Groundwater Assessment and Remediation
Geosyntec provides specialized site assessment and remediation services to public and private sector clients in North America, Europe, Asia, and Australia. We employ technology-based strategies to meet our clients’ stewardship, financial, and compliance goals to remediate soil and groundwater contaminants. Our site assessment and remediation specialists form one of the preeminent practices in North America and include individuals whose applied research continues to redefine the state-of-the-practice internationally.
Our international groundwater assessment and remediation practice focuses on developing solutions for our clients’ most challenging assignments involving metals (chromium, arsenic, lead), petroleum hydrocarbons (diesel, gasoline, jet fuel), and chlorinated organic chemicals (chlorinated solvents). We are among the international leaders in the application of in situ technologies such as bioremediation, bioaugmentation, permeable reactive barriers, and chemical oxidation for remediating a wide variety of contaminants. We specialize in the remediation of not only “traditional” recalcitrant compounds such as chlorinated solvents but also emerging contaminants such as 1,4-dioxane (a chemical that prevents the breakdown of chlorinated solvents), perchlorate (an oxidizer in pyrotechnics and propellants), NDMA (N-nitrosodymethylamine - primarily associated with the development and production of liquid rocket fuels), MtBE (methyl tert-butyl ether - a gasoline oxygenate), and TBA (tert-butyl alcohol – a gasoline oxygenate), and a range of biopharmaceutical constituents.
Geosyntec practitioners are adept at efficiently characterizing sites, even those with complex groundwater flow regimes, and developing remediation programs that take advantage of the latest proven technologies. For example, a number of our hydrogeologists specialize in modeling the fate and transport of contaminants through fractured bedrock, karst bedrock, and highly anisotropic media. Our engineers, earth scientists, and microbiologists recently applied their expertise in fate and transport modeling, zero-valent iron (ZVI) treatment technology, and geotechnical engineering to design and construct a ZVI permeable reactive barrier (PRB). It was the first to be included in a U.S. EPA CERCLA Record of Decision and the largest ZVI PRB application at the time in North America. Our innovative applications of proven technology saved the site owners millions of dollars compared to the prescriptive remedies available at the time.
