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.
