Summary The Long-Term Monitoring Network (LTM) is funded by the U.S. Environmental Protection Agency (EPA) to monitor trends in surface water quality by nesting a few intensively-monitored stations within a network of more numerous but less frequently sampled stations. The intensively-monitored stations have provided monthly discharge and water-quality data at 6 locations across the country since 1983. Continuous discharge and storm water quality sampling were added to these stations in the late 1980’s. One of the major objectives of the Clean Air Act Amendments (CAAA) was to establish a network of stations for long-term monitoring of surface-water quality and to determine its relation to changes in atmospheric...
