The Pinto Lake Restoration project will treat internal nutrient loadings that drive cyanobacteria blooms using environmentally safe and proven technologies including polymers/coagulants such as aluminum sulfate or similar. Nutrient loading data will be used to determine the type and amount of polymer/coagulant for in-lake treatment. This data will be obtained from sampling of lake sediments and runoff in the tributary creeks. Polymer/coagulant will be applied by purpose-built barge that uses a GPS-linked computer system for boat guidance and integrated, real-time polymer/coagulant dosing control. The project timeline will be approximately 6 months.
