Place: Bay Pointe Marina, C-43 canal/Caloosahatchee River, Florida, USA
Date: 28 May ,1 June & 4 June, 2021
Background:
This remediation project objective was to handle, contain, and eliminate ongoing cyanobacterial blooms in residential areas that span along a 48-mile length segment of the C-43 Canal/Caloosahatchee River, from the S-77 (Moore Haven Lock & Dam) to Fort Myers, in order to minimize their impact on health and quality of life
BlueGreen’s technical experts together with Modica and Associates (Modica), licensed applicators, have assessed the C-43 Canal and its adjacent waterways in order to establish a proper mitigation protocol for the treatment regimen designed to target cyanobacterial outbreaks in progress, as well as to mitigate the developing conditions that may lead to such outbreaks in residential canals. Treatment was conducted with the Lake Guard® Oxy product, approved by the U.S. EPA, certified by the NSF/ANSI/CAN-60 for treatment in drinking water, and registered with the Florida Department of Agriculture and Consumer Services.

Treatment details
Microcystins / nodularins (top panel) and saxitoxins (bottom panel) (in ng/mL, ppb) found in site #1 on May 28th and June 2nd, 2021.
Conclusions: In total, BlueGreen/ Modica inspected, treated and maintained residential canals over a 48-mile long river segment, conducting a total amount of 112 treatments/ retreatments at 56 different sites.
The treatments provided immediate relief to the residents that suffered from heavy blooms near their homes and a strong foul odor that accompanied the blooms.
While saxitoxins values exhibit no clear trend, a general trend of decrease in toxin levels is demonstrated for microcystins / nodularins.
