Des Moines Water Works’ Source Water Assessment program identifies contaminants having an impact on the Raccoon and Des Moines River watersheds. While there are many businesses, industries, and activities that may impact our watershed, the following maps show some of the more common. Due to the large size of the Des Moines River watershed, it is divided into three sections for easier viewing: upper(Boone), middle(Des Moines), and lower(Ottumwa ). The Raccoon River watershed is shown in its entirety.
Agricultural Drainage Wells
Descriptive Name: Registered agricultural drainage wells
Description: Agricultural drainage wells (ADW) are required to be registered both with the Iowa Department of Natural Resources (IDNR), as a part of the 1987 Groundwater Protection Act, and with the U.S. Environmental Protection Agency (EPA), as a part of the Underground Injection Control Program. This coveragelocates the ADW's identified through owner registrations reported to the IDNR. ADW locations were computed from legal descriptions available and hand drawn locations on section maps. The Iowa Department of Agriculture and Land Stewardship performed field checking of location and function of each registered ADW and developed a database from this information. This information was used to update the ADW coverage.
