Manufacturing Facilities Release Pharmaceuticals to the Environment
In a 2004-2009 study, U.S. Geological Survey (USGS) scientists found that pharmaceutical manufacturing facilities can be a significant source of pharmaceuticals to the environment. Effluents from two wastewater treatment plants (WWTPs) that receive discharge from pharmaceutical manufacturing facilities (PMFs) had 10 to 1000 times higher concentrations of pharmaceuticals than effluents from 24...
Tackling Fish Endocrine Disruption
Intersex, the presence of both male and female characteristics within the same fish, is being observed in fish in more streams across the Nation. Intersex is one manifestation of endocrine disruption in fish. Endocrine disruption can result in adverse effects on the development of the brain and nervous system, the growth and function of the reproductive system, and the response to stressors in the...
Measuring Antidepressants, Fungicides, and Insecticides in the Environment
U.S. Geological Survey (USGS) scientists are developing new laboratory analytical methods to measure contaminants in samples of environmental water, sediment, and soil. The work is part of a continuing effort to provide information on new and understudied contaminants to water-resource managers, environmental regulators, and the public. The new methods are used by USGS scientists and others to...
Emerging Contaminants Targeted in a Reconnaissance of Ground Water and Untreated Drinking-Water Sources
Two national-scale reconnaissance studies recently conducted by the U.S. Geological Survey (USGS) were the first to collect baseline information on the environmental occurrence of pharmaceuticals, personal-care products, detergents, flame retardants, naturally occurring sterols, and other organic contaminants in ground water and untreated sources of drinking water in the United States. These...
Household Chemicals and Drugs Found in Biosolids from Wastewater Treatment Plants
Biosolids, the treated sludge generated by the treatment of sewage at wastewater treatment plants, is something that most people don't think about as they flush everyday chemicals and drugs down the drain. However, U.S. Geological Survey (USGS) scientists found that biosolids contain relatively high concentrations (hundreds of milligrams per kilogram) of the active ingredients commonly found in a...
Pharmaceuticals Found in Soil Irrigated with Reclaimed Water
Many areas of the Nation are faced with water shortages due to significant demand for water. As a result, supplies are being augmented with treated wastewater for uses such as irrigation. In a study recently published in the journal "Environmental Toxicology and Chemistry," a team of U.S. Geological Survey (USGS) scientists reported that pharmaceuticals in wastewater used for irrigation persist in...

Preliminary estimates of residence times and apparent ages of ground water in the Chesapeake Bay watershed, and water-quality data from a survey of springs Preliminary estimates of residence times and apparent ages of ground water in the Chesapeake Bay watershed, and water-quality data from a survey of springs
Knowledge of the residence times of the ground-water systems in Chesapeake Bay watershed helps resource managers anticipate potential delays between implementation of land-management practices and any improve-ments in river and estuary water quality. This report presents preliminary estimates of ground-water residence times and apparent ages of water in the shallow aquifers of the...

Selected characteristics of stormflow and base flow affected by land use and cover in the Chickahominy River basin, Virginia, 1989-91 Selected characteristics of stormflow and base flow affected by land use and cover in the Chickahominy River basin, Virginia, 1989-91
The Chickahominy River is the principal source of raw-water supply managed by the Department of Public Utilities, City of Newport News. Selected characteristics of stormflow and base flow, and major land use and cover factors that affect the distribution, movement, and quality of water of the nontidal Chickahominy River were monitored at three continuous-record stations and two partial...

Potentiometric surface of the middle Potomac Aquifer in Virginia, 1993 Potentiometric surface of the middle Potomac Aquifer in Virginia, 1993
Ground-water level measurements from 50 wells in the middle Potomac aquifer in the Coastal Plain Physiographic Province of Virginia in 1993 were used to prepare a map of the potentiometric surface of the aquifer. The map shows the potentiometric surface of the middle Potomac aquifer sharply declining eastward from nearly 100 feet above sear level near the western boundary of the aquifer...
