Assessments of Aquifer Sensitivity on Navajo Nation and Adjacent Lands and Ground-Water Vulnerability to Pesticide Contamination on the Navajo Indian Irrigation Project, Arizona, New Mexico, and Utah

Blanchard Paul, United States Geological Survey

This USGS report is an assessment of aquifer sensitivity on the Navajo Nation and ground-water vulnerability to pesticide contamination. The topics include an introduction that covers this project's purpose and scope, geohydrologic setting, and a review of selected, previously used assessment methods. Other topics covered are the methods developed for assessment of the geology, precipitation, soil properties, slope of the land surface, and stream courses of the area, results of assessments of aquifer sensitivity, and the method developed for and results of assessment of ground-water vulnerability. Also embedded in this report are figures, tables and an appendix related to the topics.
