Water-quality and hydrogeologic data used to evaluate the effects of farming systems on ground-water quality at the Management Systems Evaluation Area near Princeton, Minnesota, 1991-95
The Minnesota Management Systems Evaluation Area (MSEA) project was part of a multi-scale, inter-agency initiative to evaluate the effects of agricultural management systems on water quality in the midwest corn belt. The research area was located in the Anoka Sand Plain about 5 kilometers southwest of Princeton, Minnesota. The ground-water-quality monitoring network within and immediately surround

Effects of produced waters at oilfield production sites on the Osage Indian Reservation, northeastern Oklahoma
The authors conducted limited site surveys in the Wildhorse and Burbank oilfields on the Osage Indian Reservation, northeastern Oklahoma. The purpose was to document salt scarring, erosion, and soil and water salinization, to survey for radioactivity in oilfield equipment, and to determine if trace elements and naturally occurring radioactive materials (NORM) were present in soils affected by oilf

Use of tracer injections and synoptic sampling to measure metal loading from acid mine drainage
Thousands of abandoned and inactive mines are located in environmentally sensitive mountain watersheds. Cost-effective remediation of the effects of metals from mining in these watersheds requires knowledge of the most significant sources of metals. The significance of a given source depends on the toxicity of a particular metal, how much of the metal enters the stream, and whether or not the meta

The travel times of solutes at the Cape Cod Tracer Experiment: Data analysis, modeling, and structural parameters inference
A method for analyzing and interpreting travel times of solutes in heterogeneous aquifers is presented based on the peak concentration arrival times as measured at various samplers in the aquifer. The method allows separation of the effects of pore-scale dispersion from the effects of the large-scale aquifer heterogeneity. An analysis of data from the Cape Cod field experiment is presented, and we

USGS research on saline waters co-produced with energy resources
The United States energy industry faces the challenge of satisfying our expanding thirst for energy while protecting the environment. This challenge is magnified by the increasing volumes of saline water produced with oil and gas in the Nation's aging petroleum fields. Ultimately, energy-producing companies are responsible for disposing of these waters. USGS research provides basic information, fo

Numerical simulation of ground-water flow through glacial deposits and crystalline bedrock in the Mirror Lake area, Grafton County, New Hampshire
This report documents the development of a computer model to simulate steady-state (long-term average) flow of ground water in the vicinity of Mirror Lake, which lies at the eastern end of the Hubbard Brook valley in central New Hampshire. The 10-km2 study area includes Mirror Lake, the three streams that flow into Mirror Lake, Leeman's Brook, Paradise Brook, and parts of Hubbard Brook and the Pem

A rapid and simple method for estimating sulfate reduction activity and quantifying inorganic sulfides
A simplified passive extraction procedure for quantifying reduced inorganic sulfur compounds from sediments and water is presented. This method may also be used for the estimation of sulfate reduction rates. Efficient extraction of FeS, FeS2, and S2- was obtained with this procedure; however, the efficiency for S0 depended on the form that was tested. Passive extraction can be used with samples co

Estimating ground-water recharge from streamflow hydrographs for a small mountain watershed in a temperate humid climate, New Hampshire, USA
Hydrographs of stream discharge were analyzed to determine ground-water recharge for two small basins draining into Mirror Lake, New Hampshire. Two methods of hydrograph analysis developed for determining ground-water recharge were evaluated, the instantaneous recharge method and the constant recharge method. For the instantaneous recharge method, recharge is assumed to be instantaneous and unifor
