Hard water

Cities whose files cite hard or very hard water — USGS-style hardness as calcium and magnesium, not a health MCL. A salt softener is the box that actually removes it, and only if the sewer allows brine.

Category: aesthetic
EPA status: No EPA primary MCL. USGS classes water as soft (0–60 mg/L as CaCO3), moderately hard (61–120), hard (121–180), and very hard (more than 180).
Typical sources: Dissolved calcium and magnesium from carbonate rock and some surface-water blends. Common in groundwater and in Southwestern city supplies.

Hard water is the hardness file with the city list pointed at scale and soap, not at a toxin story.

A salt-based softener removes calcium and magnesium. A salt-free conditioner does not. Whole-house carbon does not. Check whether a brine tank is even legal before you price one.

The list below uses hardness rows and hardnessClass: hard or varies already on city files. Unknown hardness — the opened report did not print grains — is omitted so we do not invent a class.

Cities on file

Only numbers and notes already printed on a city Markdown file. We do not invent a detection to fill this list.

Highest cited numbers on file

Only values already printed on a city file. Sort is the optional numeric field, not a new lab result.
