# Trump Administration Tackles Algae Bloom at Reflecting Pool With Hydrogen Peroxide Treatment The Lincoln Memorial Reflecting Pool, recently reimagined with a vivid blue bottom under Trump administration direction, has developed a significant algae bloom—a common maintenance challenge at one of Washington's most iconic sites. Park service personnel responded with hydrogen peroxide and aeration equipment Tuesday, attempting to restore the water's clarity and the visual impact of the renovated pool before the discoloration became entrenched. The algal bloom represents a collision between aesthetic ambition and ecological reality. The newly installed blue bottom coating was designed to enhance the pool's visual appeal and align with what administration officials characterized as an "American flag blue" aesthetic—a deliberate design choice that departed from the pool's historical appearance. Yet this darker bottom, combined with Washington's warm spring conditions and the pool's relatively stagnant water system, appears to have created ideal conditions for rapid algae growth. Hydrogen peroxide is an established algaecide that breaks down organic matter while dissipating into water and oxygen—a pragmatic choice that avoids long-term chemical accumulation. The introduction of aeration bubbles addresses the root problem: oxygen-depleted water encourages algal proliferation. These interventions suggest park service officials were treating the symptom while acknowledging the underlying water quality issues. The episode illustrates broader tensions in monument maintenance. Historic sites like the Reflecting Pool require constant attention to water quality, vegetation, and structural integrity—needs that don't pause for aesthetic renovations. The pool's relatively closed system, fed primarily by groundwater and rainfall, makes it vulnerable to nutrient buildup and algal blooms regardless of pool color. Some water management experts argue that the darker coating may intensify water temperature fluctuations, potentially exacerbating biological growth cycles. However, without detailed analysis of the pool's historical maintenance records, it remains unclear whether this particular bloom exceeds typical seasonal patterns or represents a novel problem introduced by recent changes. Park service data on pre- and post-renovation algae incidents would provide necessary context. The response itself—swift deployment of tested chemical and mechanical treatments—indicates that relevant agencies possessed operational capacity to address the issue. How quickly the pool clears and whether the bloom recurs will reveal whether the hydrogen peroxide approach represents a one-time correction or the beginning of more intensive management demands tied to the design modification. **Worth knowing:** Major changes to historic site infrastructure often carry unintended maintenance consequences. Whether the Reflecting Pool's new appearance will require permanent modifications to its water management system—such as enhanced filtration or recirculation—remains to be determined by the coming weeks of observation. **Reporting:** KTAR Phoenix, Associated Press.
