Characterizing Mollusks and Other Macro-Invertebrates at the Hanford Enclosure 

EAS surveyed more than 40 locations in the riparian and aquatic zones between the 100 and 300 Areas of the Hanford Site to gather information on mollusks and other macro-invertebrates for the DOE.

EAS located, identified, collected, and measured mollusks, including rare species such as the pebbles snail and spring snail, and characterized their habitats. We also sampled crayfish, mayfly larvae, caddisfly larvae, and worms. The purpose of this project was to measure contaminant uptake and evaluate species diversity, abundance, and biomass. The information was used to support federal and state decisions on risk management.
