Water Resources Center
The University of California Center for Water Resources stimulates and supports water and water-related research both within and among the various academic departments and research organizations of the University. The broad research focus includes the conservation, development, management, distribution, and utilization of water resources with a view to the optimum present and future use.
Water Quality Program - Nitrate Groundwater Pollution Hazard Index
Purpose: To provide information for farmers to voluntarily target resources for management practices that will yield the greatest level of reduced nitrogen contamination potential for groundwater by identifying the fields of highest intrinsic vulnerability.
How it Works: The index works with an overlay of soil, crop, and irrigation information. Based on the three components, an overall potential hazard number is assigned and management practices are suggested where necessary. If you don't know what soil type you have, try this online soil survey with detailed soil survey data for much of California, Arizona, and Nevada.
