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.

Integrated science for the study of microplastics in the environment—A strategic science vision for the U.S. Geological Survey

Executive SummaryEvidence of the widespread occurrence of microplastics throughout our environment and exposure to humans and other organisms over the past decade has led to questions about the possibility of health hazards and mitigation of exposures. This document discusses nanoplastics as well as microplastics (referred to solely as microplastics); the microplastics have a range from 1 micromet

Illegal dumping of oil and gas wastewater alters arid soil microbial communities

The Permian Basin, underlying southeast New Mexico and west Texas, is one of the most productive oil and gas (OG) provinces in the United States. Oil and gas production yields large volumes of wastewater with complex chemistries, and the environmental health risks posed by these OG wastewaters on sensitive desert ecosystems are poorly understood. Starting in November 2017, 39 illegal dumps, as def

An assessment of HgII to preserve carbonate system parameters in organic-rich estuarine waters

This work assesses the effectiveness of sample preservation techniques for measurements of pHT (total scale), total dissolved inorganic carbon (CT), and total alkalinity (AT) in organic-rich estuarine waters as well as the internal consistency of measurements and calculations (e.g., AT, pHT, and CT) in these waters. Using mercuric chloride (HgCl2)-treated and untreated water samples, measurements

U.S. Geological Survey Develops Per- and Polyfluoroalkyl Substances (PFAS) Sampling Guide

USGS scientist’s published a Per- and Polyfluoroalkyl Substances (PFAS) sampling guide for personnel involved with Natural Resource Damage Assessment and Restoration (NRDAR) activities. This guide introduces individuals involved in NRDAR efforts and other investigators to key concepts and considerations when sampling different environmental media for PFAS.

Human-Related Compounds in Water Sources in the Grand Canyon Help Identify Water Flow Pathways and Highlight Potential Water Quality Changes

U.S. Geological Survey (USGS) scientists investigated the movement of human-generated chemicals, such as pharmaceuticals and per- and polyfluorinated substances (PFAS), in groundwater along the South Rim of the Grand Canyon. This research led to a better understanding of the movement of wastewater into groundwater, of complex underground flow patterns, and of chemicals present in springs near...
