Groundwater Assessment and Remediation

Our expertise in efficient site characterization, including sites that exhibit complex groundwater flow regimes, has distinguished our firm and practitioners as leaders in the assessment and remediation of groundwater. Our practitioners are highly skilled in addressing a broad suite of contaminants, including metals, chlorinated organic chemicals, petroleum hydrocarbons, and emerging contaminants, and utilize award-winning, technology-based remediation strategies that are often first to field. Many of our hydrogeologists specialize in modeling the fate and transport of contaminants through the most difficult types of media, including fractured and karst bedrock.

We work closely with our clients to fully understand their specific challenges and assist them in successfully navigating the complex regulatory environments that projects may encounter. Our engineers and scientists guide them through every step and develop precise characterization and diagnostic tools that improve their ability to achieve site-specific remedial action objectives within a reasonable time frame utilizing cost-effective solutions.

Once a site has been characterized, we are adept at applying ex situ and in situ remedial technologies, long-term monitoring, and other site management strategies. While we are highly experienced in conventional approaches and technologies, we are practice leaders in the application of state-of-the-art in situ remedial technologies, including:

  • Bioremediation and bioaugmentation;
  • Chemical oxidation;
  • Chemical reduction; and
  • Thermal remediation.

Advancing the State of the Practice

Geosyntec continues to partner with leading academic institutions in the development of next-generation characterization and treatment technologies. Among the technologies currently in development, testing, or analysis by Geosyntec and its subsidiaries are:

  • Electrokinetic enhanced amendment delivery, an innovative approach that uses electrokinetic mechanisms to promote migration of electron donors, electron acceptors, and bacteria for in situ bioremediation (EK-bio) or oxidants for in situ chemical oxidation (EK-ISCO);
  • Self-sustaining Treatment for Active Remediation (STAR), a smoldering combustion technology for the efficient destruction of hydrocarbons such as coal tars and oils using either an ex situ or in situ application;
  • Zero-valent metal formulations to treat recalcitrant compounds (e.g., polychlorinated biphenyls, 1,2,3-trichloropropane);
  • New microbial consortiums capable of degrading compounds such as carbon tetrachloride and 1,1,2,2-tetrachloroethene (TeCA);
  • Sustainable, low carbon footprint pump-and-treat systems, using solar power to operate the systems;
  • and 3-D visualization software applications that aid in the assessment of dense non-aqueous phase liquids and other groundwater impacts.

We have developed comprehensive guidance on the effective management of contaminated groundwater to address environmental impacts for use by regulatory agencies in the United States and Europe, including the U.S. Environmental Protection Agency (EPA), the Swedish Environmental Protection Agency, the Danish Environmental Protection Agency, the U.S. Department of Defense (DoD), the National Research Council (NRC), the Electric Power Research Institute (EPRI), the American Petroleum Institute (API), and the Interstate Technology and Regulatory Council (IRTC).
