A Field Method to Quantify Chlorinated Solvent Diffusion, Sorption, Abiotic and Biotic Degradation in Low-Permeability Zones

Strategic Environmental Research and Development Program project ER-2533 In chlorinated-solvent-contaminated fractured-sedimentary-rock aquifers, low-permeability (low-K) strata typically act as long-term or secondary sources of contamination to mobile groundwater in the high-permeability fractures. The fate of dissolved trichloroethene (TCE) in the low-K matrix is controlled by abiotic...

Nationwide Occurrence

A National-scale approach is used to examine and analyze per- and polyfluoroalkyl substances (PFAS) prevalence and magnitude in watersheds and aquifers. As an initial step to fill known science gaps in the understanding of human and wildlife exposure, the team will provide a snapshot of PFAS in drinking water paired with bioaccumulation in fish and wildlife near known or suspected sources of...

Contaminant Fate and Transport Studies in Fractured Sedimentary Rock Aquifers at the former Naval Air Warfare Center (NAWC), West Trenton, N.J.

Contaminants associated with industrial, airport, and other activities are present in groundwater in fractured-rock aquifers, posing long-term hazards to drinking-water supplies and ecosystems. The heterogeneous character of fractured rock challenges our understanding, monitoring, and remediation of such sites.

Refined Model Provides a Screening Tool to Understand Exposure to Contaminants from Incidental Wastewater Reuse

Refinement of the existing national-scale “de facto reuse incidence in our nation’s consumable supply” (DRINCS) model, complemented by field measurements, provides a screening tool to understand human and wildlife exposure to toxicants and pathogens associated with the incidental reuse of treated wastewater in the Shenandoah River watershed. The model results can be accessed in a companion web...

Ongoing Research to Characterize the Complexity of Chemical Mixtures in Water Resources—Urban Stormwater

A multiagency reconnaissance study of chemicals in urban stormwater, sampled from pipes or ditches during 50 runoff events at 21 sites in 17 states across the United States, demonstrated that stormwater runoff contains complex mixtures of chemicals including polycyclic aromatic hydrocarbons, pesticides, and pharmaceuticals that are indicative of multiple sources in the watershed.

Can There be Unintended Benefits when Wastewater Treatment Infrastructure is Upgraded?

Science from the U.S. Geological Survey (USGS) and other entities has shown that a mixture of natural and synthetic estrogens and other similar chemicals are discharged from wastewater treatment plants (WWTPs) to streams and rivers.

Are Spills Associated with Deep Well Injection of Wastewater from Oil and Gas Operations a Health Hazard?

Our specialized teams of hydrologists, chemists, biologists, and geologists worked together in the New River Gorge National River watershed to answer this question. Wastewater generated in association with oil and gas operations at this site is managed by injection in deep wells designed to safely dispose and contain contaminants in deep geologic formations. Contaminants associated with oil and...

Selected Pharmaceuticals Not Likely to Persist in Wild Fish: Results of Uptake and Elimination Testing

Laboratory study shows that both uptake and elimination of selected pharmaceuticals within bluegill tissues is rapid indicating that persistence in bluegills in the environment is likely to be low except in those fish that reside downstream from a consistent, substantial, contaminant source.

Energy Integrated Science Team

The Energy Lifecycle Integrated Science Team focuses on the potential for contaminant exposures in the environment that might originate from energy resource activities including, extraction, production, transportation, storage, extraction, waste management and restoration. Perceived health risks to humans and other organisms will be distinguished from actual risks, if any. If actual risks are...

Commonly Used Chemicals Transported to Agricultural Field through Municipal Biosolids Application

Commonly used chemicals (including fragrances, detergents, fire retardants, plasticizers, and antibacterials) transferred to wastewater treatment plants were detected in municipal wastewater biosolids applied to agricultural field plots and subsequently detected in the runoff transported from the plots during precipitation events.
