Guidelines and standard procedures for continuous water-quality monitors: Site selection, field operation, calibration, record computation, and reporting
The U.S. Geological Survey uses continuous water-quality monitors to assess variations in the quality of the Nation's surface water. A common system configuration for data collection is the four-parameter water-quality monitoring system, which collects temperature, specific conductance, dissolved oxygen, and pH data, although systems can be...
