Utah State University\u27s Cooperative Extension Service has placed high priority on a Water Quality Initiative for Utah. As a part of that emphasis, a research project was initiated to analyze the hazards that agricultural chemicals pose to Utah\u27s ground water.

This report summarizes data on the use of pesticides on Utah\u27s major crop
