Surface- and ground-water quality data at selected landfill sites in Mecklenburg County, North Carolina, 1980-86
The U.S. Geological Survey initiated an urban water quality study in 1979 in cooperation with the City of Charlotte and Mecklenburg County, North Carolina, to study, among other things, the effects of solid waste disposal on the water quality in Mecklenburg County. Water quality samples (747 inorganic and 168 organic) were collected at 20 surface water sites and 53 monitoring wells at four selecte

Hydrologic and geologic data for the Edwards Aquifer Recharge Zone near Georgetown, Williamson County, Texas, 1986-87
This report presents a compilation and summary of data related to the interchange of water between the Edwards aquifer and streams, and to the hydraulics of vertical movement of water in the Georgetown Limestone in the Georgetown area of Williamson County. It presents hydrologic, geologic, hydraulic, physical, geophysical, and water-quality data collected from selected wells and stream sites in th

Organochlorine chemical residues in bluegills and common carp from the irrigated San Joaquin Valley floor, California
Samples of bluegills (Lepomis macrochirus) and common carp (Cyprinus carpio) collected from the San Joaquin River and two tributaries (Merced River and Salt Slough) in California were analyzed for 21 organochlorine chemical residues by gas chromatography to determine if pesticide contamination was confined to downstream sites exposed to irrigated agriculture, or if nonirrigated upstream sites were

Theory, construction and operation of simple tensiometers
The tensiometer, introduced by Richards and Gardner (1936) has been a tool often ignored in unsaturated zone investigations. Hazardous waste disposal studies that require values of unsaturated zone matric potentials will expand tensiometer use. Familiarity with operation and installation principles is necessary to ensure quality data collection.The essential elements of a tensiometer are a porous

Use of borehole neutron logs to estimate moisture content in the unsaturated zone of an alluvial aquifer
he neutron borehole logging tool was calibrated for the determination of moisture content in theunsaturated zone of an alluvial aquifer. A continuous core sample was collected to a depth of 15 ft from the unsaturated zone.Moisture content and other soil properties were determined by standard soil-laboratory techniques. The neutron logs profile was correlated to moisture content. The first correlat

Calculation of solar radiation in mountainous terrain
A study was performed to assess the accuracy of a daily solar radiation model for horizontal or sloping sites in terrain where surrounding ridges and tall trees block both direct beam and diffuse sky short wave radiation. To simulate adequately the major effects of these environments on radiation, the model incorporated (1) standard treatment of solar geometry (after Harris, 1983); (2) separation
