Pesticide-sampling equipment, sample-collection and processing procedures, and water-quality data at Chicod Creek, North Carolina, 1992
Water-quality samples were collected from Chicod Creek in the Coastal Plain Province of North Carolina during the summer of 1992 as part of the U.S. Geological Survey's National Water-Quality Assessment Program. Chicod Creek is in the Albemarle-Pamlico drainage area, one of four study units designated to test equipment and procedures for collecting and processing samples for the solid-phase extrac

Irrigation water supply and demand data for 1976, 1980, and 1984 for the western San Joaquin Valley, California
This report presents the irrigation water supply and demand data for 1976, 1980, and 1984 for 32 water districts in the western San Joaquin Valley, California. Data are provided for each water district or each of the three years if the data were available. The complete data base is given by water district or each township, range, and section in the rectangular system for the subdivision of public

Effect of the restricted use of phosphate detergent and upgraded wastewater-treatment facilities of water quality in the Chattahoochee River near Atlanta, Georgia
Data compiled for the six largest waste-water treatment facilities in Metropolitan Atlanta, Georgia, indicate about an 83-percent reduction in the phosphorus load discharged to the Chattahoochee River from 1988 to 1993 because of restricted use of phosphate detergents and upgraded treatment of municipal wastewater. This reduction resulted in about a 54-percent decrease in the phosphorus load in th

National Water-Quality Assessment (NAWQA) Program, Long Island-New Jersey (LINJ) Coastal Drainages Study Unit
In 1991, the U.S. Geological Survey (USGS) began its National Water-Quality Assessment (NAWQA ) program to (1) document the quality of a large, representative part of the Nation's water resources; (2) define water-quality trends; and (3) identify major factors that affect water quality. In addressing these goals, the program will produce information that will be useful to water policy makers and m

National Water-Quality Assessment (NAWQA) Program, Long Island-New Jersey (LINJ) Coastal Drainages Study Unit : Scope of the Long Island-New Jersey Coastal Drainages Study-Unit investigation
Scope of the Long Island-New Jersey Coastal Drainages Study-Unit InvestigationIn 1991, the U.S. Geological Survey (USGS) began a National Water-Quality Assessment (NAWQA) Program to document the status of and trends in quality of a large representative part of the Nation's water resources and to provide a sound scientific understanding of the primary natural and human factors that affect the quali

Effects of reservoirs on flood discharges in the Kansas and the Missouri River basins, 1993
The floods of 1993 were of historic magnitude as water in the Missouri and the Mississippi Rivers reached levels that exceeded many of the previous observed maximums. Although large parts of the flood plains of both rivers upstream from St. Louis, Missouri, were inundated, water levels would have been even higher had it not been for the large volume of runoff retained in flood-control reservoirs.

Major ions, nutrients, and trace elements in the Mississippi River near Thebes, Illinois, July through September 1993
Extensive flooding in the upper Mississippi River Basin during summer 1993 had a significant effect on the water quality of the Mississippi River. To evaluate the change in temporal distribution and transport of dissolved constituents in the Mississippi River, six water samples were collected by a discharge-weighted method from July through September 1993 near Thebes, Illinois. Sampling at this lo

Summary of selected computer programs produced by the U.S. Geological Survey for simulation of ground-water flow and quality, 1994
A summary list of reports that document numerical methods that simulate ground-water flow and quality is presented. The list documents the reference by giving a description of each model program, its numerical features, an expression of the number of past applications and where to obtain a copy. All reports included in the list have been published or developed by the U.S. Geological Survey and mos

Simulation of unsteady flow in the Roanoke River from near Oak City to Williamston, North Carolina
A one-dimensional, unsteady-flow model was calibrated, validated, and applied to a 30.4-mile reach of the Roanoke River between State Highway 42-11 bridge near Oak City (river mile 67.0) and the U.S. Highway 17-13 bridge at Williamston (river mile 36.6) North Carolina. The model was calibrated and validated for flows ranging from about 2,000 to 12,000 cubic feet per second. The model was used to c

Effects of sediment depositional environment and ground-water flow on the quality and geochemistry of water in aquifers in sediments of Cretaceous age in the coastal plain of South Carolina
The quality and geochemistry of ground water are significantly affected by the depositional environment of aquifer sediments. Cretaceous sediments in the Coastal Plain of South Carolina have been deposited in fluvial, delta-plain, marginal-marine, and marine environments. Depositional environments of sediments within a single aquifer may grade from nonmarine, fluvial, or upper delta plain near the

Saltwater movement in the upper Floridan aquifer beneath Port Royal Sound, South Carolina
Freshwater for Hilton Head Island, South Carolina, is supplied by withdrawals from the Upper Floridan aquifer. Freshwater for the nearby city of Savannah, Georgia, and for the industry that has grown adjacent to the city, has also been supplied, in part, by withdrawal from the Upper Floridan aquifer since 1885. The withdrawal of ground water has caused water levels in the Upper Floridan aquifer to
