Rupert, M.G., 2003, Raster dataset showing the probability of elevated concentrations of nitrate in ground water in Colorado, hydrogeomorphic regions included and fertilizer use estimates not included: U.S. Geological Survey data release, https://doi.org/10.5066/P9ZMI872.

Summary

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This dataset is one of eight datasets produced by this study. Four of the datasets predict the probability of detecting atrazine and(or) desethyl-atrazine (a breakdown product of atrazine) in ground water in Colorado; the other four predict the probability of detecting elevated concentrations of nitrate in ground water in Colorado. The four datasets that predict the probability of atrazine and(or) desethyl-atrazine (atrazine/DEA) are differentiated [...]

Purpose

Draft Federal regulations (U.S. Environmental Protection Agency, Pesticides and Ground Water State Management Plan Regulation; Proposed Rule, U.S. Federal Register, v. 61, no. 124, June 26, 1996, p. 33260-33301) may require that each State develop a State Pesticide Management Plan (PMP) for the herbicides atrazine, alachlor, metolachlor, and simazine. The Colorado Agricultural Chemicals and Groundwater Protection Program--a cooperative effort of the Colorado Department of Agriculture (CDA), the Colorado Department of Public Health and Environment (CDPHE), and the Colorado State University Cooperative Extension (CSUCE)--is developing a PMP for each of the herbicides and would benefit from a map that could be used to predict the probability of detecting atrazine and DEA in ground water. The map could be incorporated into the PMP and provide a sound hydrogeologic basis for atrazine management in Colorado. Other organizations and programs that could benefit from maps that predict the probability of detecting atrazine, DEA, and elevated concentrations of nitrate in ground water include the agri-chemical industry, county and city governments, farmers, planning and zoning commissions, education programs for applicators, and State programs related to Wellhead Protection, Drinking Water, Home-A-Syst, and Best Management Plans (BMP's). To address these needs, the U.S. Geological Survey (USGS), in cooperation with the CDA, CDPHE, and CSUCE, conducted a study to develop maps to predict the probability of detecting atrazine and(or) DEA and elevated concentrations of nitrate in ground water in Colorado.
