More than 100 compounds are included in the Annual Water Quality Report. The compounds are measured and stated as parts per million which is the same as milligrams per liter. To put this in perspective, it means one pound of a substance in one million pounds of water or approximately one drop in ten gallons of water. Deep wells are confined by a layer of impervious material and are less susceptible to contamination as compared to shallow aquifers. The Madison Water Department staff performs hundreds of tests per year and also contracts with the State Department of Health Laboratory for testing which is beyond our limits due to the high cost of testing equipment that is used to detect various contaminants.

Drink at least 2 liters a day. The North Skunk Creek Aquifer starts north of Lake Herman and curves SE around the east side of the lake, is directly below the City of Madison, and encompasses lakes Madison and Brant, and Silver Creek. Lakes Madison and Brant and Silver Creek are actually where the aquifer comes to the surface of the ground. The Howard aquifer is not shown because it is more complex. Generally, it lies below Madison, Lake Herman, and Lake Madison, but not beneath Lake Brant, Chester, or other specific areas surrounding Madison.
