Due to elevated levels of nitrate-nitrogen, the Sundsruds Court Mobile Home Park Drinking Water Supply Management Area (DWSMA) has been listed at a Mitigation Level 2 under the Groundwater Protection Rule. To learn more about the determination process visit Mitigation Level Determination.
- Designated a Mitigation Level 2 on January 15, 2024 using the following criteria
- One or more public wells have exceeded 8 mg/L nitrate within the past 10 years
- No point source of nitrate found to be the cause of the elevated nitrate level
(i.e., ag chemical incidents, animal feedlots, improperly sealed wells, etc.)
- The DWSMA is approximately 310 acres (high vulnerability area)
- There are two cropland owners and operators within the DWSMA
- Located in Hubbard County
- There is one community well that has tested above 10 mg/L in the past ten years
Local Advisory Team
The MDA established a Local Advisory Team (LAT), consisting of local farmers and agronomists.
The primary functions of the LAT are to:
- Advise the MDA on the appropriate nitrogen fertilizer best management practices (BMPs) for the project area.
- Explore opportunities to use Alternative Management Tools (AMTs) in targeted high-risk areas.
- Provide the MDA with guidance on the most effective methods to communicate with the agricultural community in the local project area.
- Support the implementation of the BMPs and AMTs at the local level.
Throughout 2024 and 2025, MDA staff met with the Sundsruds Court LAT reviewing agronomic information and the MDA’s analysis of nitrogen loss below cropland within the DWSMA. Below is a list of milestones that were met during this process. The LAT will continue to meet once annually to review new public well nitrate data and discuss ongoing implementation of BMPs and AMTs within the DWSMA.
Status of the Sundsruds Court Mobile Home Park DWSMA LAT
- Formed a local advisory team
- The team is actively meeting
- Interviewed local farmers to gather information on the current nitrogen fertilizer management practices within the DWSMA
- Mapped the boundaries of cropland within this DWSMA
- Completed computer modeling of nitrate loss below the crop rooting zone within this DWSMA
- In consultation with the LAT, a list of BMPs and AMTs that are practicable and appropriate for protecting groundwater within this DWSMA was developed and approved by the MDA.
