Effects of Sanitary Sewers on Ground-Water Levels and Streams in Nassau and Suffolk Counties, New York, Part 1: Geohydrology, Modeling Strategy, and Regional Evaluation (open access)

Effects of Sanitary Sewers on Ground-Water Levels and Streams in Nassau and Suffolk Counties, New York, Part 1: Geohydrology, Modeling Strategy, and Regional Evaluation

From purpose and scope: This report is the first in a three-part series describing the U.S. Geological Survey's efforts in the detailed hydrologic investigation of southern Nassau and southwest Suffolk Counties, which includes a ground-water modeling study to predict the effects of an extensive sewer network scheduled to be completed in 1985. As the introduction to the series, this report has four objectives: (1) to present a detailed description of the hydrologic system in the area, including newly acquired hydrogeologic information; (2) to define the hydrogeologic factors that will be affected by the sewer network; (3) to explain the modeling strategy and describe the techniques used to develop the ground-water models of the two adjacent areas studied; and (4) to present a preliminary evaluation of the effects of sewers as predicted by a regional ground-water flow model.

An Analysis of Salinity in Streams of the Green River Basin (open access)

An Analysis of Salinity in Streams of the Green River Basin

Abstract: Dissolved-solids concentrations and loads can be estimated from streamflow records using a regression model derived from chemical analyses of monthly samples. The model takes seasonal effects into account by the inclusion of simple-harmonic time functions. Monthly mean dissolved-solids loads simulated for a 6-year period at U.S. Geological Survey water-quality stations in the Green River Basin of Wyoming agree closely with corresponding loads estimated from daily specific-conductance records. In a demonstration of uses of the model, an average gain of 114,000 tons of dissolved solids per year was estimated for 6-year period in a 70-mile reach of the Green River from Fontemelle Reservoir to the town of Green River, including the lower 30-mile reach of the Big Sandy River.

Waterlogging in an Alluvial Aquifer near Lake Minnequa, Pueblo, Colorado (open access)

Waterlogging in an Alluvial Aquifer near Lake Minnequa, Pueblo, Colorado

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.

Investigation of Waikele Well No. 2401-01, Oahu, Hawaii: Pumping Test, Well Logs and Water Quality (open access)

Investigation of Waikele Well No. 2401-01, Oahu, Hawaii: Pumping Test, Well Logs and Water Quality

Introduction: A dependable water supply is required for Naval Magazine Lualualei, Waikele Branch. The water supply for Naval Magazine Lualualei, Waikele Branch, Oahu, Hawaii has been dependent on Oahu Sugar Co.'s water for many years. Because the supply of water from Oahu Sugar Co. is not always dependable, in March 1982, the Pacific Division of the Naval Facilities Engineering Command entered into a cooperative agreement with the U.S. Geological Survey to determine the productivity and water quality of an abandonment Navy well. The well, No. 2401-01, is located in Waikele Gulch near the confluence of Waikele and Kipapa Streams (fig. 1.0-1)

WATEQF: A FORTRAN IV Version of WATEQ, a Computer Program for Calculating Chemical Equilibrium of Natural Waters

Abstract: WATEQF is a FORTRAN IV computer program that models the thermodynamic speciation of inorganic ions and complex species in solution for a given water analysis. The original version (WATEQ) was written in 1973 by A. H. Truesdell and B. F. Jones in Programming Language/one (PL/1). With but a few exceptions, the thermochemical data, speciation, activity coefficients, and general calculation procedure of WATEQF is identical to the PL/1 version. This report notes the differences between WATEQF and WATEQ, demonstrates how to set up the input data to execute WATEQF, provides a test case for comparison, and makes available a listing of WATEQF.
