Fighting for Drinkable, Fishable, Swimmable Water
Thank you for all that you’re doing to improve our water quality and to educate us on changes we ourselves can make to help.
I have come to value the work of the Calusa Waterkeeper and its important voice in our community advocating for cleaner water. Keep up with the good work!
We appreciate all that you do for our community and water quality. Great Job! Thank you, The Jensens.
Thank you Calusa Waterkeeper and John Cassani for all you do to educate the public about the water quality crisis we are facing in SWFL.
Thanks to CWK for relentlessly using science and public outreach to fight for clean water in SW Florida! We all benefit.
I have learned so much as a volunteer Ranger with Calusa Waterkeeper. Excited to continue!
