What's In My Neighborhood? Agricultural Interactive Mapping


The Minnesota Department of Agriculture is the lead agency for response to, and cleanup of agricultural chemical contamination in Minnesota. Because of this role MDA has tracked spills of agricultural chemicals and sites contaminated with agricultural chemicals since the late 1970's. For the purpose of mapping these incidents MDA has categorized them into three categories 1. Old Emergencies, 2. Small Spills and Investigations, and 3. Investigations Boundaries. MDA has also made available information relating to any investigations that have been closed with contingencies attached to them.

  1. Old Emergencies: These points represent emergencies which were closed prior to March 1, 2004. These files and the locations plotted have not been reviewed for accuracy and completeness. The point located and the locational attributes provided are known to contain errors. Therefore, to be sure you have reviewed relevant Case Files, we suggest you review any Case Files where the point falls on or near your area of interest along with the sites identified on the County Spill Report referenced above. See Metadata.
  2. Smalls Spills and Investigations: These points represent the location of small spills and investigations, which were closed after March 1, 2004. Status and contact information is provided for each point. For more detailed information, review the Case File. See Metadata.
  3. Investigation Boundaries: These polygons represent the approximate extent of large spills and other types of facility investigations. Status and contact information is provided for each polygon. For more detailed information, review the Case File. See Metadata.

Facility Investigations are further subdivided into the following program areas:

  • Awaiting Prioritization Investigation files of known or potential agricultural chemical contamination that are waiting to be prioritized.
  • Prioritized Investigation files of known or potential agricultural chemical contamination that have been prioritized and are awaiting activation.
  • Comprehensive Facility Investigation / MERLA Investigation files of known or potential agricultural chemical contamination that have been activated in MDA's Comprehensive Facility Investigation Program or are active Superfund sites under MDA's oversight.
  • AgVIC Investigation files of known or potential agricultural chemical contamination that have enrolled in the MDA's Agricultural Voluntary Investigation and Cleanup (AgVIC) Program.
  • Agricultural Chemical Emergency Response Investigation files that were reported as emergency spills of agricultural chemicals and are large enough in size to be represented by a polygon.

Contingencies: These polygons represent areas with a soil or ground water contingency or restriction. For specific information about the types of contingencies we have used, see The MDA IRU Incident Case File Closure Documentation (PDF: 27 KB / 3 pages). The area included in the contingency is displayed here. Review the "Contingency Document" (there is a link to these PDF files available after you do an Identify) for the area and the Case File, to get specific information about the contingency. See Metadata.

In the future, we plan to add additional search capabilities to the site and we are in the process of adding polygon data for approximately 550 Abandoned Ag-Chem facilities, which were inventoried in 2004. If you have questions or comments regarding the data or the mapping application, please contact Gary Elsner at gary.elsner@state.mn.us or 651-201-6268.

How Do I search?

The Minnesota Department of Agriculture, Incident Response Unit, is the regulatory authority all Agricultural Chemical (Ag-Chem) Incidents in Minnesota. To find information about incidents in your area, you need to look at the following sources of information. For additional information read the "What's In My Neighborhood? - Agricultural" brochure (PDF: 213 KB / 2 pages)

  • Review the County Spill Report: This report includes most of the incidents reported for each county, prior to May of 2008. Because we do not have accurate locations for many of our old incidents, use the information on this report to determine if any of these sites are or may be relevant. You will need to review the actual case file for more detailed information. These sites are also mapped as Old Emergencies. You may also get this report by requesting it from the MDA Data Practices Records Manager at 651-201-6698 for the county you are interested in.
  • What's In My Neighborhood? Agricultural Interactive Mapping  : To review the incidents in your area of interest.
  • See Minnesota Pollution Control Agency - What's In My Neighborhood? for non-agricultural related properties that have already been investigated and cleaned up, or those currently enrolled in MPCA cleanup programs. Also included are properties that were suspected to be contaminated, but after investigation turned out to be clean.

How can I download data?

This data set includes all of the spill points and polygons on our map, along with a metadata file for information on what is contained in the data. The shapefile download includes files which can be used to display information on a map. You need Geographic Information System (GIS) software in order to use the shapefile to make maps or perform other geographic-based functions.
