Abstract
As part of the U.S. Geological Survey’s National Water-Quality Assessment program, the effects of urbanization on the water quality and ecology of streams throughout the United States are being studied. These studies are examining a range of physical, chemi-cal, and biological changes that occur in streams as hu-man populations increase in watersheds and land uses are converted from rural to urban. As part of one of these investigations, thirty streams were selected along a gra-dient of increasing urban intensity in the Piedmont Eco-region of Georgia and Alabama, specifically in the vicin-ity of Metropolitan Atlanta, Georgia. Fixed interval and synoptic sampling of stream water will be conducted for a period of 1 year and will include measurement of Es-cherichia coli (E. coli) bacteria levels, pesticides, major ions, alkalinity, pH, dissolved oxygen, and specific con-ductance. Water temperature and stream stage will be monitored continuously using data loggers. Stream geo-morphic and habitat features, as well as stream biological communities, will be characterized during spring and summer 2003. Data collection for this project began dur-ing October 2002 and will continue through October 2003.
