Expert Report on the Relationship Between Land Use and Stream Condition (as Measured by Water Chemistry and Aquatic Macroinvertebrates) In the Delaware River Basin

 800 532 Stroud Water Research Center

Stroud Water Research Center researchers were asked to provide evidence of the relationship between changes in land use and changes in stream quality. The Stroud Center’s data from hundreds of…

Review of Pennsylvania’s Proposed Water Quality Criteria for Chloride

 800 532 Stroud Water Research Center

Stroud Water Research Center researchers reviewed the Pennsylvania Department of Environmental Protection’s proposed water quality criteria for chloride. The proposed criteria are not protective of aquatic communities and should be…

Spatial and Temporal Variation in Water Quality Among Major Tributaries of the Schuylkill River
