Overview
- Interior Secretary Doug Burgum told CNN that photographs show deliberate cuts in the new industrial liner and said the administration will use the same no‑bid contractor to fix the damage.
- Officials say nanobubbler ozone units plus vacuuming and peroxide dosing removed the algae and restored clarity to the pool after a brief bloom.
- Observers and internal reports documented floating or peeled sections of the dark blue liner and coating flaws such as bubbles and pinholes that engineers say point to workmanship or material problems.
- Law enforcement has arrested multiple people and a grand jury indicted at least one suspect on destruction‑of‑property charges, while preservation groups have sued under the National Historic Preservation Act.
- Procurement and technical risks remain: the fast‑tracked, no‑bid project grew into the low‑to‑mid tens of millions of dollars, the buried 12‑inch circulation pipes were not fully replaced, and engineers warn those plumbing failures could let algae recur unless addressed this fall.
