2026-03-15T10:22:07-06:00July 7th, 2020|Tags: , |

Geosyntec is assisting the City of St. Augustine, Florida with testing wastewater for SARS-CoV-2, the virus that causes COVID-19. SARS-CoV-2 is known to survive into wastewater. Geosyntec's testing method is sound because it uses tracer material that would positively identify the presence of SARS-CoV-2 if it were present.

When a site involves volatile organic compounds (VOCs) in soil or groundwater, those chemicals can volatilize and migrate into nearby buildings presenting a health hazard to those inside. Not only that, but most buildings also contain other sources of volatile contaminants that are related to ongoing operations or consumer products. Because the same chemicals can be present in the subsurface, in chemicals used on-site, and in other products, investigation and mitigation can become complicated.

Geosyntec is an industry leader in remediating difficult-to-treat environmental impacts to soil, groundwater, and sediments through the use of specialized in situ techniques. Our practitioners are adept at expediting site investigations, optimizing remediation solutions, and accelerating site closure through a wide range of innovative technology applications. Our expertise in the implementation of new, emerging, and conventional technologies allows our practitioners to frequently bridge the gap between the development and first-to-field stages of environmental solutions. Our expertise and industry leadership in the advanced application of microbiology-based solutions for the remediation of recalcitrant contaminants in soil and groundwater has established Geosyntec’s solutions as the preferred method, especially for sites with proven resistant to conventional remediation technologies or when compared to the comparatively high costs for the application of physical and chemical technologies that achieve similar results. Two of Geosyntec’s affiliated companies provide specialized services and technologies regarding in situ treatments:
