Science you can join

Restoring Florida's canals and coasts takes more than scientists. It takes the people who live, work and fish along them.

Free water quality testing · Marco Island

Free testing at your Marco Island dock

Marco Island's canals have been on Florida's impaired waters list since 2019, and residents have been asking why for just as long. We work with independent university researchers to answer that question with data.

Testing happens right at your dock and takes about 15 minutes. You don't need any equipment or experience. Your reading becomes part of the record for Marco Island's canals.

At your dock · About 15 minutes · Book through December 31

Book your testing visit

Free testing is open to Marco Island residents only.

The results so far

What residents' docks are telling us

Every testing visit adds a point to our Marco Island water quality map. Select any point to see oxygen, temperature and salinity from the surface to the canal floor, and how healthy that water is for fish and marine life.

Canal Science Symposium

Held August 28 at the Marco Island Public Library. Four researchers presented what the data shows about Marco Island's canals: where the nitrogen is coming from, what the monitoring shows, and which options the science supports.

Watch it and judge the evidence for yourself.

Held in collaboration with the University of Florida and the University of South Florida. The Collier County Public Library does not sponsor or endorse this program.
