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 is an enforceable contaminant limit; MRDL is a disinfectant limit. A secondary guideline concerns aesthetics. TTHM/HAA5 compliance uses locational running annual averages; read the utility’s notices as well as individual results.

PFAS results are compound-specific. Source monitoring, entry-point samples and tap tests are different. A detected result does not identify every PFAS compound or establish the level at your home. Read the original report for context and current utility notices. EPA PFAS benchmarks and implementation ↗

More about your local water

What this means for your home

Muncie combines river, reservoir and groundwater sources. The report lists chlorine and chloramines separately, so the two disinfectant measurements are not added together.

The utility’s copper percentile is below its action level, but one sampled home was above it. That difference is why system-level sampling cannot replace a test of plumbing at a specific home.

A useful local question

What should a Muncie filter and softener address?

Match filtration to the documented chloramine treatment and your other reduction goals. A softener addresses the hardness minerals; the utility’s reported level is 354 ppm, with a 230–432 ppm range.

Sources and methodology

We keep each utility’s results separate, show the reported sample year, and distinguish averages, maxima and tap-sampling percentiles. Hardness classifications use USGS ranges. Missing data stays unknown.
