Ground water vulnerability mapping. Research technical completion report. Contract No. 5938/QC004100 Item Info

Protecting Idaho's ground water by predicting the vulnerability of ground water to contamination is the primary goal of the mapping system described in this report. It continued work begun in the late 1980s to assess the vulnerability of ground water of the Snake River Plain aquifer in southern Idaho (Rupert et al. 1991). There were three main tasks in this study. The first task was to apply the rating system developed by Rupert et al. (1991) to other types of aquifers in Idaho. The second task was to perform a verification of the rating system for its validity and reliability. The third task was to map the components of ground water vulnerability at a scale of 1:24,000, modifying the vulnerability assessment method as necessary. An area in western Jerome County was chosen for examination and mapping at that scale. In task one, the Rupert rating system was applied to the Rathdrum Prairie aquifer in northern Idaho, to the Big Wood River-Silver Creek aquifer in south central Idaho, to a portion of the Snake River Plain aquifer near Burley, and to the Jerome County study area. In task two, a statistical analysis was performed on the application of the rating system to each of the aquifers as well. The results of tasks one and two are reported in the section, "Application and Analysis of Rupert et al. Rating System." The results of task three, mapping at a scale of 1:24,000, are presented in the "Jerome Pilot Project" section. The last section of the report, "Conclusions and Recommendations" summarizes what has been learned in the two studies and makes recommendations for future approaches to groundwater vulnerability mapping. Submitted to Idaho Department of Health and Welfare, Division of Environmental Quality.
