> Department of Natural Resources have not bothered dealing with wells that pump under 10,000 gallons <br /> per day or 1 million gallons per year. <br /> Residential areas to the South and South West have numerous residential wells (one per house)with no <br /> impact on each other. Cone of depression for any well will exist but at 25 gpm may not be detectable 5 <br /> feet away from the well. <br /> Wells in the area are mostly finished in the sedimentary sandstone call Franconia-Ironton <br /> Galesville now call the "Tunnel City". A smaller portion of wells are finished in the glacial gravels. The <br /> glacial gravels are somewhat protected by an up-flow from the Tunnel City into the glacial gravels <br /> above. <br /> Your twelve wells will not have a measurable impact on other wells in the area or for other City <br /> users near Trott Brook as circled. <br /> Raymond T.
