Lake Mary Jane, FL tap water
About 50% of Lake Mary Jane is inside a utility's service area. Homes outside it likely use private wells, which no utility tests.
Disinfectant
Chlorine
Utility water here is treated with chlorine. It slowly gases off from standing water, and any water conditioner removes it. Private wells aren't treated by a utility, so there's no chlorine or chloramine unless a treatment system adds it.
Safety for fish and shrimp
