Connect With a PFAS Expert
PFAS decisions carry long-term consequences. Onterris helps organizations move from uncertainty to action with the testing, treatment and remediation expertise needed to manage PFAS confidently across water, waste and site programs. From early evaluation through deployment and long-term optimization, we connect scientific rigor with field-ready solutions that hold up in practice.
PFAS treatment works best when data, deployment and long-term stewardship are planned together. Onterris combines advanced PFAS analysis, site-specific treatment evaluation, modular deployment and patented treatment innovation to help clients reduce risk and move faster with confidence.
Clarity for one of the most persistent environmental challenges
PFAS treatment is rarely one-size-fits-all. Onterris combines testing, treatment expertise and proven technologies to address complex water chemistry, site constraints and evolving requirements, helping you reduce uncertainty, select the right approach and achieve reliable, long-term performance.
Understand What’s in Your Water
Advanced PFAS analysis and scientific interpretation characterize water chemistry, contaminant profiles and site conditions to inform treatment selection and system design.
Prove Performance Before You Invest
Bench and pilot testing evaluates treatment under site-specific conditions to validate performance, optimize operating parameters and generate data for full-scale design.
Reduce PFAS Waste and Disposal Burden
PFAS concentration technologies, including FOAM-X™, reduce residual volumes and downstream disposal requirements, helping improve treatment efficiency and manage lifecycle costs.
Achieve Reliable, Long-Term PFAS Removal
Advanced adsorption technologies, including SORBIX™ Pure and SORBIX™ RePURE, remove PFAS, including challenging short-chain compounds, with treatment tailored to water chemistry and operating requirements.
