The Trump administration has deployed a Brookfield, Ohio-based company to lead an effort to clean the Lincoln Memorial Reflecting Pool using a $1.7 million "ozone nanobubbler" system that injects 500 million microscopic bubbles per teaspoon of water.
The technology works by injecting ozone-enriched oxygen into the pool's 6.5 million gallons of water, oxidizing algae, bacteria and other chemicals to achieve clarity. The administration has characterized the technology as "state of the art."
The company is one of only a few in the country with this type of equipment. The technology itself is five years old but has never been formally used or researched on a pool.
What the Left Is Saying
Progressive critics have questioned whether untested technology should be deployed at such a prominent national monument without more established methods being attempted first. Some environmental policy advocates have noted that the Reflecting Pool's recurring water quality issues stem from deeper systemic problems with the National Mall's aging infrastructure, and question whether technological fixes address symptoms rather than causes.
What the Right Is Saying
Supporters of the administration have highlighted the innovation as an example of leveraging cutting-edge American technology to solve long-standing public space challenges. The White House has pointed to the project as a demonstration of efficient federal problem-solving that bypasses bureaucratic delays associated with traditional renovation approaches.
What the Numbers Show
The Lincoln Memorial Reflecting Pool holds approximately 6.5 million gallons of water and has historically required extensive chemical treatment or draining for cleaning. The ozone nanobubbler technology being deployed costs $1.7 million. The system generates 500 million microscopic bubbles per teaspoon of water injected, with the goal of oxidizing organic material including algae, bacteria and dissolved chemicals.
The Bottom Line
The project represents a high-profile test case for whether emerging technology can effectively address long-standing infrastructure challenges at federally managed monuments. Success or failure will likely inform future debates about how to maintain National Mall facilities.
