The U.S. Geological Survey Toxic Substances Hydrology Program provides objective scientific information on and the environmental pathways of chemical and microbial contaminant exposures. In collaboration with the Contaminant Biology Program as well as public health experts and others, the fundamental datasets and other knowledge products are developed to understand the implications of environmental contaminant exposures on the health of humans and other organisms.
The Program has several investigations of national concern.
Data from studies on the occurrence and distribution of environmental contaminants
Information on field methods, measuring environmental contaminants, models tools, geophysical methods, tracer test, and management and remediation alternatives.
