Is Orlando, FL Tap Water Safe to Drink?
Yes, Orlando tap water is safe to drink. No contaminants exceed health guidelines. However, Orlando has very hard water at 200 PPM, which will cause scale buildup in plumbing and appliances over time. A water softener is worth considering.

How Orlando Compares
Orlando's water is 45% harder than the national average of 138 PPM. It ranks #308 out of 1000 cities in our database (harder than 69% of US cities we track). Within Florida, it ranks #58 of 64 cities (15% below the state average of 236 PPM). Among major US cities (500k+), Orlando ranks #29 of 100 for hardness. At this hardness level, water heaters run an estimated 37% less efficiently due to scale insulation, and major water-using appliances typically last 3 years less than the national average lifespan.
What Orlando's Water Means for Your Home
Hardness: 200 PPM - Treatment Recommended
Orlando has some seriously hard water. At 200 PPM (11.7 grains per gallon), your tap is loaded with dissolved calcium and magnesium picked up from underground limestone and dolomite formations. Here's the thing: it's perfectly safe to drink. The minerals won't hurt you. But they will hurt your wallet. That adds up. Hard water at 200 PPM increases household costs through scale-coated water heaters that use more energy, extra soap and detergent, and appliances that wear out faster. Most Orlando homeowners don't realize it until the plumber shows up. That's 15% softer than the Florida average.
Contaminants & Safety
Disinfection byproducts are the notable finding here. Orlando's water has TTHMs at 53.4 ppb and HAA5 at 23.8 ppb — both within legal limits, but the EWG health guidelines are far stricter. These byproducts form when chlorine reacts with organic matter during treatment. A whole-house activated carbon filter reduces both chlorine and its byproducts. Want the full picture? Request your utility's annual Consumer Confidence Report.
What's in the Treatment Process
Even though Orlando draws from groundwater, the treatment process still generates disinfection byproducts: TTHMs at 53.4 ppb and HAA5 at 23.8 ppb. Groundwater typically needs less treatment than surface water, but when organic compounds are present in the aquifer, chlorination creates the same byproducts. All levels are within legal limits, though above the stricter EWG health guidelines.
Chromium-6 is naturally present in Orlando's aquifer geology at 0.0456 ppb — 2.3x the EWG health guideline. There's no federal legal limit for chromium-6 specifically (only total chromium), which is why EWG tracks it separately. All measurements are within federal legal limits. The EWG guidelines represent a more conservative, health-based standard.
How Hard Water Affects Your Home
At 200 PPM, untreated hard water has measurable effects on household costs and appliance life:
- Water heater inefficiency: Scale insulation forces the heater to work harder (DOE estimates up to 22% more energy for heavily scaled units)
- Soap and detergent: Hard water reduces lathering, requiring significantly more product
- Appliance replacement: Water heaters, dishwashers, and washing machines fail 2-4 years earlier due to scale buildup
- Plumbing maintenance: Scale buildup in pipes reduces flow and requires more frequent service
Note: Impact varies by household size, water usage, and local energy costs. A home water test provides the most accurate assessment for your specific situation.

Our Top Picks for Orlando (200 PPM)
Hard water at 200 PPM causes scale buildup, increased energy use, and premature appliance failure. A softener protects your plumbing and appliances.
Quick Fix for Chlorine: Shower Filter
At 1.4 mg/L chlorine, many Orlando residents notice dry skin, brittle hair, and that "pool smell" in the shower. A shower filter installs in 5 minutes, no tools needed.
How to Test Your Water in Orlando
With 200 PPM hardness, a quick test strip confirms whether your specific tap matches Orlando's average before you invest in a softener. Hardness can vary within the same system.

About Orlando's Water Supply
Water Utility: OUC
Water Source: Floridian Aquifer (Groundwater)
Population Served: 536,466
Hardness: 200 PPM (11.7 grains per gallon)
Orlando draws its drinking water from groundwater sources — Floridian Aquifer. Groundwater typically requires less treatment than surface water because the earth acts as a natural filter. The tradeoff: dissolved minerals from underground rock formations, which is why hardness is elevated here. Calcium and magnesium dissolve into the water as it moves through limestone and dolomite. The system serves 536,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request OUC's Consumer Confidence Report (CCR) or test your own tap.

Water Softener Sizing for Orlando
At 200 PPM (11.7 GPG), here is how to size a softener for your Orlando home. Multiply hardness in GPG (11.7) by daily water usage (roughly 50 gallons per person). A family of four uses about 200 gallons/day: 11.7 GPG × 200 gal = 2340 grains/day. Over a 7-day regeneration cycle, that is 16,380 grains - a 32,000-grain softener is the right fit for most Orlando households.
