Emerging acid deposition research and monitoring issues

- EPA Acid Rain Division, Washington, DC (United States)
The research baselines established for acid rain in the 1980s position scientists and policy makers to evaluate the environmental effectiveness of the acid rain control program and to test the variety of scientific hypotheses made regarding the chemical, transport and biological processes involved in acidic deposition. Several new research questions have evolved. How effective are the emissions reductions? What is the residual risk? How have ecological recovery rates been affected and what other environmental factors influence recovery? What are the critical requirements to measure ecological change including the extent and rate while also capturing the extent and severity of emerging ecological stressors (such as watershed nitrogen saturation)? These and other questions are currently being synthesized within and outside of EPA to develop a long-term strategy to provide guidance to emerging research and monitoring issues.
