Overview
- The Trump administration carried out a fast, no‑bid renovation of the Reflecting Pool in June that used a darker coating and unproven “nanobubbler” devices to meet a July 4 target.
- Within days of refilling, crews and visitors documented bright green algae, bubbling and peeling of the new coating, and contractors logged durability problems with the sealant.
- Park officials reported deliberate cuts to a protective liner and made multiple arrests for alleged vandalism, but investigators have not publicly resolved whether damage or construction failures explain the defects.
- Reporters identified RHINO 405 epoxy among the lining materials and cited OSHA safety data that flag it as toxic to aquatic life; several dead ducks have been found near the pool, prompting environmental concern and calls for investigation.
- The National Park Service says it will drain the basin after July 4 for warranty repairs while preservation lawsuits and congressional oversight letters press for answers about procurement, quality control and remaining century‑old circulation pipes that were not fully replaced.
