Algal blooms have resurfaced in the Reflecting Pool on the National Mall, striking the iconic stretch between the Lincoln Memorial and Washington Monument. The green scum has transformed one of Washington's most photographed landmarks into an environmental eyesore, disrupting the carefully manicured vista that draws millions of visitors annually.

The blooms emerged after a $14.2 million repair project aimed at restoring the pool's infrastructure. This substantial investment was intended to address longstanding maintenance issues, yet the return of algae suggests persistent water quality challenges. The pool has faced recurring problems for years, with previous restoration efforts failing to provide lasting solutions.

Repeated algal outbreaks force ongoing cleanup costs and chemical treatments, straining budgets for the National Park Service. Each bloom episode requires immediate intervention to prevent health risks and preserve the monument's aesthetic appeal. The cycle of repair and re-bloom represents a significant ongoing expense for federal preservation efforts.

Taxpayers are funding perpetual maintenance rather than permanent fixes, highlighting the challenge of sustaining historic landmarks in urban environments. The Reflecting Pool serves as a symbol of broader infrastructure maintenance failures across federal properties.
