The contaminants furthest above health goals in Fort Myers tap water are Arsenic, Total trihalomethanes (TTHM) and Haloacetic acids (HAA9).

What these contaminants are

  • Arsenic: A naturally occurring metal. Long-term exposure is linked to skin, bladder and lung cancer.
  • Total trihalomethanes (TTHM): Disinfection byproducts that form when chlorine reacts with organic matter. Long-term exposure is linked to bladder cancer and liver and kidney effects.

About this data

Results come from testing and annual water quality reports that utilities file with the EPA and the Florida Department of Environmental Protection, compiled in our free water check. Health goals are the stricter of EPA health goals or California public health goals; legal limits are EPA maximum contaminant levels or action levels. Water quality can change between the treatment plant and your home, so these figures are a guide, not a test of your own tap.
