Rips Appear in Reflecting Pool's New Sealant, Chosen by Trump, After Algae Turn Water Green

TL;DR

  • The Lincoln Memorial Reflecting Pool's recent renovations encountered issues with algae and rips in the new sealant.
  • President Trump personally selected the sealant's "American Flag Blue" color and oversaw the project, which had federal contracts valued at over $14 million.
  • An algae bloom turned the pool's water green shortly after it was refilled, which the Department of the Interior attributed to residual algae from dormant supply lines.
  • Workers treated the algae with hydrogen peroxide and nanobubbles, and the water was later reported as clear.
  • A tear was subsequently discovered in the pool's sealant.
  • This is the second major overhaul of the Reflecting Pool in less than 20 years, following a project during the Obama administration.
  • Critics have accused Trump of self-aggrandizing projects and making changes without proper congressional or public input.
