The Reflecting Pool at the Lincoln Memorial in Washington D.C. has turned a yellowish-green color just days after the completion of a $16 million renovation project. The discoloration is due to a significant algae bloom. Officials have not yet commented on the cause of the bloom or a timeline for restoration of the pool’s clear water. The renovation, intended to improve the pool’s infrastructure, was recently finished and celebrated as a restoration of a national landmark. Images and video of the altered water have circulated online, drawing attention to the unexpected issue. The National Park Service is expected to address the situation and determine the necessary steps to rectify the water quality. This incident raises questions about the long-term effectiveness of the renovation and potential ongoing maintenance needs.
