Title:
Final Nitrate-Nitrogen Conditions in Private Wells Township Testing Results
Abstract:
The Minnesota Department of Agriculture (MDA) has designed a Township Testing Program to determine nitrate-nitrogen conditions in private wells. Townships are initially selected if 30% of the township is vulnerable to groundwater contamination and 20% is in row crop production. The MDA uses the results to prioritize future work to address nitrate concerns, as described in the Nitrogen Fertilizer Management Plan (NFMP).
Purpose:
This layer contains the final testing results by township. The initial results include data from all wells initially tested regardless of well construction or nitrogen source. Final results are determined using two rounds of sampling and a process to remove wells with construction concerns, insufficient construction information and those near potential non-fertilizer sources of nitrate. In many cases wells have been removed from the final dataset because homeowners didn’t participate in the second round of testing. Final results represent wells that are potentially impacted by a fertilizer source. MDA considers <20 wells inadequate to characterize a township for the purposes of the NFMP and is denoted with <20 wells instead of a percentage.
Detailed sampling results are available at: www.mda.state.mn.us/townshiptesting.
