Water Quality and Contaminants

Florida's diverse aquatic resources are threatened by many human activities that can affect water quality and fish habitat and increase the likelihood of contaminants accumulating in water and fish. Project staff members monitor changes in water quality and levels of contaminants, including mercury in fish, in Florida's fresh and marine waters.
