McLeod County Well Testing Maps
When building or purchasing property that has, or will have a well, you may want to have the water tested. The 3 water tests most frequently done are coliforms, nitrates and arsenic. Coliforms and nitrates may indicate a problem with the location of the well. Arsenic is a known carcinogen and a naturally occurring element in many of the wells in McLeod County. There are water treatment systems available to remove arsenic from the water. The EPA arsenic standard for safe drinking water is 10 parts per billion (ppb). Nitrates need to be below 10 parts per million (ppm). Coliform should not be present in drinking water which is a 0 CFU/100 ML. More information can be obtained from Environmental Services, Public Health and Zoning Offices in the County.
