The North Atlantic Division Regional Center of Expertise (RCX) for Groundwater Modeling provides full-service solutions for groundwater related issues. Although the RCX was officially recognized in 2009, the team has been solving groundwater problems since 1994.

Some past projects have included:

• Everglades restoration density-dependent models to evaluate aquifer storage and recovery (ASR)

• Joint Base Cape Cod flow and transport models of munitions constituents in the saturated and unsaturated zones

• Groundwater models to evaluate Herbert Hoover Dike cut-off walls at Lake Okeechobee (a Dam Safety Action Classification or DSAC 1 impoundment) in Florida

• Afghan base water supply evaluation using a groundwater model

• Mobile Harbor groundwater modeling to assess potential increases in saltwater intrusion due to dredging near the water supply wells for Dauphin Island in Alabama

• HTRW modeling for DoD installations, the Formerly Utilized Sites Remediation Program (FUSRAP), FUDS, IRP, BRAC, Superfund and RCRA sites in EPA Regions I, II, and III

• Wetland permit issues associated with mining and groundwater extraction

• Developing groundwater models to evaluate seepage and relief wells at several levees along the Mississippi River

The Regional Center of Expertise (RCX) for Groundwater Modeling is a multidisciplinary group of modelers, hydrogeologists, geologists, chemists, risk assessors, GIS experts, and engineers.
