Lehigh Acres well water: iron, hardness, sulfur, and tannins

Start with the source

Lehigh Acres is in eastern Lee County. Some homes use a private well and some are on a public water system. The notes below are for well water.

If a utility supplies your water, start with the latest water-quality report from that utility. A rotten-egg smell that shows up only in the hot water can still come from the water heater on either kind of supply. The sulfur guide covers that check.

This is practical guidance from the directory team. It describes problems that show up on wells in this area. It is a starting point for your own well, after a test.

Iron

Iron can leave yellow, orange, or brown stains on fixtures, toilets, and laundry, sometimes with a metallic taste. Clear water that turns color after it sits means the iron was still dissolved at the tap. Color or specks that are already there when you open the faucet mean the iron has already oxidized, or that something else is discoloring the water.

Iron bacteria can leave a slimy rust-colored film. That film is a nuisance in the plumbing. A bacteria test for coliforms is a separate sample.

A water softener can pick up a light load of dissolved iron while it removes hardness. Heavier iron, iron that has already turned into particles, or iron mixed with organic color needs oxidation and filtration. Iron can also clog softener resin, so the order of the equipment matters. The test is what separates those cases.

Hardness

Hardness is dissolved calcium and magnesium. It leaves chalky scale on fixtures and inside water heaters, spots on glass, and soap that feels like it never rinses. Scale is a nuisance and a reason heaters work harder. It says nothing by itself about bacteria.

A conventional softener removes those minerals. Disinfection, sulfur, and tannins are different jobs. Other devices are sold to reduce scale while leaving the minerals in the water. Ask what was measured, what the device changes, and what maintenance it needs.

A regional map cannot tell you the hardness at one house. Ask for a hardness result from your well.

Sulfur

A rotten-egg smell points to hydrogen sulfide. It can come from the well, from bacteria living in the plumbing, or from a reaction inside the water heater. Smell in the hot water only, and smell in both hot and cold, point to different work.

The sulfur guide walks through that check and the usual treatment options: aeration, oxidation, and carbon. Ask for a coliform test on a private well when sulfur is the complaint. The smell and the bacteria result answer different questions.

Tannins

Tannins are organic color from decaying plants. The water can look like weak tea. Some shallower Florida wells pick this up. The tint can resemble iron, and a glass of water cannot settle which one you have.

Tannins show up as color and as something that can stain. They can also foul softener resin and some iron filters, so they belong on the test before that equipment is sized. Light color is sometimes handled with carbon. Stronger color needs a resin chosen for tannins. The lab result, including pH and iron, is what makes that choice.

Testing

For a private well, use a drinking-water laboratory for the health-related sample. Ask which bottles to use and how quickly they need to arrive. Some results change if the sample sits.

A useful first panel for these complaints covers coliform bacteria, nitrate, iron, hardness, pH, and total dissolved solids. Add hydrogen sulfide when you smell rotten eggs, and tannins when the water is tea-colored. A screening test from a treatment company can be a useful look at hardness or iron. The bacteria sample still belongs at a laboratory.

Test again when the color, taste, or smell changes, and after treatment is installed or serviced, so you can see whether the equipment changed the result it was chosen for.

Treatment that follows the test

Iron, hardness, sulfur, and tannins are different jobs. A practical sequence handles iron, sulfur, or tannins first, then softens if the hardness result calls for it. Reverse osmosis on a kitchen tap treats that tap. The rest of the house stays on the main line.

Bring the report when you talk with a company. Ask which result each piece of equipment is there to change, what it leaves unchanged, and what maintenance and follow-up testing look like.

Our team can take a quote request if you want help lining that report up with companies that list the relevant services. A listing is what the business reports. It is separate from independent verification and from an ownership claim.

LISTINGS

Companies that list these services

Each link opens the provider list filtered to a recorded category. Confirm the service, the service area, and the test method with the company. Water testing has its own category. If that list is empty, ask a well or filtration company whether they test, and send bacteria samples to a drinking-water laboratory either way.

• Water testing. Companies that list water testing. Confirm the visit covers the complaint you actually have, and use a laboratory for coliform bacteria.
• Well-water systems. Well-water systems, once a test shows what the well needs.
• Water filtration. Iron, tannin, and sulfur equipment is listed here as filtration or an oxidizing system.
• Water softeners. Softeners for measured hardness, with iron and tannins already accounted for.
