Environmental Health Program

The Environmental Health Program (Contaminant Biology and Toxic Substances Hydrology) supports integrated natural science expertise and capabilities across the USGS related to environmental contaminants and pathogens. This One Health approach recognizes the interdependence of human and animal health and the health of ecosystems that they share.

Distribution of ancient carbon in groundwater and soil gas from degradation of petroleum near the Red Hill Bulk Fuel Storage Facility, O‘ahu, Hawai‘i

The groundwater below the Red Hill Bulk Fuel Storage Facility (the facility) in Oʻahu, Hawaiʻi, contains fuel compounds from past spills. This study used carbon-14 analyses to distinguish fuel-derived carbon from background carbon, along with other biodegradation indicators, to address two goals: (1) determine the extent and migration direction of groundwater affected by residual fuel...

Interdisciplinary science approach for harmful algal blooms (HABs) and algal toxins—A strategic science vision for the U.S. Geological Survey

Executive SummaryAlgal blooms in water, soils, dusts, and the environment have captured national attention because of concerns associated with exposure to algal toxins for humans and animals. Algal blooms naturally occur in all surface-water types and are important primary producers for aquatic ecosystems. However, excessive algae growth can be associated with many harmful effects...

Anaerobic biodegradation of perfluorooctane sulfonate (PFOS) and microbial community composition in soil amended with a dechlorinating culture and chlorinated solvents

Perfluorooctane sulfonate (PFOS), one of the most frequently detected per- and polyfluoroalkyl substances (PFAS) occurring in soil, surface water, and groundwater near sites contaminated with aqueous film-forming foam (AFFF), has proven to be recalcitrant to many destructive remedies, including chemical oxidation. We investigated the potential to utilize microbially mediated reduction...

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...

Immunomodulation Science Team

The Immunomodulation Integrated Science Team focuses on contaminant and pathogen exposures in the environment that might influence the immune systems of wildlife and the connection to their shared environment with humans. In collaboration with public-health officials, the Team also addresses potential human-health risks stemming from similar exposures. If actual risks are identified, this Team...

Increased Mercury, Reduced Insect Diversity, and Food Web impacts from Historical Mercury Mining

U.S. Geological Survey scientists are seeking to understand the impacts of mercury mining on headwater streams, organisms, and food webs, focused on potential effects from historical mining in central Idaho. Mercury associated with mine waste can leave a legacy of contamination that continues to impact stream health in culturally and ecologically important headwater streams after mining activities...
