Lincoln Memorial Reflecting Pool before and after
WLWT • • general
Key Points:
- The Lincoln Memorial Reflecting Pool turned green with algae just days after a $14.2 million renovation funded by the Trump administration, which included painting the pool bottom and resealing seams.
- Algae appeared shortly after the pool was refilled, prompting workers to clear it; the Interior Department explained this as residual algae from dormant supply lines during construction, a normal part of restarting the pool.
- The pool's shallow, slow-moving water and exposure to warm temperatures and sunlight make it naturally prone to algae blooms, especially during summer months.
- Officials stated that nanobubbler technology will be used to maintain the pool and prevent future algae growth, ensuring the pool remains clear for the country’s 250th birthday celebrations.
