This report was formed after the study of the Nevada Test Site to examine parts of the thick miogeosynclinical section of the Paleozoic rocks and post-Paleozoic structural features for the sole purpose of determining the walking stops for future field trips to the test site.

This report summarizes the stratigraphy, lithology, and physical properties studied in the UE12p#1 exploratory diamond drill hole at the Nevada Test Site.

This report evaluates a cavity-riddled zone of an aquifer near Riviera Beach, Florida. It includes maps, graphs, and other figures.

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.

This report presents the water-quality data of Raystown Lake, Pennsylvania, discussing its physical, biological, and chemical properties. This report also includes several tables and figures.

Abstract: The Lake Minnequa area, located immediately south of the Arkansas River, is mantled with as much as 46 feet (14 meters) of alluvium covering bedrock of Pierre Shale and Niobrara Formation. Surface water enters the area by the Minnequa Canal and the St. Charles Flood Ditch. The water is stored in Lake Minnequa and other reservoirs. Seepage from St. Charles Reservoirs No. 2 and No. 3 is the major source of water to the alluvial aquifer. The depth of the water table ranges from 0 to 40 feet (0 to 12.2 meters). A 0.5-square-mile (1.3-square-kilometers) area immediately south of Lake Minnequa has a water table less than 6 feet (1.8 meters) below land surface. Lake Minnequa is the principal cause of the shallow water table and resulting waterlogged soil. The bedrock hill east of Lake Minnequa and ground-water flow also contribute to the problem. To eliminate the waterlogging problem, the water table would have to be at least 6 feet (1.8 meters) below land surface. Possible alternatives for eliminating the problem include lowering the water, level in Lake Minnequa, placing a network of dewaterinq wells, or constructing a drainage system in the waterlogged area.

From introduction: This report contains geohydrologic and water-quality data, hydrologic testing methods, and preliminary interpretations related to the site area and it supplements a report in which the regional hydrogeologic regime was described (Mercer and Orr, 1977).

From abstract: Channel-routing models were used to route hypothetical releases from reservoirs in the upper Tioga River basin, Pennsylvania. These releases were routed northward down the Tioga River to Lindley, Erwins, and Corning, New York; combined with flows routed down the Cohocton River from Campbell to Corning, New York; and then routed southeastward down the Chemung River from Corning to Chemung, New York. The models used to route the flows of Cohocton and Chemung Rivers accounted for bank-storage discharge and streamflow depletion by well pumpage. In general, 17 years of concurrent streamflow data were available for model calibration and verification.

From introduction: The purpose of the study was to describe the differences between ponds that developed within and abandoned mine site and in control ponds not affected by mining.

From introduction: The purpose of this report is to describe the hydrologic system in the Lake Wingra basin, with particular emphasis on the hydrolic budget of the lake itself.

Abstract: Details of additions and modifications to a computer code described in an earlier report entitled "A model for calculating effects of liquid waste disposal in deep saline aquifers,: USGS WRI 76-61, NTIS-PB256 903/AS are documented. These additions and modifications include free water surface, vertical recharge, equilibrium controlled linear absorption and a first order irreversible rate reaction. These, plus additional modifications, make this model more adaptable to general hydrologic problems and those involving waste disposal with simple chemical reactions.

Abstract: The discharge-weighted average concentrations of dissolved solids, chloride, and sulfate for many of the principal streams in Texas are less than 500 mg/1 (milligrams per liter), 250 mg/1, and·250 mg/1, respectively. At 65 of 131 sites on streams that were sampled at least 10 times, the biochemical oxygen demand of at· least half the samples exceeded 3,0 mg/1. At 20 of the sites, the dissolved-oxygen content of at least !half the samples was less than 5.0_ mg/1. The higher concentrations of minor elements usually were detected in waters from urban areas, indicating a relation to man's activities. Small amounts of some pesticides are widely distributed in low concentrations. The higher concentrations usually were detected in waters from urban areas. Small amounts of some of the pesticides studied are widely distributed in surface waters in Texas. Some of the more widely distributed pesticides were 2,4,5-T at 96 sites, diazinon at 80 sites, 2,4-D at 78 sites, dieldrin at 77 sites, Silvex at 47 sites, DDT at 67 sites, lindane at 59 sites, DDD at 51 sites, DDE at SO sites, and chlordane at 38 sites.
