Overview
- The pool was refilled after a multimillion‑dollar spring renovation and reopened in early June, but within days the water turned green from algae and large sections of a newly applied blue waterproof coating began peeling.
- National Park Service crews treated the bloom by pouring hydrogen peroxide, vacuuming dead algae and deploying a contracted nanobubbler filtration system while contractors inspected the failing coating.
- The White House has publicly blamed vandalism and alleged a 250–300‑foot gash and chemicals in the water, leading to multiple arrests and citations and a promise of prosecution from the U.S. Attorney for D.C., but officials have not publicly produced corroborating forensic evidence.
- Crews began draining the pool on June 22 to allow immediate repairs after the president met with contractors, even as internal reports and experts cited coating defects and noted that buried 12‑inch circulation pipes were not replaced and were deferred to fall work.
- The project’s rapid, largely no‑bid contracting and rising costs—estimated around $14–16 million—have prompted legal challenges under preservation law and oversight scrutiny that leave the basin vulnerable to repeat failures unless circulation infrastructure is fully fixed.
