The National Park Service employed an innovative method to combat algae in the Lincoln Memorial Reflecting Pool on Tuesday, June 16, 2026, in Washington, D.C. Using hydrogen peroxide and tiny bubbles, crews worked to restore the iconic pool's clarity.
Cleanup Operation Details
The treatment involved applying hydrogen peroxide, a common disinfectant, along with microbubbles to break down and remove algae growth. This approach is considered environmentally friendly compared to harsh chemicals, as hydrogen peroxide decomposes into water and oxygen.
Why This Method?
Algae blooms have been a recurring issue in the Reflecting Pool, often caused by warm temperatures and nutrient runoff. The National Park Service chose this technique to minimize ecological impact while effectively clearing the water.
The Lincoln Memorial Reflecting Pool, a popular tourist destination, spans over 2,000 feet and is part of the National Mall. Regular maintenance is required to preserve its appearance for visitors.
