How we score a Longwood 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 Longwood.
Need is the wrong word: your Longwood 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.
