Drinking water in Greenville
Greenville's reservoirs sit in protected mountain watersheds, and Greenville Water publishes its monitoring results in an annual water quality report. RO is an optional extra barrier for drinking and cooking water, usually chosen by households focused on PFAS or on lead from older home plumbing.
PFAS and Greenville 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 Greenville 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.

Frequently asked questions
Does reverse osmosis make sense with water this soft?
Hardness has little to do with it. Reverse osmosis is chosen for contaminants like PFAS, lead and nitrates, and some systems add minerals back for taste.
Does reverse osmosis remove PFAS?
Reverse osmosis is one of the most effective home treatments for PFAS. Certified systems list which PFAS they were tested to reduce.
Where does the system go?
Under the kitchen sink, with its own faucet. It can also feed a refrigerator or ice maker.
