PFAS Modeling & Testing

Sentinel manufactures basic and fully automated pilot test skids for rent, lease, or purchase.  Sentinel also supports customers with four distinct system modeling and pilot study approaches, each designed to address specific project goals and site conditions.  We collaborate closely with our clients to develop comprehensive long-term operations and maintenance (O&M) strategies, going beyond initial media bed life to ensure sustainable, cost-effective system performance over time. Learn more here.

PFAS Treatment – Custom Treatment Systems

At Sentinel, our approach encompasses the entire treatment process—from raw water influent to system entry for distribution. We partner with utilities and design engineers to address every aspect of the system design, with a strong focus on CAPEX, OPEX, and operational functionality.

Every component—including pumps, pretreatment, pressure vessels, and enclosures—is carefully selected based on site-specific conditions to ensure optimal performance. This integrated, utility-first design approach enables faster implementation and more cost-effective PFAS treatment solutions. Learn more here.
