Health and Water Research

EPA conducts this research because waterborne illnesses continue to threaten American public health from sewer overflows and waterborne pathogens.

High-Throughput Toxicokinetics (httk) R Package

Access the httk R Package: EPA researchers developed multiple toxicokinetic models within an R software package called high-throughput toxicokinetics (httk) to estimate chemical concentrations in humans.

Indicators Used in the National Aquatic Resource Surveys

National Aquatic Resource Surveys use biological, physical, chemical and recreational indicators of water quality.

National Port Strategy Assessment: Reducing Air Pollution and Greenhouse Gases at U.S. Ports

The assessment finds that air pollution at the Nation's ports can be significantly reduced by implementing currently available strategies and technologies to reduce emissions of harmful pollutants from diesel vehicles and engines.

Indicators: Fish Fillet Tissue Contaminants

Fish tissue contaminants are indicators of toxic chemicals in the water. Mercury, PCBs, chlordane and DDT concentrate in fish and pose health risks to people and animals that consume them.

Indicators: Soil Chemistry

The chemical makeup of the soil can provide information on wetland condition, wetland water quality and services being provided by the wetland ecosystem. Analyzing soil chemistry reveals if the soil is contaminated with a toxic chemical or heavy metal.

Hazard Mitigation Module

Watershed Academy module: Creating Co-Benefits Through Hazard Mitigation Planning and Water Resource Management

Indicators: Salinity

Salinity is the dissolved salt content of a body of water. Excess salinity, due to evaporation, water withdrawal, wastewater discharge, and other sources, is a chemical sterssor that can be toxic for aquatic environments.

For EPA Grantees Proposing Human Subjects Research

More information for EPA Grantees proposing Human Subjects Research in their projects to receive approval by the EPA Human Subjects Research Review Official before any work involving human subjects can begin.
