Nitrogen and Phosphorus Concentration Thresholds toward Establishing Water Quality Criteria for Pennsylvania, USA

Autor: John W. Clune, J. Kent Crawford, Elizabeth W. Boyer

Publikováno v: Water, Vol 12, Iss 12, p 3550 (2020)

Nutrient enrichment is currently a leading cause of impairment to streams in Pennsylvania. Evaluating the water quality condition and eutrophic status of streams and rivers is a challenge without established thresholds for nutrient concentrations, wh

Differential effects of land use on nutrient concentrations in streams of Pennsylvania

Autor: John W. Clune, William T Chappell, Elizabeth W. Boyer, J. Kent Crawford

Publikováno v: Environmental Research Communications. 2:115003

Nutrient pollution of surface waters is a widespread problem, calling for regional assessments of water quality conditions. In this study, we quantified long-term median nutrient concentrations of total nitrogen (TN) and total phosphorus (TP) in stre
