Methods of rating unsaturated zone and watershed characteristics of public water supplies in North Carolina Methods of rating unsaturated zone and watershed characteristics of public water supplies in North Carolina
Overlay and index methods were derived for rating the unsaturated zone and watershed characteristics for use by the State of North Carolina in assessing more than 11,000 public water-supply wells and approximately 245 public surface-water intakes. The rating of the unsaturated zone and watershed characteristics represents a practical and effective means of assessing part of the inherent

Susceptibility of ground water to surface and shallow sources of contamination, Orange County, North Carolina Susceptibility of ground water to surface and shallow sources of contamination, Orange County, North Carolina
In 1998, the relative susceptibility of ground water in Orange County, North Carolina,to contamination from surface and shallow sources was evaluated. A geographic information system was used to build three county-wide layers--soil permeability, land use/land cover, and land-surface slope. The harmonic mean permeability of soil layers was used to estimate a location's capacity to...

Estimated water use, by county, in North Carolina, 1990 Estimated water use, by county, in North Carolina, 1990
Data on water use in North Carolina were compiled for 1990 as part of a cooperative agreement between the U.S. Geological Survey and the Division of Water Resources of the North Carolina Department of Environment, Health, and Natural Resources. Data were compiled from a number of Federal, State, and private sources for the offstream water-use categories of public supply, domestic...
