PFAS Water Treatment and Filtration in Stamford, CT

Property owners searching locally need a provider that can diagnose the complete water system rather than treating one symptom in isolation. Duncan Water Systems provides PFAS-focused water testing coordination and treatment system design for private well owners, commercial facilities, institutions, industrial properties, and decision makers concerned about per- and polyfluoroalkyl substances in drinking or process water. The work is designed to resolve confirmed or suspected PFAS, uncertainty about which compounds are present, changing treatment performance, inappropriate off-the-shelf filters, and the need for a defensible long-term management plan. Based at 24 Larkin Street, Stamford, CT 06907, Duncan Water Systems serves Stamford, lower Fairfield County, and clients across Connecticut and the Northeast. The company has provided water supply and treatment services since 1952 and works across residential, commercial, industrial, and municipal applications. That broad field experience matters in Fairfield County, where properties may be supplied by private wells, municipal water, or a combination of infrastructure with very different pressure and water-quality characteristics. Local service also means the team can evaluate the complete site, coordinate testing, and recommend equipment that fits the building instead of forcing the building to fit a catalog package. Common applications include private wells, residential drinking water, commercial buildings, schools, institutions, industrial source water, process water, and systems requiring a multi-barrier contaminant-reduction approach. Depending on the project, the solution may combine targeted laboratory testing, activated carbon, specialized ion-exchange resins, reverse osmosis, lead-lag vessel configurations, prefiltration, monitoring points, media change planning, and post-treatment verification. This integrated approach is especially valuable when one water issue affects another. For example, sediment or iron may need to be addressed before ultraviolet disinfection or reverse osmosis; low pressure may be caused by a pump, tank, restriction, or treatment system; and storage may be needed when a well cannot keep pace with short periods of high demand. Evaluating the sequence of treatment and supply components helps protect downstream equipment and deliver more consistent results at every fixture or process connection. A typical project starts with a site conversation and review of the symptoms, water source, existing equipment, and performance goals. The next step may include water sampling, flow and pressure testing, infrastructure inspection, or review of drawings and operating data. Duncan Water Systems then develops a recommendation around specific PFAS compounds and concentrations, competing organic matter, flow, empty-bed contact time, resin or carbon capacity, pressure loss, breakthrough monitoring, residual disposal, and applicable federal, state, and local requirements. Equipment is selected for the required duty, not simply for the lowest initial price. Installation is coordinated with piping, electrical, drainage, controls, storage, and other treatment stages. Startup includes verification that the system is producing the intended flow, pressure, and water quality. For more complex commercial and industrial work, the scope can include engineering partnerships, permitting support, detailed specifications, monitoring, and operator training. The advantage of this method is long-term performance. Incorrectly sized equipment can create pressure loss, frequent regeneration, short cycling, unnecessary energy use, early media exhaustion, or poor contaminant removal. A properly engineered system is easier to maintain, more efficient to operate, and better able to respond to peak demand. Duncan Water Systems also considers service access, replacement planning, and total cost of ownership. Where applicable, designs account for Connecticut DEEP requirements, the EPA Safe Drinking Water Act, local health and building standards, and NSF/ANSI-certified materials. Recommendations are based on the specific application and test data; no single treatment technology removes every possible contaminant. Consult Duncan Water Systems for testing-led PFAS treatment that includes verification and a plan for ongoing monitoring and media management. Duncan Water Systems can be reached at (203) 323-0556. The Stamford office is located at 24 Larkin Street, Stamford, CT 06907. A consultation can clarify the likely cause of the issue, the testing or measurements needed, and the most efficient next step. By combining local responsiveness with water-system engineering, treatment expertise, installation, and lifecycle support, Duncan Water Systems helps clients achieve reliable water quality, pressure, storage, and supply with a system designed for the way the property actually operates.
