Response of Surface Water Chemistry to the Clean Air Act Amendments of 1990 (PDF) (92 pp, 4.9 MB, About PDF)
This 2003 report concludes that the regulations stemming from the Clean Air Act Amendments of 1990---including the Acid Rain Program regulations---have resulted changes in surface water chemistry in the northern and eastern U.S.  in response to changes in acid deposition. In addition, the report suggests that a market-based approach to pollution control works.
