Algae Rebounds in DC's Reflecting Pool After Renovations
Algae blooms have returned to the Lincoln Memorial Reflecting Pool in Washington, D.C., just after renovations that altered its color; the calm, nutrient-rich waters fed by the Potomac River and warm temperatures create ideal conditions for algae. Officials are temporarily fighting the bloom with hydrogen peroxide and ozone nanobubble technology, but long-term control will require addressing nutrient inputs and the pool’s design.
