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.

Projects have included:

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

• Massachusetts Military Reservation (MMR) flow and transport models of munitions constituents in the saturated and unsaturated zones

• Herbert Hoover Dike cut-off walls at Lake Okeechobee (a Dam Safety Action Classification or DSAC 1 impoundment)

• Afghan base water supply evaluation

• Groundwater supply study for Delaware

• Extensive HTRW modeling for both active and inactive DoD installations, the Formerly Utilized Sites Remediation Program (FUSRAP), and Superfund and RCRA sites in EPA Regions I, II, and III

• Wetland permit issues associated with mining and groundwater extraction

• Navigation studies related to dredging and dredge disposal

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