Hydrogeology of the Mogollon Highlands, central Arizona
John T.C. Parker, William C. Steinkampf, Marilyn E. Flynn
2005, Scientific Investigations Report 2004-5294
The Mogollon Highlands, 4,855 square miles of rugged, mountainous terrain at the southern edge of the Colorado Plateau in central Arizona, is characterized by a bedrock-dominated hydrologic system that results in an incompletely integrated regional ground-water system, flashy streamflow, and various local water-bearing zones that are sensitive to drought. Increased...

Production wells in the Westmoreland well field, Fair Lawn, Bergen County, New Jersey (the 'Fair Lawn well field Superfund site'), are contaminated with volatile organic compounds, particularly trichloroethylene, tetrachloroethylene, and 1,1,1-trichloroethane. In 1983, the U.S. Environmental Protection Agency (USEPA) placed the Westmoreland well field on its National Priority List of...
The drought of 1998-2002 in North Carolina — Precipitation and hydrologic conditions
J. Curtis Weaver
2005, Scientific Investigations Report 2005-5053
Drought conditions prevailed across much of North Carolina during 1998-2002, resulting in widespread record-low streamflow and ground-water levels in many areas. During this 4-year period, the drought was continuous in areas of western North Carolina, although eastern areas of the State had some periods of relief from tropical storms in...

Daryll A. Pope, Martha K. Watt
2005, Scientific Investigations Report 2004-5101
The New Jersey Department of Environmental Protection (NJDEP) Well Head Protection Program, developed in response to the 1986 Federal Safe Drinking Water Act Amendments, requires delineation of Well Head Protection Areas (WHPA's), commonly called contributing areas, for all public and non-community water-supply wells in New Jersey. Typically, WHPA's for public...
