U.S. Geological Survey
Our Nation's environment -- the air, water, soil, and plant and animal life -- is constantly changing as natural processes and human actions affect it.
USGS activities in the environment theme area include studies of natural physical, chemical, and biological processes, and of the results of human actions; the goal is to provide the understanding and scientific information needed to recognize and mitigate adverse impacts and to sustain the environment. Activities include data collection, long-term assessments, ecosystem analysis, predictive modeling, and process research on the occurrence, distribution, transport, and fate of contaminants as well as the impacts of contaminants on biota.
