In summer of 1999, the Northumberland County Conservation District was awarded a grant totaling $114,700 by the PA Department of Environmental Protection 319 Program. This total includes matching funds and in-kind services from the US Geological Survey, Bucknell University, and the SCRA.
The USGS team was led by Dr. Charles Cravotta, a hydrogeochemist with considerable experience in mine drainage and its treatment. Dr. Carl Kirby led the Bucknell University efforts. Dave Moratelli and Steve Ulceski administered the grant for the Nothumberland County Conservation District.
The overall objective was to characterize
the chemistry and flow of mine discharges and selected stream sites within the
watershed. The data were entered into a geographical
information system (GIS) database developd by Carl Kirby and Bucknell students
to allow the data to be analyzed in a systematic fashion. This study goes a
long way toward developing a comprehensive plan for the watershed.
