    dct:description "This U.S. Geological Survey Data Release contains the associated data described in the Scientific Investigations Report, \"Trends in water quality of selected streams and reservoirs used for water supply in the Triangle area of North Carolina, 1989-2013\". Since 1989, the U.S. Geological Survey and a consortium of local governments have tracked water-quality conditions and trends in the water-supply reservoirs and streams in the Triangle area of North Carolina located within the upper Cape Fear and Neuse River Basins. Temporal trends in water-quality were analyzed for thirteen stream and eight reservoir sites. Seventeen water-quality parameters and constituents were examined at these sites" ;
