Calusa Waterkeeper will host a public water summit from 5:30-9 p.m. on June 24 at Broadway Palm Dinner Theatre.

The event, called “Public Health Alert – Florida Water,” will include a screening of the documentary Toxic Puzzle, narrated by Harrison Ford.

An expert panel, including two scientists featured in the documentary, will discuss why harmful algal blooms have become a public health concern, where to find key information as the threat evolves, and what Southwest Florida residents can do to help safeguard themselves and their families while fighting for change. A question-and-answer session with the experts will follow the panel presentation.

The Southwest Florida Community Foundation is funding the program through a grant. A second public forum is set for Aug. 5.

Tickets, which include a buffet dinner, are $20, with proceeds benefiting Calusa Waterkeeper’s scientific research and educational outreach efforts. Tickets are available at Sponsorship opportunities are also available.
