Distribution and Movement of Zinc and Other Heavy Metals in South San Francisco Bay, California

Description: From introduction: The primary objective of this study was to determine the net transport of zinc into the study area from urbanized perimeter, out of the study area across the northern boundary of the study area, and across the sediment-water interface within the study area, all within a limited time period. A secondary objective was to assemble as much data on other trace metals--their concentrations and chemical states in water, suspended solids, sediments and interstitial fluids--as possible within the time and funding constraints of the study in order to describe the existing trace metal conditions in the south bay. Thus the bulk of effort was directed toward evaluating the distribution and movements of zinc, but the data collected on the distribution and movements of zinc, but the data collected on the distribution of other metals is important and is reported here.

Evaluating Pollution Potential of Land-Based Waste Disposal Santa Clara County, California -- An Application of Earth-Science Data for Planning

Description: From introduction: As a result of recently initiated programs such as the San Francisco Bay Region Environment and Resources Planning Study, planners in the San Francisco Bay region are becoming increasingly aware of the types and possible uses earth-science data. These data encompasses a wide spectrum of disciplines including hydrology, topography, geology, geomorphology, and seismology. If properly integrated with the planner's competence in demography, sociology, economics, and other fields, earth-science data can be invaluable for evaluating and controlling many critical environment problems in urban areas.

Geohydrology of the Anza-Terwilliger Area, Riverside County, California

Description: The Anza-Terwilliger area consists of about 96 square miles (24-9 square kilometers) in the upper parts of the Santa Margarita River and Coyote Creek drainage basins in Riverside County, Calif., about 90 miles (145 kilometers) southeast of Los Angeles. This report deals with geology, steady state and transient state of ground water, net depletion of ground water, surface-water flow, precipitation, chemistry of water, land and water use, and gravity data for the Anza-Terwilliger area. The data indicate that the rate of ground-water depletion ha's accelerated since 1950. Pumping depressions adjacent to the Cahuilla Indian Reservation have increased the hydraulic gradient and are.causing water beneath the reservation to flow toward these depressions. Total depletion of ground water since 1950 is about 14,000 acre-feet (17.3 cubic hectometers). Chemical analyses indicate that the ground water in local areas contains concentrations of nitrate above that recommended by the Environmental Protection Agency for human consumption.

Feasibility of Digital Water-Quality Modeling Illustrated by Application at Barstow, California

Description: Abstract: A digital water-quality model of the shallow alluvial aquifer near Barstow was evaluated to determine the applicability of the model computer program to varied hydrolic problems. The evaluation was made on the basis of the data requirements of the model, the characteristics and limitations of the model computer program, the relevance of the model results, and the computer costs associated with the model. Two-well tracer-dilution tests may not be a workable means of determining the aquifer dispersivity and porosity for use in a water-quality model with a large grid interval is under consideration because of the relative insensitivity of such a model to dispersivity. The model results were relevant to the real-life head and water-quality conditions in the aquifer near Barstow and provided an excellent means of evaluating the cause and effect relations associated with ground-water pollution.

Ground Water in the Northeast Part of Twentynine Palms Marine Corps Base, Bagdad Area, California

Description: Purpose and scope: The U.S. Marine Corps conducts training maneuvers in the study area. Lack of a local source of water has severely limited the utilization of the area. In the past, limited quantities of water have been transported to the area by truck or helicopter. The purpose of this study was to determine the feasibility of obtaining a supply of ground water in the area for use when field maneuvers are being conducted. The major effort for this study was concentrated on the part within the Marine Corps base boundary. The study involved the assessment of ground-water quality, ground water in storage, and aquifer characteristics.

Distribution of Nitrate in Ground Water Redlands, California

Description: Report and geographical survey. This report examines the distribution of nitrates in the Redland area's ground water and concludes that this distribution depends primarily upon depth below the water table and areal location. Includes several maps and figures.

Map Showing Outcrops of Basaltic Rocks of Early Quaternary and Tertiary Age, Basin and Range Province, Southern California

Description: From introduction: This map report is one of a series of geologic and hydrologic maps covering all or parts of States within the Basin and Range province of the western United States. The map reports contain detailed information on subjects that characterize the geohydrology of the province, including the ground-water hydrology, ground-water quality, surface distribution of selected rock types, tectonic conditions, areal geophysics, Pleistocene lakes and marches, and mineral and energy resources This is part of the U.S. Geological Survey's program for geologic and hydrologic evaluation of the province to identify prospective regions for further study relative to isolation of high-level nuclear waste.

A Method for Estimating Ground-Water Return Flow to the Lower Colorado River in the Yuma Area, Arizona and California

Description: Purpose and scope: The purpose of this study was to develop a method for estimating the amount of subsurface return flow to the Colorado River in the Yuma area. This report presents a method that permits an approximate accounting of ground-water return flow from each side of the Colorado River in Yuma reach. The method presented in this report was developed specifically for application in the Yuma area. The validity of the assumptions inherent in the method was evaluated on the basis of the local hydrologic system. The applicability of the method to other hydrologic systems is not addressed in this report.

Artificial Recharge in the Northern Part of Chino Ground-Water Basin, Upper Santa Ana Valley, California

Description: Purpose and Scope: The purpose of this study was to evaluate the geohydrologic characteristics that influence sustained artificial recharge and to determine long-term infiltration rates in the northern part of Chino ground-water basin. Results of this study will help management to design and implement a recharge-recapture system in Chino Basin. Nine test holes were drilled, long-term infiltration tests were made, and drillers' logs and water-level data were evaluated to determine the probable effects of recharging the ground-water basin. The study was concentrated in the northern part of Chino Basin, where recharge is proposed.
