Hard water in Southwest Florida: what to test for
White spots on glasses, crusty showerheads, soap that never seems to rinse off. Those are the usual signs of hard water, and they are some of the most common reasons homeowners in Lee, Collier, and Charlotte counties ask us to look at their water. Before anyone recommends equipment, the useful first step is finding out what is actually in the water at your tap.
What “hard water” means
Hardness is mostly dissolved calcium and magnesium. It is an aesthetic and maintenance issue: it leaves scale on fixtures, glass, and inside water-using appliances, and it makes soap less effective. Penn State Extension’s guide to water softening explains how hardness is measured and how softeners work.
Signs you may notice at home
- Spots or film on glasses and shower doors
- White crust on faucets, showerheads, and around drains
- Soap and shampoo that do not lather well
- Scale building up in a water heater, which can show up as rumbling or sediment when it is flushed
City water vs. well water
If you are on a public utility, your provider publishes an annual water quality report, called a Consumer Confidence Report (CCR). The EPA explains what CCRs cover. Local examples include the Lee County Utilities water quality report, the Collier County drinking water quality report, and the Charlotte County Utilities CCR. Many cities, including Bonita Springs, Fort Myers, and Cape Coral, have their own suppliers that publish their own reports.
Private wells are not covered by a utility report. Well water in inland areas such as Lehigh Acres, Golden Gate Estates, and parts of Charlotte County can be a very different starting point from city water in town, so a test matters even more.
What to test for
- Hardness, to know whether a softener makes sense and how to size it
- pH
- Iron and other minerals, because iron changes what equipment should go in first
- Odor, if you smell sulfur, so the source can be tracked down before anything is installed
A softener treats hardness. It is not the fix for a rotten-egg smell or heavy iron staining, which usually call for filtration. That is why the order of equipment should come from the test. Read more in our guide to iron and sulfur in well water.
What happens at our free water test
We come to the house, check hardness, measure pH, and look for iron and other minerals, then sit down with you and go over the results in plain language. If the water is in good shape, we will tell you so. If it is not, we explain the options, such as a water softener, iron and sulfur filtration, or whole-home treatment. The on-site test is a field check, not a laboratory report; if a question needs a lab, we will say so. Details are on the free water test page.
