Deprivation of Equations Describing Solute Transport in Ground Water (open access)

Deprivation of Equations Describing Solute Transport in Ground Water

Abstract: A general equation describing the three-dimensional transport and dispersion of a reacting solute in flowing ground water is derived from the principle of conservation of mass. The derivation presented in this report is more detailed but less rigorous than derivations published previously. The general solute-transport equation relates concentration changes to hydrodynamic dispersion, convective transport, fluid sources and sinks, and chemical reactions. Because both dispersion and convective transport depend on the velocity of ground-water flow, the solute-transport equation must be solved in conjunction with the ground-water flow equation.

Ground-Water Storage in the Johnson Valley Area, San Bernardino County, California (open access)

Ground-Water Storage in the Johnson Valley Area, San Bernardino County, California

Abstract: The Mojave Water Agency includes several desert basins where ground water in storage is many times as great as the average annual recharge. The Johnson Valley area was evaluated to find (1) the quantity of ground water in storage, (2) the chemical quality of the ground water, and (3) the potential for storage of recharge water in the unsaturated zone. Johnson Valley contains about 250,000 acre-feet of water in storage, of which about half can be considered recoverable. About 250,000 acre-feet of void space in the unsaturated alluvium is available for storage of imported water, but considerably less than this amount of recharged water could be recovered. The quality of the water in storage is satisfactory for public consumption, although water from some areas has high fluoride concentrations and should be mixed with water of low fluoride concentration.

Chemical, Physical, and Radiological Quality of Selected Public Water Supplies in Florida, November 1977-February 1978 (open access)

Chemical, Physical, and Radiological Quality of Selected Public Water Supplies in Florida, November 1977-February 1978

Abstract: Virtually all treated public water supplies sampled in Florida meet the National Inter-Primary and Proposed Secondary Drinking Water Regulations. These findings are based on a water-quality reconnaissance of 129 treated public supplies throughout the State during the period November 1977 through February 1978. While primary drinking water regulation exceedences were infrequent , lead, selenium, and gross alpha radioactivity in a very few water supplies were above established maximum contaminant levels. Additionally , the secondary drinking water regulation parameters--dissolved solids, chloride, sulfate, iron, color, and pH--were occasionally detected in excess of the proposed Federal regulations. The secondary regulations, however, pertain mainly to the aesthetic quality of drinking water and not directly to public health aspects.

Effects of Landfill Leaching on the Water Quality and Biology of a Nearby Stream, South Cairo, Greene County, New York (open access)

Effects of Landfill Leaching on the Water Quality and Biology of a Nearby Stream, South Cairo, Greene County, New York

From abstract: A 1-kilometer stream reach receiving leachate-enriched water from a small municipal landfill was studied from 1971-75 to document streamflow rates and chemical quality of the stream and ground water. The distribution of benthic invertebrates and microorganisms in the stream above the landfill was markedly different from that below it; the difference is attributed to the inflow of leachate.

Plan of Study for the Northern Midwest Regional Aquifer-System Analysis

From abstract: Sedimentary rocks of Cambrian and Ordovician age form a major aquifer system in most of Wisconsin and Iowa, northern Illinois, northwestern Indiana, southeastern Minnesota, and northern Missouri. Many metropolitan areas depend on the aquifer for all or part of their water supplies. Declines in potentiometric head have been large in the most heavily pumped areas, most notably Chicago, Milwaukee-Waukesha, Minneapolis-St. Paul, and Des Moines.

Analysis of Stream Quality in the Yampa River Basin, Colorado and Wyoming (open access)

Analysis of Stream Quality in the Yampa River Basin, Colorado and Wyoming

From introduction: This report relates to the first of the above objectives by describing stream quality in the Yampa River basin through 1976, with particular emphasis on conditions from August 1975 through September 1976. The content of this report is, at times, relatively technical. This is intentional. The report is aimed not at planners and decision makers but rather at those persons assigned the task of having to design, implement, and interpret a river basin assessment. The techniques and procedures used to determine ambient stream quality in the Yampa River basin have been presented in detail so that their applicability to other river basins can be determined. For the planner and decision maker, the results presented in this report are summarized in less technical terms in phase-l (Steele and others, 1979) and phase-ll summary reports.

Plan of Study for the Northern Atlantic Coastal Plain Regional Aquifer System Analysis (open access)

Plan of Study for the Northern Atlantic Coastal Plain Regional Aquifer System Analysis

Abstract: Sediments of Cretaceous to Holocene age compose the Northern Atlantic Coastal Plain aquifer system in an area of 50,000 square miles from North Carolina to New York. The aquifer system is the principal source of water supply for most of the area. About 1.4 billion gallons are withdrawn each day. Increasing pumpage has create~ problems such as declining water levels, saltwater intrusion, and land subsidence. The U.S. Geological Survey has begun a comprehensive study of the aquifer system that will define the geology, hydrology, and geochemistry of the system. The effects of future utilization of the aquifer system will be determined and alternative water withdrawal plans will be evaluated through computer simulation modeling. This report describes the objectives, organization, and work plans of the study.

Effects of Coal Fly-Ash Disposal on Water Quality in and Around the Indiana Dunes National Lakeshore, Indiana (open access)

Effects of Coal Fly-Ash Disposal on Water Quality in and Around the Indiana Dunes National Lakeshore, Indiana

Abstract: Dissolved constituents in seepage from fly-ash settling ponds bordering part of the Indiana Dunes National Lakeshore (the Lakeshore) have increased trace elements, and gross alpha and gross beta radioactivity in the ground water and surface water downgradient from the settling ponds. Data suggest that concentrations of some dissolved trace elements may be greater beneath interdunal pond 2 than in the pond. The soil system downgradient from the settling ponds seems to have affected the concentrations of dissolved ions in the settling-ponds than in the ponds. Where organic material was present downgradient from the settling ponds, concentrations of arsenic, fluoride, molybdenum, potassium, sulfate, and strontium were greater in the ground water than in the ponds. In contrast, the concentrations of cadmium, copper, nickel, aluminum, cobalt, lead, and zinc were less.
