Water Quality Assurance
Programs that test the quality of water in lakes, rivers, streams, underground aquifers and water supply wells upon which public water systems rely. The tests identify the type and quantity of controlled substances (pollutants), nutrients and suspended solids; and assess likely pollution sources and factors associated with agricultural practices, industrial processes and other human activities.
