SARASOTA COUNTY — Warm Mineral Springs resident Inna Udall asked Sarasota County commissioners Tuesday about the environmental impacts at the spa that could potentially harm visitors.

“After hearing William Delp (a diver who in 2010 observed rolling plastic sheets at the bottom of the springs — placed there in 1992 — that could now be polluting the spa through phthalate particles, a chemical commonly added to make plastics flexible in the water. He said the phthalate also disrupts the flow of water and mineral content) speak at the North Port City Commission meeting (on Nov. 26), I’m concerned about the quality of the water and the pollutants in the lake,” she said. “I understand you all want this for economic development and that’s excellent. I am concerned that there might be toxins in the water that could cause cancer and other ailments. I just want to know if it’s safe and if it has a clean bill of health.”
