The hydrogeologic framework and a reconnaissance of ground-water quality in the Piedmont Province of North Carolina, with a design for future study The hydrogeologic framework and a reconnaissance of ground-water quality in the Piedmont Province of North Carolina, with a design for future study
The U.S. Geological Survey is investigating the relation of ground- water quality and land use in the regolith and fractured rock ground-water system of the North Carolina Piedmont. The initial phase of this study provides a description of the ground-water flow system and a review of available ground-water data and formulates hypotheses that guide the design of a water-quality monitoring...

Approximate water-level changes in wells completed in the Chicot and Evangeline aquifers, 1977-89 and 1988-89, and measured compaction, 1973-89, in the Houston-Galveston region, Texas Approximate water-level changes in wells completed in the Chicot and Evangeline aquifers, 1977-89 and 1988-89, and measured compaction, 1973-89, in the Houston-Galveston region, Texas
This report presents data on water-level changes in the Chinot and Evangeline aquifers during 1977-89 and 1988-89 and data on measured compaction during 1973-89. Measurements of water level in 307 wells were used to construct the maps showing water-level changes. Compaction data were obtained from 12 wells equipped with compaction monitors at 11 sites.

Hydrologic environments and water-quality characteristics at four landfills in Mecklenburg County, North Carolina, 1980-86 Hydrologic environments and water-quality characteristics at four landfills in Mecklenburg County, North Carolina, 1980-86
A water-quality study was conducted during 1980-86 at four landfills in Mecklenburg County, North Carolina. Each landfill has a three-layered hydrogeologic system typical of the Piedmont, consisting of (1) the regolith; (2) a transition zone; and (3) unweathered, fractured crystalline bedrock. As much as 7.6 inches per year of rainfall enters the ground-water system and has the potential...

Acute toxicity of selected herbicides and surfactants to larvae of the midge Chironomus riparius Acute toxicity of selected herbicides and surfactants to larvae of the midge Chironomus riparius
The acute toxicities of eight commercial herbicides and two surfactants to early fourth instar larvae of the midgeChironomus riparius were determined under static conditions. The formulated herbicides tested were Eradicane® (EPTC), Fargo® (triallate), Lasso® (alachlor), ME4 Brominal® (bromoxynil), Ramrod® (propachlor), Rodeo® (glyphosate), Sencor®(metribuzin), and Sutan (+)® (butylate)...

Horizontal anisotropy of the principal ground-water flow zone in the Salinas alluvial fan, Puerto Rico Horizontal anisotropy of the principal ground-water flow zone in the Salinas alluvial fan, Puerto Rico
Well drawdown data from an anisotropic aquifer in the Salinas alluvial fan were collected and analyzed with a computer program called TENSOR2D. The program uses ordinary and weighted least-squares optimization procedures to solve the system of simultaneous equations needed to define the theoretical transmissivity ellipse. Prediction of drawdown data was made by coupling the anisotropy...

Microcontaminants and reproductive impairment of the Forster's tern on Green Bay, Lake Michigan,1983 Microcontaminants and reproductive impairment of the Forster's tern on Green Bay, Lake Michigan,1983
For the 1983 nesting season, Forster's tern (Sterna forsteri) reproductive success was significantly impaired on organochlorine contaminated Green Bay, Lake Michigan compared to a relatively uncontaminated inland location at Lake Poygan, Wisconsin. Compared with tern eggs from Lake Poygan, eggs from Green Bay had significantly higher median concentrations of 2,3,7,8-tetrachlorodibenzo-p...

Convergance experiments with a hydrodynamic model of Port Royal Sound, South Carolina Convergance experiments with a hydrodynamic model of Port Royal Sound, South Carolina
A two-demensional, depth-averaged, finite-difference, flow/transport model, SIM2D, is being used to simulate tidal circulation and transport in the Port Royal Sound, South Carolina, estuarine system. Models of a subregion of the Port Royal Sound system have been derived from an earlier-developed model of the entire system having a grid size of 600 ft. The submodels were implemented with...

Use of experimental ecosystems in regulatory decision making Use of experimental ecosystems in regulatory decision making
Tiered testing for the effects of chemicals on aquatic ecosystems has begun to include tests at the ecosystem level as a component in pesticide regristration. Because such tests are expensive, regulators and industry need to know what additional information they can gain from such tests relative to the costs of the simpler single-species toxicity bioassays. Requirements for ecosystem...
