Groundwater serves a number of critical functions in Carver County. Perhaps most importantly, all drinking water in Carver County comes from groundwater sources. With a growing population, adequate groundwater supplies are increasingly important to support population and economic needs.

Groundwater also is important to critical natural resources in Carver County. Seminary Fen is a delicate and rare resource dependent on groundwater that provides natural habitat and incalculable water management benefits for our community. Natural resources like the Seminary Fen need to be protected for their critical links to the greater ecosystem, recreational opportunities, and contributions to Carver County’s unique natural amenities.

Groundwater Plan

In 2015, the County Board approved an updated Groundwater Plan. This plan defines the County’s role in groundwater resource management for the next ten years through identification goals and actions the County will take over the life of this plan.

The three overarching goals in this plan seek to protect groundwater quality, groundwater supply, and groundwater dependent natural resources in order to meet today’s needs without compromising future availability of this critical resource.

Groundwater Maps

As part of the Carver County Geologic Atlas, the Minnesota Department of Natural Resources developed a series of groundwater maps for the county.  These maps show groundwater aquifers, direction of groundwater flow, age of groundwater, pollution sensitivity, bedrock, sediment beneath the land surface, depth to bedrock and aggregate resources.  Digital copies of these maps can be found on the MN Department of Natural Resources Carver County Geologic Atlas site. 

Private well testing

Public water systems are tested regularly for a variety of contaminants; for private wells, regular testing is up to the well owner. Learn about private well testing.

Well sealing cost share program

Carver County offers well sealing cost share to qualified Carver County residents and or property owners to help seal unused wells. Unused wells, that are not properly sealed, pose a safety, health, and environmental threat to families and communities and a potential legal risk to the property owners. Such wells can act like a drain, allowing surface water runoff and pollutants, contaminated water, or improperly disposed waste a direct pathway into groundwater aquifers.

Learn about eligibility and download an application for well sealing cost share.

Minnesota state law requires that wells posing such risks be sealed by a Minnesota Department of Health licensed contractor.

If you are unsure an abandoned well exists on your property, please contact Tim Sundby at 952-361-1816 for assistance.
