U.S. Forest Service Water Quality Data

The U.S. Forest Service manages a large collection of air-quality-related water chemistry data. These datasets vary greatly in both spatial and temporal extent, ranging in geographic size from a single lake to large regions of the entire United States, and in time from a single sampling event to a 50-year monitoring effort. These datasets have been collected on Forest Service lands or by the Forest Service on adjacent lands, and are used to help assess air pollution impacts to sensitive waters in Federally-protected areas and more generally to help protect and enhance air quality in national wilderness areas and other locations of scenic, recreational, historic, or natural value. This page serves as a collection of links through which this water chemistry data can be accessed and explored.
