Availability and Chemical Quality of Water From Surficial Aquifers in Southwest Minnesota
From introduction: The objectives of the study were to (1) determine the areal extent, thickness, and water-yielding capability of aquifers in the surficial deposits, (2) estimate the amount of water in storage in the aquifers, (3) determine the chemical quality of water in the aquifers and, (4) establish observation wells to monitor the effects of ground-water development on water levels and storage in the aquifers.

Ground Water in the Lajas Valley, Puerto Rico
Abstract: Lajas Valley is plagued with problems of salinity and waterlogging the soils. Use of brackish (500 milligrams per liter) irrigation compounded ground water for the problem until an irrigation-drainage system was constructed in 1955. Lajas is an alluvium-filled limestone highlands. The alluvium, mostly clay and as much 300 feet (90 meters) thick, contains brackish ground water except in the recharge areas located along the foothills...Results from a digital model show that a network of discharge wells could alleviate waterlogging of the soils in the artesian area.

Geohydrology of the Meadowbrook Artificial-Recharge Site at East Meadow, Nassau County, New York
Purpose and scope: The Meadowbrook artificial-recharge project, a cooperative effort between the U.S. Geological Survey and the Nassau County Department of Public Works (NCDPW) since 1975, is intended to demonstrate the feasibility of using reclaimed wastewater to replenish and improve the quality of Long Island's ground water. This report presents the results of geologic, hydrologic, and hydrochemical studies that were done at the Meadowbrook artificial-recharge site to define conditions prevailing before the start of recharge operations.

Effects of Ground-Water Development on the Proposed Palmetto Bend Dam and Reservoir in Southeast Texas
Abstract: Ground water continues to discharge into the Navidad and Lavaca Rivers by seepage out-flow even though large amounts of ground water are pumped for irrigation. Although a reduction in streamflow probably has occurred, a complete loss of the low flow of the streams by infiltration to a lowered water table seems remote. The large ground-water withdrawals will continue to cause land-surface subsidence, which will range from 0.012 foot to more than 0.026 foot per year. A minimum of about 0.013 to 0.015 foot of annual subsidence at the upper ends of the proposed reservoir and a maximum of about 0.019 foot near the dam site can be expected. Structural failures of manmade features have not occurred from the subsidence, but regional changes in the land slope have occurred and will continue . Numerous fault traces have been mapped in the area, but most of the faults are inactive. If movement along the fault planes should occur, the vertical displacement probably will not exceed the total subsidence.

Stream Reconnaissance for Nutrients and Other Water-Quality Parameters, Greater Pittsburgh Region, Pennsylvania
Abstract: Eighty-five stream sites in and near the six-county Greater Pittsburgh Region were sampled in mid-June 1971 and again in mid-October 1972. Concentrations of inorganic nitrogen, organic carbon, or phosphorus were high enough to indicate potential problems at about a quarter of the sampling sites. Temperature, dissolved oxygen, and pH values indicated a generally favorable capacity for recovery from degradation, although a number of streams east of the Allegheny and Monongahela Rivers are marginal or lacking. Regionally, sulfate is the dominant ion and was observed in concentrations of 40 milligrams per liter or more at 90 percent of the sites. Bicarbonate exceeded 100 milligrams per liter at 22 sites. A moderate to high degree of mineralization is indicated by conductance readings of more than 500 micromhos per centimeter at half of the sampling sites.

Water Resources of Manatee County, Florida
From introduction: The purpose of this report is (1) to describe the geology, hydrology, and quality of water of Manatee County and (2) to evaluate the availability of surface and ground water for development. The report provides Manatee County, the Southwest Florida Water Management District, and the Florida Department of Natural Resources with a data base and an evaluation of the water resources of the area so that water-quality and water-resource problems and water-management and regulatory needs can be adequately defined and documented.

Artificial-Recharge Experiments and Operations on the Southern High Plains of Texas and New Mexico
Abstract: Experiments using highly turbid water from playa lakes for injection into the Ogallala Formation have resulted in greatly decreased yield of the recharge wells. Recharge of ground or surface water of good quality has indicated, however, that injection through wells in an effective method of recharging the aquifer. Water that is slightly turbid can be successfully injected for a period of time, but generally results in constantly declining yields and capacity for recharge. Redevelopment through pumping and surging significantly prolongs the life of recharge wells under some conditions. Surface spreading is little practiced on the High Plains, but locally may be a feasible means of artificial recharge.

Ground Water in Carbonate Rocks and Regolith in the Fairview Area, Tennessee
From abstract: Fourteen test wells drilled in the Fairview area, Tennessee, produce from 3 to 100 gallons per minute and have an average yield of 32 gallons per minute; yields were measured while blowing water from the wells with compressed air. In comparison, the average yield of 134 supply wells reported by drillers is 13 gallons per minute. Specific capacities for three of the test wells ranged from 0.3 to 0.6 gallons per minute per foot of drawdown after 8 hours of pumping at 20 to 47 gallons per minute. Two test wells had specific capacities of 1.1 and 0.4 gallons per minute per foot of drawdown after 72 hours of pumping at 55 and 43 gallons per minute.

Hydrology of Coal-Resource Areas in the Southern Wasatch Plateau, Central Utah
From purpose and scope: The hydrology of coal-resource areas in the southern Wasatch Plateau in central Utah (fig. 1) was studied by the U.S. Geological Survey in cooperation with the U.S. Bureau of Land Management. The study area contains large coal reserves, and much of the area was unleased for mining in 1980. In general, study objectives were to define the surface- and ground-water hydrology and to predict, where possible, the effects of coal mining on the hydrologic system. Watersheds and aquifers that were the sole source of supply for public use were to be identified. The objectives were designed to provide the hydrologic information needed by the U.S. Bureau of Land Management to make sound decisions concerning the leasing of Federal lands for coal mining.
