Introduction

The iconic Reflecting Pool on the National Mall has long struggled with algae, murky water, and debris. In early July 2026, the Department of the Interior announced a comprehensive plan to restore and maintain the pool’s clarity, building on previous attempts to achieve a blue, sparkling surface.

Plan Overview and Funding

The new initiative calls for a contractor to manage daily cleaning and long‑term upkeep, with a budget exceeding $14 million—far above earlier estimates. The contract, expected to begin in August, includes draining the pool after Independence Day, repairing the lining, and a systematic annual purge of “slick and nasty” sediment that includes leaves, bird and duck droppings.

Advanced Water Treatment

A centerpiece of the effort is a $1.7 million ozone nanobubbler system installed earlier in the year. This high‑tech device injects oxygen‑filled bubbles that break down algae and contaminants, reducing the need for harsh chemicals. The plan also authorizes occasional hydrogen peroxide applications, though the nanobubbler remains the primary, environmentally friendly treatment.

Daily Maintenance Tasks

The selected contractor will manually remove debris, animal waste, and pollen each day, clean filters and skimmers, and pressure‑wash the surrounding concrete and coping stones each month. Any dead animals found will be reported and disposed of safely, protecting both visitors and wildlife.

Safety and Environmental Considerations

The request for bids emphasizes that the accumulated muck must never be allowed to dry, as it poses respiratory hazards when airborne. By keeping the material moist and removing it promptly, the plan safeguards public health and preserves the surrounding ecosystem.

Conclusion

With a robust maintenance schedule, modern ozone technology, and a strong focus on safety, the new Reflecting Pool cleaning plan promises a cleaner, more inviting landmark for Washington, D.C. Residents and tourists can look forward to a brighter, healthier view of this historic space for years to come.
