Florida Well Water Specialists
Southwest Florida well water presents some of the most complex treatment challenges in the state. We have been designing multi-stage well water systems for Sarasota and Manatee County since 2014.
The Florida Well Water Challenge
Southwest Florida sits above the Floridan Aquifer System — one of the most productive freshwater aquifers in the world, but also one of the most mineralogically active. As groundwater moves through ancient limestone formations, it dissolves calcium carbonate (creating extreme hardness), picks up iron and manganese from geological deposits, and in deeper anaerobic zones, creates hydrogen sulfide from sulfate-reducing bacterial activity.
The result is well water that frequently combines very high hardness (20–35 gpg is common), elevated iron (2–8 mg/L is not unusual), detectable hydrogen sulfide, and pH between 6.5–7.5 — often requiring a treatment sequence of 4–6 stages to address all issues effectively. Treating only one or two symptoms while leaving others unaddressed is a common and expensive mistake.
We have designed and installed hundreds of well water treatment systems across Sarasota and Manatee Counties. We know this water, and we know the sequences that work.
Annual Testing Recommended
The Florida Department of Health recommends testing private well water annually for bacteria and nitrates. Many well owners haven't tested in years — or ever. Our free water test covers the most important parameters.
We test for all critical well water parameters in-home, plus lab analysis for bacteria and nitrates.
Well water often requires 4–6 treatment stages in the correct sequence. We engineer the right order.
We evaluate your submersible pump, pressure tank, and pressure switch as part of every well water consultation.
Well water chemistry can change seasonally. We recommend annual re-testing to catch changes early.
Florida Well Water Issues
Most Florida well water systems address multiple simultaneous issues.
Florida well water often contains dissolved (clear-water) iron between 0.5–8 mg/L from the Floridan Aquifer. Above 0.3 mg/L causes rust stains. Above 1.0 mg/L causes metallic taste. Requires oxidation filtration.
Rotten egg odor from sulfate-reducing bacteria in anaerobic zones of Florida aquifers. Common in deep wells. Ranges from trace odor to 2+ ppm. Treated with aeration, oxidation, or carbon filtration.
Well water in Sarasota and Manatee Counties typically ranges from 15–30+ gpg — classified as very hard. The Floridan Aquifer runs through limestone, dissolving calcium carbonate constantly.
Florida's warm climate and shallow water tables create conditions favorable for bacterial growth. Well caps, casings, and annual flooding events are all contamination vectors. Regular testing and UV protection are critical.
Many Florida wells — especially shallow wells in areas with organic-rich soils — have pH below 6.5. Acidic water corrodes copper pipes, causes blue-green stains, and creates metallic taste.
Organic tannins from decaying vegetation create a tea-colored appearance in shallow Florida wells near wetlands, rivers, and organic soils. Treated with anion exchange media.
Often co-occurring with iron, manganese causes black or brown staining and is associated with neurological effects at elevated concentrations. Treated with oxidation and specialized filtration media.
Agricultural runoff and septic system leachate can introduce nitrates into shallow wells. Concentrations above 10 mg/L are a health concern — particularly for infants and pregnant women.
Treatment Architecture
Treatment stages are applied in a specific sequence — order matters significantly for effectiveness.
First line of defense — protects all downstream equipment from sand, grit, and particulate that well pumps can introduce.
For iron and hydrogen sulfide — converts dissolved contaminants to filterable particles through oxidation (air injection, ozone, or chlorination) before the filter media.
Specialized catalytic carbon or manganese greensand media that captures oxidized iron, manganese, and hydrogen sulfide at the particulate stage.
Calcite or corosex media raises pH from acidic range (below 6.5) to neutral (7.0–7.5), protecting plumbing and fixtures from corrosion damage.
Ion exchange softener for hardness reduction — removes calcium and magnesium, eliminates scale buildup, and dramatically improves soap efficiency.
Final disinfection barrier — 99.99% effective against bacteria, viruses, and protozoa. Essential for any well water system where bacterial risk exists.
Note: Not every well requires all six stages. System design is based on your specific water test results. Many wells need only 2–4 stages — we never add unnecessary components.
“We moved to Parrish from city water in Sarasota and had no idea what to expect from a private well. Convenient Water came out, tested everything, and walked us through exactly what our water contained and why. The system they designed addressed three issues we didn't even know we had. The water is now incredible.”

“The sulfur smell in our well water was so bad guests thought something was wrong with the house. After Convenient Water installed a two-stage iron and sulfur filter, the smell was completely gone on day one. I wish we had called them years earlier.”

Well Water FAQs
The Florida Department of Health recommends testing private well water annually for bacteria and nitrates, and every 2–3 years for a comprehensive panel. Additionally, you should test after any flood event, after work on the well or plumbing, if there is a change in taste, odor, or color, if a new baby is in the home, or if a household member develops gastrointestinal illness. Our free water testing service covers 12 parameters in-home and includes bacterial lab analysis.
Hydrogen sulfide (H2S) at low concentrations (under 0.5 ppm) is generally considered a nuisance rather than a health hazard in drinking water. However, it also indicates the presence of sulfate-reducing bacteria, which can create biofilm in your plumbing and potentially harbor other pathogens. High concentrations (above 1 ppm) can cause nausea in sensitive individuals. We recommend testing your water to measure the actual concentration and also check for bacterial contamination, which is common in sulfur-odor wells.
Potentially yes — and this is what makes well water particularly important to test. Bacterial contamination (including E. coli and Giardia), nitrates, arsenic, and emerging contaminants like PFAS are all odorless and colorless in typical concentrations. The only way to know your well is safe is to test it. Our free water test covers the parameters most relevant to Southwest Florida well water.
Well water treatment system sizing depends on: (1) your specific water chemistry — contaminant types and concentrations from your water test; (2) your household peak flow rate — typically 1.5–2 gallons per minute (GPM) per bathroom; (3) your pressure tank configuration and pump output; and (4) your daily water usage volume for ion exchange and backwash calculations. We perform all of these measurements during the site assessment and use them to select and size every component in the system.
A properly designed well water treatment system should have minimal impact on water pressure — typically 5–15 PSI pressure drop across the full treatment train under normal flow. However, undersized media tanks, undersized filter housings, or clogged pre-filters can cause significant pressure drop. This is why proper sizing matters: we design systems with flow rates that accommodate your peak demand, and we include pressure testing as part of every installation.
