Lincoln Memorial Reflecting Pool Faces Algae Bloom, Peeling Paint and Vandalism After $16 Million Renovation

A $14‑$16 million renovation of the Lincoln Memorial Reflecting Pool, ordered by President Donald Trump and completed in June 2026, quickly ran into problems. Within days, a dense algae bloom turned the water a murky green, prompting the National Park Service to apply hydrogen peroxide and advanced nanobubble technology. At the same time, sections of the new blue coating began to peel away, leaving exposed concrete and floating fragments.

President Trump blamed “vandalism” and cited graffiti reading “86 47” on the National Mall, saying law‑enforcement investigations were under way. Contractors Atlantic Industrial Coatings and Green Water Solutions were awarded no‑bid contracts totaling roughly $14.7 million for coating and $1.7 million for water‑treatment work, pushing the total cost above $16 million. Experts noted that coating failures can result from surface preparation, contamination, or environmental exposure, and that algae blooms are a recurring issue in the shallow, nutrient‑rich basin. Health officials warned that cyanobacterial toxins could pose skin and respiratory risks, urging the public to avoid contact. The pool’s ongoing deterioration has become a focal point for political criticism and media coverage.
