Nanobubble tech targets Reflecting Pool, fueling political debate
A $1.7 million ozone nanobubbler project is being used to clear the Lincoln Memorial Reflecting Pool, with temporary units, a permanent pump-house system, and a goal to beat algae before July 4. While officials and researchers say the technology can oxidize algae and keep water clear for days, the effort has drawn scrutiny over a no-bid contract, timing pressures, and the long‑term viability of using the system in a large, outdoor pool, as questions about pipe upkeep and broader renovations remain.
