ABSTRACT Goodrow, S.M.; Procopio, N.A.; Korn, L.; Morton, P.; Schuster, R.; Pang, H.; Kunz, C.; Ingelido, P., and Heddendorf, B., 2017. Long-term temporal water-quality trends within the Barnegat Bay watershed, New Jersey. In: Buchanan, G.A.; Belton, T.J., and Paudel, B. (eds.), A Comprehensive Assessment of Barnegat Bay–Little Egg Harbor, New Jersey. This regional water-quality assessment compiles and analyzes water-quality data within the Barnegat Bay watershed (Ocean County, New Jersey) to determine if significant changes and trends occurred over decadal spans. Data evaluated spanned from the 1970s through July of 2013. Trends were evaluated after regionalizing sampling locations into 17 geographic zones. Over 1700 sampling stations within freshwater and Bay zones provided over 280,000 data results for 20 parameters. The parameters evaluated include: temperature, salinity, dissolved oxygen (DO), pH, nutrients, indicator bacteria, and solids. Temperature data comparing the 1970s with the present show st...
