The blue coating on the bottom of the Lincoln Memorial reflecting pool is peeling off in large sections just days after a renovation [3].

The failure of the sealant at a primary national landmark raises questions about the quality of the materials used and the oversight of the project's execution.

Reports from June 18 and 19 indicate that chunks of the "American flag blue" paint are floating to the surface of the water [3]. The deterioration has also coincided with the return of algae in the pool [2].

"The 'American flag blue' paint job appears to be falling apart, peeling away from the bottom of the pool," an ABC7 News reporter said [2].

The renovation was carried out under the Trump administration. Estimates for the cost of the project vary between $14.2 million [4] and approximately $15 million [1].

There are conflicting reports regarding the cause of the damage. Some sources indicate that workers dumped hydrogen peroxide into the pool to combat algae, which subsequently dislodged the sealant [1]. Other reports suggest the failure is due to the poor application of the coating during the renovation process [2].

"Blue material peeling off bottom of Reflecting Pool, days after costly renovation," CNN staff said [3].

The pool serves as a central focal point for the National Mall in Washington, D.C. The current state of the liner has left the pool floor uneven, and the water discolored as the blue material separates from the base [4].

“"The 'American flag blue' paint job appears to be falling apart, peeling away from the bottom of the pool."”

The rapid degradation of the reflecting pool's liner suggests a potential failure in either the material specifications or the application process of the sealant. Because the project involved significant public funding—upwards of $14 million—the incident may lead to official inquiries regarding contractor accountability and the durability of the chosen 'American flag blue' coating against standard maintenance chemicals like hydrogen peroxide.
