Martin County ranks 24th of 67 at a 5.6 average, 0.8 above the statewide median — but the county's spread is the real story. Martin County Utilities, based in Jensen Beach, serves 104,105 people including much of Palm City at 4 of 12 above guideline, while Stuart's own plant (16,841 served) reports 9 of 21 and South Martin Regional Utilities in Hobe Sound reports 10 of 24. Across all 15 reported systems the county's worst reaches 13 — and whether you are in Stuart, Palm City, Jensen Beach or Hobe Sound decides which of those numbers is yours.
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.
