Paperback. Condizione: New. Print on Demand. This book presents the findings of the 1991 DRBC/NPS Scenic Rivers Water Quality Monitoring Program. Conducted in the Upper and Middle Delaware Scenic and Recreational Rivers, the program monitors water quality in these rivers and over 70 tributaries. Begun in 1984, the program employs strict quality assurance, and has several ongoing special investigations which have examined topics such as sediment toxics in Beaver Brook. The authors present monitoring data for 77 sites, and examine observed trends related to urbanization.

The book provides data and insights relevant to water quality management and environmental protection.
