Port St. Lucie Utilities covers 224,485 people at 5 of 10 above guideline, while Fort Pierce Utilities Authority's 58,000 customers see 8 of 18. Across 19 reported systems and 331,682 residents, the worst system in the county reaches 9 — and it is the Fort Pierce side of the county that carries most of that weight.
What this does and does not mean
EWG's health guidelines are stricter than federal EPA limits, so water that exceeds them is usually still legal to serve. The dataset reports how many contaminants were detected above guideline, not which ones — the only way to know what is in the water at your tap is to test it there.
