Reflecting Pool Renovation Sparks Algae Bloom, Paint Peeling, and Political Dispute

Core Event: Renovation and Immediate Issues
$14 million refurbishment of the Lincoln Memorial Reflecting Pool finished June 3, applying a “American flag blue” coating and installing an ozone nanobubbler system. Within days the water turned green with a *Scenedesmus* algae bloom, and sections of the coating began peeling. It was promoted as part of a beautification drive for the 250th-anniversary.
Official Responses and Opposition
President Trump’s Truth Social post blamed “vandalism” and claimed 75 % of the algae problem was solved. The Interior Department said its nanobubbler technology had “effectively eliminated the algae” and called the water “crystal clear.” National Park Service spokesperson noted the system is milder than chlorine and crews are vacuuming dead algae. Governor Tim Walz called the project a “grift” ignoring expert advice. Host Chris Hayes called the pool a “leaky, peeling, algae-infested mess” and said the “crystal-clear” claim was false. The New York Times reported a $1.7 million no-bid contract awarded to an Ohio firm owned by a longtime Trump donor, raising favoritism concerns.
On-the-Ground Observations and Gaps
Park Service crews deployed skimmers and vacuum units to remove algae and paint flakes. Visitors called the water “green, like vomit.” Smithsonian marine-plant specialist Brooks Barrett said the pool’s warm, stagnant conditions are “perfect” for algae growth. The Interior Department’s claim that algae are dead conflicts with these observations of persistent green water. Cost estimates differ sharply between the administration’s $1.5 million figure and the audited $14 million spend. No independent audit of the nanobubbler system’s efficacy has been released.

Future Actions
Cleaning crews will keep vacuuming and applying hydrogen peroxide through the July 4 Independence Day period. The Interior Department will monitor nanobubbler performance and evaluate the blue coating’s durability before further statements.
