Rosser has abandoned his dream home on the tony island, taped ominous "Danger: Poison Gas" signs to his front door, and filed a civil lawsuit against the city. Despite the suit and the violation letter from the Department of Environmental Resources Management, Rosser says, Key Biscayne officials have ignored his neighbors' complaints and done nada.
Rosser and his wife, Virginia, now live with friends and struggle daily with headaches, coughs, and sinus infections.
"We've been poisoned," he says. "I hoped the city would admit what they've done and fix the problem, but they don't seem interested in that."
Rosser bought his home, a modest one-story ranch amid the island's gleaming mansions, for $130,000 in 1984 after retiring from Eastern Airlines. The place is now worth $1.2 million — or at least it was until Key Biscayne put a sewage plant next to his back yard.
After construction began in January 2008, Rosser and his neighbors noticed a horrific odor. By the time the plant was finished in October, Rosser couldn't go out in his back yard without gagging.
Says neighbor Enrique Bahamon: "It smelled so bad in our front yard, it came right into our living room."
Late that fall, Rosser and his wife began getting ill regularly. He visited several doctors but didn't stumble on the cause until this past spring: hydrogen sulfide poisoning. The gas behind the sewage's potent smell can wrack the brain and nervous system if it's constantly inhaled.
The Rossers fled their home in May and filed a suit against the city and Metro Equipment Services, the contractor who built the plant.
In June, county environmental regulators sent Key Biscayne officials a letter. The plant, they said, was built without proper permits and was emitting too much hydrogen sulfide. Two days later, Key Biscayne Village Manager Chip Iglesias sent residents a letter laying responsibility on Miami-Dade Water and Sewer.
Today, the plant — a collection of metal boxes and a sewer grate — still churns next to Rosser's picket fence. Conchita Alvarez, Key Biscayne's city clerk, says she cannot comment about an ongoing suit. Water and Sewer officials also declined to comment.
Neighbors say the odor has lessened recently, but they worry whether Rosser's symptoms mean their own families have been poisoned.
"We all get headaches," Bahamon says. "We just hope we don't end up like John."
