bacteria and nitrates on a yearly basis, and for arsenic at least once during the life of each well. Depending on the local geology and land use where your well is located, there may be other contaminants that you should test for too. Find out more by visiting our Private Well Testing web page.

Any water well and water system, whether deep or shallow, can become contaminated when flooding occurs. Water testing is the only way to know if your well is safe to drink.
Please see our document named "What should I do when my well floods" for additional information on this important topic.
The Iowa DNR Private Well Tracking System (PWTS) is used by county and state staff to track private well construction permitting, water testing, well renovations and well plugging.
The PWTS is designed as an authorized user type of data system for the purpose of Iowa's well program record keeping. The general public can create an account and view the information stored in the system.
GeoSam is Iowa’s geologic site and sample tracking program maintained by IIHR-Iowa Geological Survey.
GeoSam provides location, identification, and other key information about every available well, rock exposure, or site of geologic information in Iowa. GeoSam can be searched using either a map-based or text-based interface.
The GeoSam does not require a login to view information stored in the system.

NEW - GP6 Well Siting Tool
The Iowa DNR recently developed an online GP6 Well Siting Tool to assist landowners, well contractors, and engineers.
The tool is useful for performing desk evaluations of well sites and help determine if the well location will likely require discharge management through GP6. It also helps define which locations likely cannot support well construction discharge due to close proximity of Outstanding Iowa Waters (OIWs).
As a user of this tool, you have access to map layers that will help you identify distances to surface waters and OIWs, locations of sinkholes, karst areas, land slope, and more. It also allows you to print the map you create to use as a resource.
The GP6 Well Siting Tool works with Google Chrome and Mozilla Firefox web browsers. Currently, it is not compatible with Internet Explorer. To open and use the GP6 Well Siting Tool, click on the following link: https://programs.iowadnr.gov/maps/gp6/.
To learn more about GP6 and the resources available to help you comply, please click on the following link: www.iowadnr.gov/GP6.

This is a GIS based mapping system that allows you to view information about many of the permitted sites and other recorded sites around the state.
This website allows the public to search and find information about contaminated sites and print out results.
See the other Iowa DNR Private well Web pages for additional topics and information.
The State of Iowa requires any person manufacturing, storing, handling, transporting, or disposing of a hazardous substance to notify the department and local law enforcement of the occurrence of a hazardous condition.
The notification should be made as soon as possible but not later than six hours after the onset or discovery of the hazardous condition.
Local law enforcement is also required by Iowa Code to report a "Hazardous Condition" to the department within six hours.
If In Doubt… Report It!
The Iowa DNR Field Services and Compliance Bureau includes six field offices located throughout Iowa. They serve as a point of contact for questions about activities and problems related to environmental protection throughout the state. The focus of field office staff is helping citizens, business and industry achieve compliance with Iowa’s environmental programs. Our goal is to coach for compliance rather than collect penalties.
Field office staff conduct routine inspections at facilities permitted by the department and provide technical assistance to help people meet permit requirements. Staff investigate complaints from the public, and respond to spills of hazardous substances from a variety of sources.
