Emerging Contaminants:
PFAS, 1,4-Dioxane—and More
Applying scientific expertise to address potential
new chemical impacts to ecological and human health
- The Summary
- Our technical experts provide comprehensive solutions to multi-faceted problems related to PFAS, 1,4-dioxane and other emerging groundwater contaminants, with an emphasis on: remediation strategies, data quality, toxicology, remedial cost estimating, natural resource damage assessments, and laboratory method development.
- The Client
- Government agencies, confidential clients
- The Rundown
- We conducted a series of 1,4-dioxane treatability studies in Colorado to evaluate the effectiveness of various remedial technologies, successfully remediating 1,4-dioxane.
- We developed an investigative approach to determine the extent of PFAS in soil and groundwater related to a manufacturing plant, and provided detailed cost estimates for investigating and mitigating PFAS in environmental media at the plant and in surrounding areas, including residential well mitigation systems.
- We prepared a PFAS-based risk assessment supporting the redevelopment of a former military base, successfully gaining state-approved, provisional compliance criterion for PFAS compounds.
- We provided critical analytical chemistry and quality assurance input to USEPA during the development of Method 8327, which was released in draft form in June 2019 and is capable of measuring 24 PFAS compounds in groundwater, surface water, and wastewater.
- We conducted a comprehensive review of historical file materials for a large commercial airport, identifying all potential source areas, storage methods and management procedures for PFAS, including aqueous film-forming foam (AFFF). The assessment clearly identified potential liabilities associated with PFAS at the airport.
