THANK YOU to all of our volunteers!


Volunteers are the backbone of our program  –  Secchi Dip-In (SDI) couldn’t exist without them and we sincerely appreciate the time, knowledge, and skills each volunteer donates to SDI efforts!


Water bodies around the globe can only realistically remain clean via the sampling and outreach volunteers perform throughout the year.
