Technical protocol for evaluating natural attenuation of chlorinated solvents in ground water
This Protocol is designed to evaluate the fate in ground water of chlorinated aliphatic hydrocarbons and/or fuel hydrocarbons. Documentation of natural attenuation requires detailed site characterization. The data collected under this protocol can be used to compare the relative effectiveness of other remedial options. and natural attenuation. This protocol should be used to evaluate whether monit

Hydrogeology and water quality in the Cedar Rapids area, Iowa, 1992-96
The U.S. Geological Survey (USGS) and the city of Cedar Rapids conducted a cooperative study from 1992 to 1996 to assess the hydrogeology and water quality in the Cedar River, Cedar River alluvial aquifer, Devonian aquifer, and Silurian aquifer in a 231-square-mile area of Benton and Linn Counties near Cedar Rapids, Iowa. The city of Cedar Rapids withdrew an average of 34 million gallons per day b

Streamflow characteristics for the Black Hills of South Dakota, through water year 1993
This report summarizes streamflow records and describes streamflow characteristics for streams draining the Black Hills of western South Dakota. Monthly and annual streamflow records are tabulated for all available years of record, through water year 1993, for 129 continuous-record gaging stations, including 111 stations for which records of daily flow are available and 18 stations for which only

Geohydrology of the Central Oahu, Hawaii, ground-water flow system and numerical simulation of the effects of additional pumping
A two-dimensional, finite-difference, ground-water flow model was developed for the central Oahu flow system, which is the largest and most productive ground-water flow system on the island. The model is based on the computer code SHARP which simulates both freshwater and saltwater flow. The ground-water model was developed using average pumping and recharge conditions during the 1950's, which was

Wet atmospheric deposition of pesticides in Minnesota, 1989-94
All of the rain samples during the growing season had detectable quantities of at least one pesticide, but most of the pesticides were only infrequently observed. The most frequently detected compounds were the herbicides alachlor, atrazine, cyanazine, and metolachlor, and in 1994, its first year of registration, acetochlor. Peak concentrations of most herbicides in rainfall occurred shortly after

Ground water and streamflow in the Nett Lake Indian Reservation, northern Minnesota, 1995-97
The Nett Lake Indian Reservation, about 164 square miles in area, is in northern Minnesota. About 300 people live in Nett Lake Community, about 100 people live in Palmquist Community, and a few people live in other parts of the Reservation. Water resources in the Reservation include: (1) ground water in sand and gravel aquifers and bedrock aquifers; (2) Nett Lake; (3) streams in the Nett Lake Rive

Ground-water conditions in Georgia, 1997
Ground-water conditions in Georgia during 1997 and for the period of record were evaluated using data from ground-water-level and ground-water-quality monitoring networks. Data for 1997 included in this report are from continuous water-level records from 71 wells and chloride analyses from 14 wells.
In 1997, annual mean ground-water levels in Georgia ranged from 6.2 feet (ft) lower to 5.6 ft hi

Transport, behavior, and fate of volatile organic compounds in streams
Volatile organic compounds (VOCs) are compounds with chemical and physical properties that allow the compounds to move freely between the water and air phases of the environment. VOCs are widespread in the environment because of this mobility. Many VOCs have properties making them suspected or known hazards to the health of humans and aquatic organisms. Consequently, understanding the processes af
