Lake George Water Quality Advocates challenging the application of the chemical ProcellaCor into Lake George spring 2022. The chemical was applied in summer 2023 and in summer 2024 testing was done and it was found that there were longer lasting negative impacts than expected.

This page is dedicated to Lake George Water Quality advocate and activist Al Rider, Hague, pictured above who died in summer 2024.

MILFOIL PROCELLACOR ISSUE

ProcellaCOR and the LGA
The LGA monitored the results of applying ProcellaCOR in Blairs and Jilleffe-Knight Bays. It examined the water, sediment and plants. ProcellaCor killed milfoil in both bays but it spread beyond the treatment areas. Additionally, ProcellaCOR degradants were deposited in the lakebed sediment. It also adhered to native plants as well as milfoil. There was short-term decrease in productivity due to reduced photosynthesis as a result of the large plant die-off. There was also a short-term drop in dissolved oxygen which recovered after three weeks.  The LGA intends to collaborate with the LGPC on a long-term invasive species management plan.
