The National Atmospheric Deposition Program has measured long-term trends in acidic wet deposition since 1978. Over the past thirty-plus years, most of the continental United States has experienced significant trends in ion species affecting acidic deposition. Some of these trends appear directly attributable to the 1990 Clean Air Act Amendments.
