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
Atlanta and North Fulton publish different results.
The river is shared, but treatment and sampling locations differ. North Fulton’s plant is in Johns Creek. An Atlanta mailing address does not establish which utility sampled your water.
A useful local question
Use the North Fulton report when Fulton County Public Works supplies your water. Atlanta’s fluoride, chlorine and lead figures describe a different system.
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.
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.
