Common Cary Water Problems
And the systems we use to solve them.
Disinfection Byproducts
Cary's surface water source makes it susceptible to chlorination byproducts. TTHMs and HAAs were detected at up to 458× EWG's health guideline.
Our solution
Whole-home carbon filtration removes chlorine and DBPs at entry, while RO handles drinking water.
Moderate Hard Water
Cary water is moderately hard, causing spotty dishes, scale on fixtures, reduced appliance efficiency, and dry skin in the shower.
Our solution
A water softener or salt-free conditioner solves scale and hardness for the whole home.
PFAS "Forever Chemicals"
Cary has some of the highest PFOA levels in the Triangle — 2.86 ppt, or 32× EWG's health guideline. These chemicals are linked to kidney cancer and cardiovascular disease.
Our solution
Reverse osmosis removes PFAS from drinking water with up to 99% effectiveness.

Water Quality in Cary, NC — Common Questions
Does Cary have hard water?
Cary's water comes from Jordan Lake, treated at the Town of Cary's Jordan Lake Water Treatment Plant. Hardness runs 5–8 grains per gallon — moderate, but enough to leave mineral deposits on fixtures and affect everyday water quality. Cary's newer planned communities — Amberly, Preston, and Lochmere — often feature high-end appliances and finishes that are particularly susceptible to hard water damage. Tankless water heaters are especially vulnerable; a softener installed at the point of entry is one of the best things you can do to protect that investment and maintain manufacturer warranties.
Is Cary's tap water quality good?
Cary's water meets all federal standards and is generally well-managed. The EWG identified 8 contaminants above their science-based health guidelines, primarily disinfection byproducts from the chlorine treatment process and trace PFAS from Jordan Lake's watershed. For families with young children, pregnant women, or anyone who prefers not to rely solely on regulatory minimums, an under-sink reverse osmosis system delivers water that meets the strictest available standards — removing over 99% of contaminants at the point of use.
What water filtration do most Cary homes use?
Most Cary homeowners we work with choose one of two setups: a whole-home carbon filter paired with a water softener for hardness and chlorine removal, or the complete system that adds an under-sink reverse osmosis unit for drinking and cooking water. We start every job with a free in-home water test so we know exactly what we're dealing with — no guesswork, no upselling. We serve all of Cary and can typically schedule same-week installation.
