Your town’s water

Town water is legal. That doesn’t make it ‘clean’.

Utilities tests at the treatment plant. Water then travels miles through old and aging pipes. We’ve measured at the tap in the homes we serve, alongside the federal legal limit and a stricter health-based guideline.

Fairfield is served by the Aquarion — Eastern Fairfield County System. Each bar runs from zero to the federal legal limit; the teal line marks the stricter health-based guideline.

Two numbers, one picture. The dark line is the federal legal limit — what the EPA allows by law, with treatment cost and feasibility built in. The teal line is a health-based guideline — a stricter benchmark drawn from health research alone, like the independent EWG’s. Town water meets the law; the gap between the two is the room we work in.
When we visit, we test your specific tap. That’s the number that actually matters — and it’s the one nobody else is measuring.
