Timeline: Lincoln Memorial Reflecting Pool Photos Before and After
Algae returned within days, even after the resurfacing was completed and the pool reopened, officials said.
The Lincoln Memorial Reflecting Pool has turned bright chartreuse green again, despite an administration-led $14.8 million renovation earlier this month aimed at achieving an "American Flag blue" surface.
Structural issues from the pool's construction on unstable mudflats continue causing leaks, while summer heat and the Tidal Basin's algae-prone water have long fueled algal blooms at the landmark.
That project cost taxpayers at least $16.4 million and included a nanobubbling system intended to kill algae, yet the pool now sits hidden under 18 to 30 inches of swamp water dense with algae plumes.
Workers poured hydrogen peroxide into the water yesterday to clear the hue, while Martin stated on June 10 that the green color represents merely "residual algae from the supply lines."
Judy Scott Feldman, president of the National Mall Coalition, criticized the project's aesthetic goals, telling CNN: "It's not supposed to look like you're going to dive in and swim.
Renovation of Reflecting Pool cost $14.2 million, seven times more than expected. But algae remain and celebrations of the 250th anniversary of the United States are approaching
