One way or another, will the algae infested reflecting pool in DC have clear water on July 4?

The Lincoln Memorial Reflecting Pool, which had turned green with algae after a $14.6 million renovation, was cleared of the bloom ahead of July 4, 2026. Interior Secretary Doug Burgum said on July 3 that the algae was "all gone," describing the pool as "completely clean and clear." The green tint had appeared in June after the Trump administration refilled the pool following work that included repainting its bottom. Researchers identified the bloom as a harmless algae species, the kind expected when nutrient-rich water sits in warm, sunlit conditions. To clear it, crews treated the water with hydrogen peroxide and deployed what officials described as "nanobubble ozone technology" to neutralize the algae and other pathogens. The cleanup was completed in time for Independence Day and the America 250 celebrations on the National Mall. The Predict Six community anticipated the result, with 91 percent forecasting clear water by July 4. The question's "one way or another" phrasing allowed for any method of clearing the pool, a condition the chemical and ozone treatments satisfied.
