Ambient Groundwater Quality Study
The Ambient Groundwater Quality Study began in 1999 to establish a baseline in water quality in the County and to track changes in water quality over time. From 1999 to 2003, the same set of bedrock wells completed in the Prairie du Chien Aquifer and the Jordan Aquifer were sampled for general chemistry and contaminants related to industrial processes, nitrate and pesticide use. In 2004, wells screened in the sand and gravel aquifer were added to the study. Below is a link to the report that covers the first five years of the study.
In 2004, our laboratory analysis by the United States Geological Survey showed levels of pesticides and nitrate of concern. A press release and frequently asked questions (FAQ) explain details about the study and its findings.
