Screening methods for groundwater pollution potential from pesticide use in Colorado agriculture
The project evaluates the use of two models for predicting groundwater pollution potential under conditions typical of Colorado agriculture. The two models evaluated in the project are a solute transport model called CMLS and a hydrologic index for ranking relative pollution potential called DRASTIC. The models were used to determine which pesticides had the highest potential for leaching to the groundwater and which areas had the greatest likelihood for groundwater contamination. Results were also used to assess the relative importance of hydrogeologic factors, agricultural management factors and the characteristics of the individual pesticides in determining pollution potential. The San Luis Valley, located in south-central Colorado, was used as a case study for the project.
