Hanford Washington Superfund Site

From 2008 to 2013 CMA has been working with the US Dept of Energy and Environmental Assessment Services to quantify migration of contaminants from the Hanford reservation to the Columbia River. CMA developed a 600 pound driving frame for use in the hard bottom, swift current environment of the Columbia. Using this frame and adapting existing trident deployment techniques, CMA was able to sample porewater over 1,000 locations from 2008-2014.
