Lake Mary, FL water quality
Lake Mary draws its water from the Floridan Aquifer via City of Lake Mary. Hardness runs from moderate to very high citywide, and disinfection byproducts along with hardness scale are the most common resident complaints.

How we score a Lake Mary neighborhood
No agency publishes testing per subdivision — it is published per public water system. So the score is a documented model, not a measurement:
- 1Start from the serving utility's own published baseline (hardness plus disinfection-byproduct load from its most recent Consumer Confidence Report).
- 2Add for plumbing era: +8 for pre-1960 housing stock, +4 for 1960s-80s, +2 for 1990s-2000s, +0 for 2010 and newer.
- 3Add for service-zone position: +6 where the subdivision sits at the end of long distribution mains (newer master-planned build-outs), +3 for the oldest downtown mains.
- 4Add for local sources: +12 private or community well, +9 airport/GOAA PFAS influence area, +7 industrial adjacency, +3 golf-corridor irrigation, +2 lakefront shallow-well and iron staining.
- 5Clamp to 30-95, then map to low / moderate / high. Wells get chlorine scored near zero — nothing is disinfecting that water at all.

Straight answers
Before you call anyone in Lake Mary.
Need is the wrong word: your Lake Mary utility delivers water that meets every enforceable EPA limit. Filtration is about the things those limits don't cover — hardness that scales your fixtures and water heater, chlorine taste and smell, and disinfection byproducts that sit above the stricter (non-enforceable) EWG health guideline. Legal water and water you enjoy drinking aren't the same standard.
