2025 water quality results
Highlights use the B.T. Brown plant column in CCWSA’s report. They are not an average across purchased supplies and do not represent Newnan Utilities retail customers.

Your provider needs its own report.
Continue with your home details for general filtration guidance. We will not use another utility’s numbers as your result.

In drinking water, ppm ≈ mg/L, ppb ≈ µg/L and ppt ≈ ng/L. Calculated hardness in grains per US gallon (gpg) = mg/L as CaCO₃ ÷ 17.118, rounded to one decimal. ND means below the reporting limit, not zero.
MCL means a regulatory contaminant limit; MRDL is a disinfectant limit. Lead and copper use tap-sampling action levels. TTHM and HAA5 compliance is assessed using running averages at specific locations, not the highest single sample.
PFAS results depend on the compound, sample location, year and reporting limit. A missing result or nondetect is not proof of zero PFAS. EPA PFAS benchmarks and implementation ↗

More about your local water
What this means for your home
Review CCWSA’s B.T. Brown plant results alongside an explanation of its multiple water supplies.
Highlights use the B.T. Brown plant column in CCWSA’s report. They are not an average across purchased supplies and do not represent Newnan Utilities retail customers.
A useful local question
Are these results also for Newnan Utilities customers?
No. The highlights use the CCWSA report’s B.T. Brown plant column. CCWSA also purchases water from other suppliers, but a Newnan Utilities retail customer should use Newnan’s own report.
Sources and methodology
Results retain the utility, sample year, units and comparison used in the source. Hardness is shown separately as a utility measurement, utility guidance or regional estimate. USGS categories describe mineral content, not drinking-water safety.
Different name on your water bill?
Use the published report for your own retail water system. These sources can help identify the right report; a county or ZIP alone cannot confirm service.
