Battelle Chlorinated Conference

Join us for the Battelle Chlorinated Conference 2026, May 31 – June 4, at the Fort Worth Convention Center in Fort Worth, TX. This international conference is the premier forum for environmental professionals, scientists, and engineers focused on the characterization, remediation, and management of sites contaminated with chlorinated and recalcitrant compounds. Attendees gain insights into the latest research, emerging technologies, and collaborative strategies that drive safer, more effective environmental cleanup practices.

Leading The Future Of Water, Remediation, And Environmental Solutions

We bring a fully integrated, science-driven approach to complex environmental challenges, combining advanced thermal remediation, water treatment, and PFAS expertise to deliver measurable results across soil, groundwater, and sediment. Through our technologies, we apply proven in situ and ex situ thermal solutions, such as electrical resistance heating and thermal conduction heating, to volatilize and remove contaminants, including PFAS, VOCs, and hydrocarbons, often achieving greater than 99.9% reduction in source zones.

Complementing these capabilities, we deliver end-to-end water and environmental services from site investigation and risk assessment through design, remediation, and long-term monitoring, leveraging multidisciplinary expertise in hydrogeology, engineering, and treatment technologies. Our PFAS approach integrates technical innovation, regulatory insight, and a broad toolkit of treatment and remediation strategies to address contamination in soil and water, helping clients manage evolving risks and liabilities associated with persistent “forever chemicals.”
