Drinking water in Conway
Conway's water is river water from the Great Pee Dee watershed, treated at GSWSA's Bull Creek plant. Surface water carries more organic matter than deep groundwater, which is why utilities monitor disinfection byproducts such as trihalomethanes. An RO system and its carbon stages reduce those byproducts along with PFAS and dissolved solids at your kitchen tap.
PFAS and Conway water
The EPA set the first national drinking water limits for several PFAS in 2024, and utilities publish their monitoring in annual water quality reports. Check Conway city water's latest report for your area; RO adds a second barrier at your kitchen tap.
What reverse osmosis reduces
Certified systems reduce dissolved solids, lead, many PFAS compounds, nitrates and arsenic, and their carbon stages take out chlorine or chloramine taste. Look for certification to NSF/ANSI 58 for the contaminants you care about. How reverse osmosis works.
What happens at your free test
Your free test measures hardness, chlorine or chloramine, iron, pH and total dissolved solids at your tap, and you keep the written report. We recommend a reverse osmosis system only if your results call for it. How the free test works.
