What Hendersonville's Water Means for Your Home
Hardness: 105 PPM - Low Concern
Hendersonville's water is firmly in the moderate range at 105 PPM. You'll see some spotting on glassware and a film on shower doors over time, but it's not the kind of hardness that demands a full softener. A salt-free conditioner is worth considering if you have a tankless water heater or high-end fixtures.
Contaminants & Safety
Disinfection byproducts are the notable finding here. Hendersonville's water has TTHMs at 44 ppb and HAA5 at 34.6 ppb — both within legal limits, but the EWG health guidelines are far stricter. These byproducts form when chlorine reacts with organic matter during treatment. A whole-house activated carbon filter reduces both chlorine and its byproducts. Want the full picture? Request your utility's annual Consumer Confidence Report.
What's in the Treatment Process
Hendersonville's surface water supply requires heavy chlorination to stay safe — but that creates a tradeoff. The treatment process generates disinfection byproducts: TTHMs at 44 ppb (55% of the legal limit, but 293x the EWG guideline) and HAA5 at 34.6 ppb (58% of the legal limit, but 346x the EWG guideline). These are within legal limits, but the EWG sets much tighter thresholds based on cancer-risk research. A whole-house activated carbon filter reduces both chlorine and byproducts.
Chromium-6 was detected at 0.109 ppb, which is 5.4x the EWG health guideline. There's no separate federal limit for chromium-6, only total chromium. A reverse osmosis system is the most effective removal method. All measurements are within federal legal limits. The EWG guidelines represent a more conservative, health-based standard.

About Hendersonville's Water Supply
Water Utility: Hendersonville Utility District
Water Source: Old Hickory Lake (Surface Water)
Population Served: 130,411
Hardness: 105 PPM (6.1 grains per gallon)
Hendersonville's drinking water comes from surface sources — Old Hickory Lake. Surface water requires more extensive treatment than groundwater, including coagulation, filtration, and disinfection. This heavier chlorination is why disinfection byproducts tend to be higher in surface-supplied systems. On the upside, surface sources often deliver softer water than deep aquifers. The system serves 130,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request Hendersonville Utility District's Consumer Confidence Report (CCR) or test your own tap.
