The algae blooms in the Reflecting Pool pose aesthetic and environmental challenges, particularly as the site prepares for the 250th anniversary celebrations around July 4th. The green discoloration detracts from the pool's iconic appearance and may require costly and labor-intensive treatments to manage. Additionally, the use of hydrogen peroxide, while less harmful than chlorine, could pose risks to wildlife if not carefully managed. Experts warn that climate change will likely make such issues more common, as rising temperatures and prolonged warm seasons create ideal conditions for algae growth.
