Title: ROE Acid-Sensitive Waters
Abstract: The polygon dataset represents areas with acid-sensitive waters in the contiguous United States. Summary data in this indicator were provided by EPA’s Office of Atmospheric Programs and are taken from a publication documenting how surface waters have responded to reduced air emissions of acid rain precursors (U.S. EPA, 2003) and from more recent unpublished results (U.S. EPA, 2014). Trends are based on data collected in two networks: the TIME project and the LTM project. Because both networks are operated by numerous collaborators in state agencies, academic institutions, and other federal agencies, the monitoring data are not available in a single publication or database. The trend data in this indicator are based on observations documented in several publications (see pages 15-17 of U.S. EPA, 2003).
Purpose: These data were created to be used for the U.S. Environmental Protection Agency's Report on the Environment website.
