Occurrence and Distribution of Pesticides and Volatile Organic Compounds in Ground Water and Surface water in Central Arizona Basins, 1996-98, and Their Relation to Land Use
The National Water-Quality Assessment (NAWQA) program begun by the U.S. Geological Survey (USGS) provided the opportunity to assess the occurrence and distribution of organic and inorganic compounds in the water resources of central Arizona during 1996-1998. The objectives of the NAWQA program are to describe the current water-quality conditions and trends in rivers, streams, and ground water and to understand the natural and human factors that affect the conditions and trends in water quality throughout the Nation. The Central Arizona Basins (CAZB) study area was one of more than 50 study areas across the United States that were selected to help meet these objectives
