Energy Production Materials Exposure

Human activities can enrich toxic trace elements like uranium and arsenic in the environment, but these elements also are from natural sources and occur at background levels. Scientists utilized a technique that identifies the background and the elemental fingerprint of human-caused enrichment and tested the new technique on data collected near uranium mines in Arizona.

USGS scientists use innovative isotopic identification methods to determine mercury sources in air, water, sediments, and wildlife.

The public is concerned that uranium in natural geologic formations, mine tailings, dusts, water, and other geologic materials can pose a health hazard to humans and wildlife. Our specialized teams of hydrologists, chemists, and geologists working together at a field site in the Grand Canyon region of the United States have shown: Elevated uranium concentrations (above the drinking water standard)...

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.

Livestock manure spills have been shown to result from events such as equipment failures, over-application of manure to agricultural fields, runoff from open feedlots, storage overflow, accidents with manure transporting equipment, and severe weather. Our specialized teams of hydrologists, chemists, biologists and geologists, in collaboration with Johns Hopkins Bloomberg School of Public Health...

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...

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...

Scientists found that naturally occurring arsenic in aquifer sediments was mobilized into groundwater and attenuated through reattachment to sediments within an underground petroleum plume. Understanding these patterns identifies anthropogenic factors that affect arsenic presence and magnitude in groundwater.

The U.S. Geological Survey (USGS) 2016 Early Career Excellence in Leadership Award was given to Dr. Denise M. Akob and Dr. Karl B. Haase. Drs. Akob and Haase have demonstrated outstanding leadership through their scientific accomplishments and service to the USGS.

Shifts in the overall microbial community structure were present in stream sediments that contained chemicals associated with unconventional oil and gas wastewaters. This work is part of a long-term study designed to understand persistence of chemicals from oil and gas wastewaters in sediments and water and how those factors might be related to exposures and adverse health effects, if any, on...

Research at a 1979 crude oil spill from a ruptured pipeline has exposed and helped to overcome many challenges facing an effective, cost-efficient cleanup of crude oil, U.S. Geological Survey (USGS) scientists have found. The environmental release of crude oil occurred near Bemidji, Minnesota.

Waters produced as a byproduct of oil and gas development were found to yield high concentrations of disinfection byproducts (DBPs) when treated. The U.S. Geological Survey (USGS) sampled stream waters upstream and downstream of the outfall of Publicly Owned Wastewater Treatment Works (POTWs), POTWs that receive and treat waters produced by conventional and unconventional oil and gas development...
