Program for evaluating stream quality in North Carolina
The design and objectives of the program for evaluating stream quality in North Carolina are described. Using water-quality and streamflow data collected since the 1940's, a study is underway to define certain variations in water quality, to quantify the effects of man 's activities on water quality, and to determine long-term trends at key locations on the State 's major river. Data collected from 47 unpolluted stream sites were used to estimate average concentrations for naturally occurring constituents during periods of high and low flow. Methods are described for estimating constituent loads derived from both natural sources and sources of pollution. (Woodard-USGS)
Water resources of northeast North Carolina
Several water-related problems are associated with economic development of northeast North Carolina. The solution to these problems depends in part on adequate knowledge of the hydrology of this 8,930 square mile coastal area. Average annual precipitation on the area is about 50 inches. Of this amount, about 34 inches returns to the atmosphere by evapotranspiration, about 15 inches leaves the area as runoff, and about one inch leaves through ground-water outflow. No large stream originates within the area, but major streams entering from the north and west bring in three times as much streamflow as originates within the study area. The flat, low-lying terrane does not offer opportunities for extensive development of surface-water supplies through the use of reservoirs. Much of the surface water is contaminated by saltwater from the ocean. Ground water occurs in three major aquifers, all of which contain both freshwater and saltwater.
Summary of data on chemical quality of streams of North Carolina, 1943-67
This report summarizes water-quality data collected by the U.S. Geological Survey in cooperation with the State of North Carolina during the period 1943-67. Maximum, minimum, and average values are shown for complete analyses of mineral constituents dissolved in water from 177 locations at which samples were collected daily or monthly for at least 1 consecutive year. Maximum and minimum values are given for 460 'miscellaneous and occasional stations' at which two or more chemical analyses were made. Single analyses are shown for 580 additional sampling sites. A total of about 19,000 analyses were used in determining statistical values included in the report. Water in streams of North Carolina is generally of good mineral quality and is acceptable with a minimum amount of treatment for most uses.
Ground-water supply of Cape Hatteras National Seashore recreational area, North Carolina, Part 4
In 1957, the National Park Service requested that the U. S. Geological Survey determine the quality and quantity of available ground water at selected sites within the Cape Hatteras National Seashore Recreational Area. A series of reports, Ground-Water Supply of Cape Hatteras National Seashore Recreational Area" by P. M. Brown (1960), "Ground-Water Supply of Cape Hatteras National Seashore Recreational Area, Part 2" by J. 0. Kimrey (1960), and "Ground -Water Supply of Cape Hatteras National Seashore Recreational Area, Part 3" by W. H. Harris and H. B. Wilder (1964), have been prepared and transmitted to the National Park Service in compliance with their request.
