Columbus water is moderately hard after the utility softens it, and it carries a chlorine residual. Private wells around the city are a different supply: iron, sulfur, and higher hardness are the usual reasons to test them. The City of Columbus says it softens finished water to about 120 parts per million (about 7 grains per gallon) on average, and calls that moderately hard. The city leaves some hardness in on purpose, because very soft water can corrode home plumbing.
The visit checks hardness, chlorine, TDS, iron, and odor. That is enough to choose between a softener, a whole-home carbon filter, a reverse osmosis drinking-water system, a well-water setup, or no equipment. It is not a certified lab report for bacteria, nitrate, lead, or PFAS. When those are the question, we say so.
We do not publish star ratings, review counts, a license number, or years in business on this site. The useful record is your own test and your utility's water report.
