Analyses of water collected at 32 sites on headwater streams in Pennsylvania during low-flow conditions in 1979-1980 were compared to pre-1971 data to evaluate whether acid rain had changed the chemistry of the streams in the previous decade. Most pH alkalinity, and sulfate values of the samples collected in 1979-1980 fell within the ranges of values for samples collected before 1971. The limited data indicate, however, that pH may have increased and alkalinity and sulfate may have decreased with time. 7 references, 10 figures, 5 tables.
