Support for Hanford Site Cleanup Mission

EAS is using the liquid-tip <a href='/assets/docs/EAS-GroundwaterMapping.pdf'>Trident probe</a>, an advanced groundwater upwelling detection and sampling tool, to determine groundwater discharge patterns and characterize porewater in the offshore portions of Columbia River, rather than relying on nearshore measurements alone. Porewater is the water between the riverbed substrates and may consist of a mixture of groundwater and surface water. The information gathered will supply verifiable porewater data for remedial action decision making.

Support for the Natural Resource Damage Assessment of the Deepwater Horizon Oil Spill in the Gulf of Mexico

EAS provided support to NOAA's work to assess the damage to natural resources resulting from the 2010 oil spill in the Gulf of Mexico. In this project EAS was recognized by NOAA for playing a key role in developing and performing the sampling operations both on land and onboard research vessels in the Gulf, and in developing training protocols for sampling.
