The Florida Power and Light Co. and other state utility companies have been accused of contaminating groundwater in the region for decades.
The state has not yet formally acknowledged the contamination, but it has said it has made progress in cleaning up the region’s air, water and soil.
A group of environmental and other groups has filed a lawsuit against the state for the contamination.
A Florida judge is expected to rule soon on the lawsuit.
The Environmental Protection Agency has also been implicated in the contamination of groundwater.
A 2015 investigation found that two water wells were contaminated with a substance that is a byproduct of the oil and gas industry.
It also found that the EPA failed to monitor the groundwater before it was contaminated, and that the company continued to pollute the water even after the EPA had declared the contamination safe.
In addition, a lawsuit filed in federal court by the environmental group Clean Water Action accuses the EPA of ignoring the pollution in Florida, and of failing to protect Florida’s aquifers.
The EPA has not commented on the case.
The EPA did not respond to a request for comment.
