Lincoln Memorial Reflecting Pool Renovation Experiences Algae and Sealant Issues

2026-06-19

The BareStory

A recent multi-million dollar renovation of the Lincoln Memorial Reflecting Pool in Washington, D.C., has encountered early issues with algae blooms and damage to a newly applied surface sealant. Initiated in April ahead of the nation's 250th anniversary and Fourth of July celebrations, the project involved coating the century-old pool's stone flooring with a waterproof liner.

Shortly after water was pumped back into the reflecting pool, green algae appeared and tears or peeling were observed in the new material. Federal contracts for the repainting exceeded $14 million, with total costs surpassing $16 million when including a newly installed nano-bubble filtration system intended to eliminate algae.

The Department of the Interior stated that the algae outbreak was a normal part of the startup process, attributing it to dormant supply lines. The department later announced that the water had cleared after the new filtration technology successfully killed the growth, noting that personnel are currently vacuuming dead algae from the pool floor.

President Trump, who launched the renovation and selected the new surface color, defended the project by citing his background in building pools. An Interior Department spokesperson praised the work as a permanent fix, contrasting it with costly overhauls under previous administrations. Conversely, critics have accused the administration of altering capital landmarks without congressional approval or adequate public input.

How it may affect me

As a U.S. reader:

• Your federal tax dollars are funding the 16 million dollar reflecting pool renovation, which may either yield long-term savings by acting as a permanent fix or incur additional public costs to repair the initial tearing and peeling of the waterproof liner.

• If you visit the Washington, D.C. landmark in the short term, you may encounter ongoing maintenance efforts, such as personnel vacuuming dead algae from the pool floor, and visible damage to the newly applied surface material.

• During long-term visits, particularly around the nation's upcoming 250th anniversary and Fourth of July celebrations, you will experience a visually altered reflecting pool featuring a new surface color chosen by the executive branch and clearer water maintained by a modernized filtration system.

• You may have fewer opportunities to provide civic input on future alterations to national historical monuments, as this project establishes a precedent for the executive branch to bypass congressional oversight and public comment periods in order to expedite infrastructure timelines.
