Contaminant Plume Geochemistry and Microbiology

Geochemical and microbiological characterization of processes related to contaminant plume migration and evolution

Understanding the geochemical and microbiological processes that control the migration, shape, and size of contaminant plumes is key to developing cost-effective remediation plans. Many USGS Toxic Substances Hydrology (Toxics) Program scientists have studied a variety of contaminant plumes with the goal of understanding in a holistic sense how contaminant plumes interact with ground water, microorganisms, and aquifer materials. The information presented on this page cuts across lines drawn by individual investigations and projects so that information on the contaminant plume geochemistry and microbiology can be presented in one place.

Investigations and Research Activities

Fact Sheets

A handful of sand from aquifer sediments on western Cape Cod, MA. The surfaces of these quartz grains are covered by coatings containing iron and aluminum oxides and silicates. Arsenic in the coatings can be released by changes in chemical conditions caused by contaminant plumes such as the plume of treated sewage that is the subject of the Toxic Substances Hydrology Program's investigation on Cape Cod
