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 ↗

What this means for your home
Compare Carroll County Water Authority with the separate City of Carrollton water system.

A useful local question
Are Carroll County Water Authority and Carrollton the same provider?
No. Select the exact name on your bill. The authority and the city publish separate reports with different disinfectant and disinfection by-product results.
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.
