Scott Ator
Scott Ator is a Hydrologist at the USGS MD-DE-DC Water Science Center.
I have been a hydrologist with the U.S. Geological Survey in Baltimore, Maryland since 1994, including a Research Hydrologist from 2005 through 2010. My work has focused primarily on the design, implementation, and analysis and interpretation of results of water-quality and geochemical studies (including major-ion chemistry, nutrients, and pesticides) in streams and groundwater at multiple spatial

A regional assessment of water quality in small streams was conducted within four areas of distinct physiography and lithology in the upper Potomac River Basin. The Potomac River is a major tributary to the Chesapeake Bay, and this study provides new insight on the relationships between nutrient concentrations in small streams and watershed characteristics within this river basin.

Data from more than 850 sites were compiled and analyzed to document the occurrence of nitrate and pesticides in ground water of the Mid-Atlantic region as part of the Mid-Atlantic Integrated Assessment program of the U.S. Environmental Protection Agency. Only those data collected by the U.S. Geological Survey as part of regional networks between October 1985 and September 1996 (inclusive) were usAuthorsScott W. Ator, Matthew J. FerrariPesticides in surface water of the Mid-Atlantic region
Water-quality data from 463 surface-water sites were compiled and analyzed to document the occurrence and distribution of pesticides in surface water of the Mid-Atlantic region as part of the Mid-Atlantic Integrated Assessment program of the U.S. Environmental Protection Agency. Those data collected by the U.S. Geological Survey from October 1973 through March 1997 were used in the analyses. DataAuthorsMatthew J. Ferrari, Scott W. Ator, Joel D. Blomquist, Joel E. DysartRadon in ground water of the lower Susquehanna and Potomac River basins
Ground-water samples collected from 267 wells were analyzed for radon as part of a water-quality reconnaissance of subunits of the Lower Susquehanna and Potomac River Basins conducted by the United States Geological Survey (USGS) as part of the National Water-Quality Assessment (NAWQA) program. Radon is a product of the radioactive decay of uranium. Airborne radon has been cited by the Surgeon GenAuthorsBruce D. Lindsey, Scott W. AtorNitrate in ground water in the Great Valley carbonate subunit of the Potomac River Basin
Agriculture is the major land use in the carbonate part of the Great Valley of the Potomac River Basin. Applied fertilizer and manure are potential sources of nitrate that can contaminate Groundwater. Nitrate concentrations in Groundwater increased with increasing percentage of cropland but did not decrease with increasing well depth, as has been found in previous studies elsewhere.
