Problem 1: Hard Water
Symptoms: Scale buildup on fixtures, white deposits on shower doors, stiff/dull laundry, soap scum in tubs and sinks, dry skin after showering, reduced water heater efficiency, higher utility bills.
Cause: Calcium and magnesium dissolved from limestone formations in the Floridan Aquifer. Orlando well water typically has a hardness of 10-25 grains per gallon (GPG), classified as hard to very hard.
Solution: Ion-exchange water softener. A water softener removes calcium and magnesium ions and replaces them with sodium or potassium ions. For Orlando's typical hardness levels, a properly sized residential water softener costs $1,500-3,000 installed. Annual maintenance costs $200-400 (salt and inspection).
DIY vs professional: Water softener installation requires plumbing expertise and understanding of local codes. Professional installation is strongly recommended to ensure proper sizing, correct plumbing connections, and compliance with drainage requirements.
Problem 2: Iron Contamination
Symptoms: Orange-brown staining on fixtures and laundry, metallic taste, reddish water, sediment in glass, staining on white porcelain, metallic odor.
Cause: Naturally occurring iron in the Floridan Aquifer. Orlando well water typically contains 0.3-5 ppm of iron, with some wells containing even higher levels. Iron exists in two forms: ferrous iron (dissolved, clear water that turns orange when exposed to air) and ferric iron (particulate, causes reddish-brown cloudy water).
Solution: Air injection oxidation system or manganese greensand filter. Air injection introduces oxygen into the water to convert dissolved iron into solid particles that are then filtered out. Manganese greensand uses a catalytic coating to oxidize and filter iron. Costs: $1,500-3,500 installed.
DIY vs professional: Iron filter installation requires plumbing work and understanding of the oxidation process. Professional installation is recommended to ensure proper system sizing and operation.
Problem 3: Bacterial Contamination
Symptoms: Cloudy water, unusual odor, gastrointestinal illness in family members, positive bacteria test results. Note: Many bacterial infections have no visible symptoms.
Cause: Surface water intrusion through cracks in the well casing, compromised well seal, or flooding. Bacteria can also grow inside your home's plumbing system if water stagnates for extended periods.
Solution: UV (ultraviolet) disinfection system. UV light kills bacteria, viruses, and protozoa without adding chemicals or altering water taste. For existing bacterial contamination, shock chlorination followed by UV installation. Costs: $300-800 for UV system, $200-500 for shock chlorination.
DIY vs professional: UV system installation is straightforward but requires proper positioning and electrical connection. Shock chlorination should be performed by a licensed well contractor to ensure thorough disinfection.
Problem 4: Hydrogen Sulfide (Rotten Egg Smell)
Symptoms: Rotten egg odor in water, especially when hot water is used, black staining on fixtures and laundry, metallic taste.
Cause: Hydrogen sulfide gas produced by sulfate-reducing bacteria in the aquifer or within the well itself. Common in Orlando wells that draw from deeper aquifer zones.
Solution: Air injection oxidation system or activated carbon filter. Air injection oxidizes hydrogen sulfide to elemental sulfur, which is then filtered out. Granular activated carbon (GAC) adsorbs hydrogen sulfide. Costs: $1,000-2,500 installed.
Problem 5: High Total Dissolved Solids (TDS)
Symptoms: Salty or bitter taste, white scale deposits on fixtures, poor-tasting ice, mineral buildup in coffee makers and kettles.
Cause: High mineral content from the limestone aquifer. Orlando well water TDS typically ranges from 150-800 ppm, with some wells exceeding 1,000 ppm.
Solution: Reverse osmosis (RO) system for drinking water. RO removes 95-99% of dissolved solids. For whole-house TDS reduction, distillation is effective but expensive. Costs: $800-1,500 for under-sink RO system.
Problem 6: Low pH (Acidic Water)
Symptoms: Blue-green staining on copper pipes, pinhole leaks in pipes, metallic taste, corroded fixtures, cloudy water.
Cause: Naturally acidic conditions in certain aquifer zones. Orlando well water pH typically ranges from 6.5-8.0, but some wells fall below 6.5 (acidic).
Solution: Neutralizing filter (calcite or magnesium oxide media). The filter raises pH by dissolving alkaline media into the water. Costs: $800-1,500 installed.
Problem 7: Arsenic and Heavy Metals
Symptoms: No visible symptoms. Testing required. Chronic exposure causes skin lesions, cancer, cardiovascular disease, and neurological effects.
Cause: Naturally occurring arsenic in the Floridan Aquifer, agricultural runoff, or industrial contamination. EPA MCL is 10 ppb.
Solution: Reverse osmosis or activated alumina filter. RO removes 90-95% of arsenic. Costs: $800-1,500 for RO system.
Problem 8: Cloudy or Discolored Water
Symptoms: White, brown, or yellow water, sediment in glasses, staining on fixtures and laundry.
Cause: Sediment (sand, silt, rust) from the aquifer, iron oxidation, or bacterial growth. Air bubbles cause temporary cloudiness that clears within minutes.
Solution: Sediment pre-filter (5-micron or 1-micron). For persistent discoloration, add iron filter or carbon filter. Costs: $200-500 installed for sediment filter.
Problem 9: Low Water Pressure
Symptoms: Weak flow from faucets and shower heads, long fill times for bathtubs and appliances.
Cause: Clogged filters, failing well pump, mineral buildup in pipes, or undersized plumbing. Well water systems with clogged sediment filters are the most common cause of low pressure.
Solution: Replace sediment filters, clean or replace shower head aerators, inspect and service well pump. Professional pump inspection costs $200-400.
Problem 10: Well Water Taste Issues
Symptoms: Metallic, sulfurous, or chemical taste, unpleasant aftertaste, family members complain about water taste.
Cause: Iron, manganese, hydrogen sulfide, chloramine (if connected to municipal), or high TDS. Taste issues are subjective but are among the most common complaints from well owners.
Solution: Granular activated carbon (GAC) filter. GAC effectively removes taste and odor compounds. For drinking water, an under-sink carbon filter or RO system provides excellent taste improvement. Costs: $150-1,500 depending on system type.
Frequently Asked Questions
What is the most common well water problem in Orlando?
Hard water is by far the most common well water problem in Orlando. The Floridan Aquifer naturally contains high levels of calcium and magnesium, giving Orlando well water a hardness of 10-25 GPG. The second most common problem is iron contamination, present in most Orlando wells at varying concentrations. A water softener and iron filter address both issues.
Can I fix all well water problems with one system?
No single system addresses all well water problems. A complete treatment system typically includes multiple stages: sediment filter for particles, water softener for hardness, iron filter for iron, UV disinfection for bacteria, and carbon filter for taste/odor. Work with a treatment specialist to design a system that addresses your specific contaminants.
How much does it cost to fix well water problems?
For most Orlando well water problems, the total installed cost of treatment systems ranges from $3,000-8,000 for a complete system. Specific costs: water softener $1,500-3,000, iron filter $1,500-3,500, UV disinfection $300-800, carbon filter $500-1,500, RO system $800-1,500. Annual maintenance costs $200-400.
Does well water ever get better over time?
Well water quality can change over time due to seasonal variations, aquifer depletion, nearby construction, or changes in land use. Water quality testing every 3-5 years helps you track changes and adjust your treatment system as needed. If water quality deteriorates, you may need to add or upgrade treatment stages.
What is the best treatment for Orlando well water?
The best treatment for Orlando well water is a combination system: sediment filter + water softener + iron filter + UV disinfection + carbon filter. This addresses the four most universal well water challenges in Orlando: suspended particles, hardness, iron, and bacteria. Additional treatment (RO, neutralizer) may be needed based on specific test results.
When should I call a professional for well water issues?
Call a licensed well contractor if you detect bacteria in your water, notice a crack in your well casing, observe flooding around your wellhead, or experience a sudden drop in water flow or pressure. Call a water treatment specialist if your water consistently stains fixtures, has a strong odor that filters cannot resolve, or if you need help interpreting water quality test results and designing a treatment system. For any health-related water concerns, consult a professional immediately rather than attempting DIY solutions.
Can a single system fix all my well water problems?
No single system addresses all well water problems. A complete treatment system typically includes multiple stages: sediment filter for particles, water softener for hardness, iron filter for iron, UV disinfection for bacteria, and carbon filter for taste/odor. Work with a treatment specialist to design a system that addresses your specific contaminants.
Bottom line: Orlando well water commonly has hardness, iron, and bacterial contamination — and virtually every problem has a proven treatment solution. The key is identifying your specific problems through comprehensive water testing ($250-400 for a 50+ parameter lab test) and then designing a treatment system that addresses your actual contaminants.
