What to know about Bonita Springs's water
Bonita Springs ranks #182 out of 388 cities in Florida for water quality, placing it mid-range in the state.
Bonita Springs relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff.
Haloacetic acid (HAA5) levels were elevated at 32.5 µg/L in UCMR 4 testing, though below the 60 µg/L EPA limit. Activated carbon filtration can help reduce these disinfection byproducts.
Hexavalent chromium (chromium-6) was detected at 0.12 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration.
The system has seen 10 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
