Cotinine in Broward County Florida Water

Unhealthy Levels of Cotinine in the Water Supply of Broward County Florida Homes

Cotinine, a breakdown product of nicotine, can enter the water cycle when tobacco residues reach wastewater and, eventually, drinking water sources. In Broward County — where much of our water comes from the Biscayne Aquifer and moves through municipal treatment — homeowners sometimes see cotinine mentioned as an environmental marker for tobacco exposure. If you’ve spotted the name on a report or want clearer reassurance about the water running from your taps in Fort Lauderdale, Hollywood, Pembroke Pines or nearby neighborhoods, it helps to know how cotinine behaves in water and what treatment steps are effective.

Cotinine usually occurs at very low, dissolved concentrations that don’t change water’s taste, smell, or appearance, so it can be easy to overlook. Because it’s dissolved, cotinine can pass through simple sediment screens that only capture sand, rust, and larger particles; basic pitcher filters may also miss persistent organic molecules. Given Broward County’s hard water and the strain that can place on plumbing and appliances, many local families find a whole-house strategy useful for broadly reducing trace contaminants before they reach fixtures and devices around the home.
