This project compares the current state of 11 Bucks County, Pennsylvania streams with data collected from 1968-1971, before the Clean Water Act went into effect. Research comparisons will document whether the ecological condition of these streams has improved due to mandated reductions in point-source pollution discharges, deteriorated as a result of watershed development in Bucks County, or remained the same over time.
