Support for Hanford Site Cleanup Mission

EAS is using the liquid-phase Trident probe, an advanced groundwater detection and sampling tool, to determine groundwater discharge patterns and characterize pore water in the offshore portions of Columbia River (Hanford Reach), rather than relying on nearshore measurements alone. Pore water is the water between the riverbed substrates and may consist of a mixture of groundwater and surface water. The information gathered will supply verifiable pore water data for remedial action decision-making.

Work for Mission Support Alliance, Public Safety and Resource Protection

EAS is supporting the Public Safety and Resource Protection (PSRP) programs at the Hanford Site. The PSRP, directed by Mission Support Alliance for the U.S. Department of Energy, provides an array of environmental and safety-related services and recordkeeping that are critical to protecting the health and safety of Hanford workers, the public, and the environment. EAS is leading three components: Environmental Surveillance, Ecological Monitoring and Compliance, and Cultural and Historic Resources.

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.
