What's In Chapel Hill's Tap Water?
Chapel Hill water meets all federal legal standards — but the EWG found multiple contaminants above science-based health guidelines.
Total Trihalomethanes (TTHMs)
Form when chlorine treats surface water; collectively linked to bladder cancer and reproductive harm.
Detected
44.6 ppb
EWG Guideline
0.15 ppb
Haloacetic Acids (HAA5)
Five chlorination byproducts linked to cancer and developmental harm with very low health-protective thresholds.
Detected
18.3 ppb
EWG Guideline
0.1 ppb
Dichloroacetic Acid
A haloacetic acid disinfection byproduct linked to liver tumors and developmental harm in animal studies.
Detected
11.2 ppb
EWG Guideline
0.4 ppb
Combined Radium
Naturally occurring radioactive element that concentrates in bones and is linked to bone cancer with prolonged exposure.
Detected
1.24 pCi/L
EWG Guideline
0.05 pCi/L
Nitrate
Agricultural and septic runoff contaminant linked to blue baby syndrome in infants and potential cancer risk in adults.
Detected
2.80 ppm
EWG Guideline
0.14 ppm

Common Chapel Hill Water Problems
And the systems we use to solve them.
High Disinfection Byproducts
OWASA draws from University Lake and Cane Creek Reservoir — both surface water sources prone to high TTHM and HAA formation when chlorinated. Chapel Hill had TTHMs detected at 297× EWG's health guideline.
Our solution
Whole-home carbon filtration captures chlorine and DBPs at point of entry, with RO providing the cleanest drinking water.
Naturally Occurring Radium
Chapel Hill's geology contributes naturally occurring radium to the water supply at 25× EWG's health guideline. Long-term exposure is linked to bone cancer.
Our solution
Reverse osmosis effectively reduces radium and other radioactive contaminants from your drinking water.
Agricultural Nitrate Runoff
Nitrate from surrounding agricultural land and aging septic systems reaches Chapel Hill's water supply at 20× EWG's health guideline — a particular concern for households with infants.
Our solution
RO drinking water systems remove nitrate to below detectable levels — recommended for any home with infants or pregnant women.

Water Quality in Chapel Hill, NC — Common Questions
Where does Chapel Hill get its water?
Chapel Hill's water comes from University Lake and Cane Creek Reservoir — two surface water sources that require chlorine treatment before reaching your tap. That treatment is what keeps the water pathogen-free, but it also generates disinfection byproducts (TTHMs and HAAs) detected above EWG health guidelines. Chapel Hill's water is compliant with all federal regulations. For households that want protection beyond the legal minimum — particularly those with young children or health-conscious residents — a carbon filtration system removes chlorine and its byproducts at every tap in the home.
Is Chapel Hill water hard?
Hardness in Chapel Hill runs 5–7 GPG — on the lower-moderate end for the Triangle area, but still enough to cause scale on fixtures and reduce soap performance. Older homes near the UNC campus and in Carrboro, served by aging municipal infrastructure, may notice more pronounced effects — particularly in water heaters where mineral deposits accumulate over decades and silently reduce efficiency. A water softener eliminates hardness minerals before they enter your home's plumbing, extending appliance life and improving water quality throughout.
What water filter is best for Chapel Hill homes?
For most Chapel Hill households, we recommend a whole-home carbon filter to remove chlorine and disinfection byproducts, combined with an under-sink reverse osmosis system for drinking and cooking water. If hardness testing shows elevated levels, a water softener completes the picture. We serve all Chapel Hill and Carrboro neighborhoods. Every consultation starts with a free in-home water test — we analyze your water on-site and recommend only what your home actually needs, with no obligation to purchase.
