The National Park Service is actively working to remove algae from the Lincoln Memorial Reflecting Pool, which has recently turned green following its renovation completion. The Department of Interior is utilizing hydrogen peroxide and nanobubble ozone technology to combat the algae blooms that emerged just days after the pool’s refurbishment was finalized. A spokesperson indicated that the algae growth was linked to reactivated supply lines, and workers were observed applying treatments as well as scraping algae from the bottom of the pool. The hydrogen peroxide is claimed to be environmentally safe, while the nanobubble technology helps kill algae and other contaminants. Despite the renovation, some visitors expressed skepticism about the effectiveness of the efforts, noting the pool’s persistent algae issues.
Why It Matters
The Lincoln Memorial Reflecting Pool, constructed in the 1920s, has faced ongoing challenges with algae proliferation, particularly during warm weather. Previous efforts to address this issue include a $35 million renovation by the Obama administration in 2012, which aimed to improve the pool’s filtration system. The current renovation, originally intended as a quick fix, escalated to nearly $15 million, highlighting the complexities involved in maintaining this iconic landmark. The ongoing algae problems underscore the need for sustainable solutions to preserve the Reflecting Pool’s aesthetics and historical significance, particularly as the nation approaches its 250th anniversary.
