The Wolf Creek Dam is located on the Cumberland River in the western part of Russell County, Kentucky. The dam provides hydroelectric power generation, flood management, water storage for year-round navigation, and water recreation. In addition, the dam serves as part of U.S. Highway 127.
The new 110' x 600' Chickamauga Lock is being designed and constructed by the Nashville District, U.S. Army Corps of Engineers (USACE). The Judy Company (JC) has been contracted to construct a barrier wall consisting of an angled grout curtain.
Since 1956, the Tenneco Automotive facility has been producing automotive components at the project location near Hartwell, Georgia. The site is underlain by fractured bedrock and highly anisotropic groundwater flows due to subsurface lineaments.
The LCP Holtrachem Site is a former chlor-alkali manufacturing facility which used the mercury cell process, located along the Cape Fear River near the coast of North Carolina. This ecologically sensitive area serves as a fishery, fisheries nursery area, and spawning area for the endangered short nosed sturgeon.
The Bernuth-Lembcke site is a 3.5-acre parcel of land situated in an industrial setting near the Savannah River in Savannah, Georgia. The site PRPs include Norfolk Southern Railway (NS) and Honeywell.
At the Colonial Pipeline Gaffney booster station site, the overburden and bedrock aquifers beneath the site have been impacted with dissolved petroleum hydrocarbons associated with historical operations and spills at the facility. A methyl tertiary butyl ether (MTBE) and benzene plume had migrated to both the north and the south part of the site because of the groundwater divide near the spill area.
The County of Santa Barbara in southern California needed to enhance its available data resources with which to manage its stormwater runoff water quality. The County felt that there were significant gaps in existing data that it needed to make long-range planning decisions.In particular, there were significant data gaps in their GIS system, such as detailed estimates of impervious cover, recent high quality multi-spectral orthophotography, etc. These data were needed in order to facilitate the implementation of stormwater best management practices, or BMPs. Ultimately, with limited funds with which to implement BMPs, the County's goal was to prioritize which areas needed attention first in terms of retrofits, new nonpoint source water quality control, etc.

The Gowanus Canal Superfund Site is undergoing extensive remediation that is expected to take 10 years. Remediation includes dredging, in situ stabilization (ISS), capping, bulkhead replacement, and more.
Geosyntec provides technical project management to the Baldwin Park Operable Unit (BPOU) cooperating respondents (CRs) for this Superfund site, including the characterization, hydraulic capture, and treatment of site contaminants of concern (COCs). Site COCs include chlorinated volatile organic compounds (VOCs), perchlorate, N-nitrosodimethylamine (NDMA), and 1,4-dioxane. To meet project objectives, Geosyntec performs 3D groundwater-flow and contaminant-plume modeling alongside water-quality-trend evaluations, data analysis and reporting, and site operation and maintenance.
