A general acidification hypothesis was described as a sequential process in three steps: (1) Sulfur deposition increases; (2) Sulfate concentrations in streams and lakes increase; (3) concentrations of protolytic and nonprotolytic cations increase. The increases in protolytic cations cause decreases in stream and lake alkalinity. The Panel discussed eight questions posed by EPA. Some of those were: Have lakes and streams become more acidic over the last 15 years. To what extent have lakes and streams been acidified by acid deposition as opposed to other factors. What processes control surface water acidity. Are monitoring programs appropriate and warranted for detecting changes that might take place.
