President Donald Trump’s plan to clean up the Lincoln Memorial Reflecting Pool might be as effective as his promise to drain the swamp.On Friday, The New York Times published a report that found the president’s renovation of the historic landmark ignores a “major underlying issue” that could make the whole project a costly waste of money: There’s no plan to fix its leaky pipes.Helicopter shot of the National Mall in Washington, D.C., in 2024.halbergman via Getty ImagesThe crux of the issue seems to be that the body of water has been plagued with algae for years — with passersby describing it as “really sludgy,” “disgusting” and smelling of “wet dog” to CNN in 2012. Algae sits in the Reflecting Pool in front of the Lincoln Memorial after recently being filled with water.Mark Wilson via Getty ImagesIn April, Trump announced a plan to make the pool great again by scrubbing and grouting its granite and then covering it with an “American flag blue”-hued waterproof coating, reminiscent of an actual swimming pool. Virginia firm Atlantic Industrial Coatings was awarded a no-bid contract to do the work, which Trump initially said would cost $1.8 million. Yet, it was reported in May that the company jacked up the price to $13.1 million in an effort to finish the job before America’s 250th birthday celebrations, per Trump’s request.Construction work continues to seal the bottom of the pool on the National Mall on Friday in Washington, D.C.Kevin Carter via Getty ImagesThe Times points out, however, that Parks Services told Trump during his first term that “the only solution” to the pond scum issue “was to replace thousands of feet of pipe.” These pipes, that lay underground in the surrounding parkland, are meant to move large volumes of water from the pool to a treatment center — where algae and bacteria is killed through a filtering and purification process — and then pumped back into the pool. The problem, according to the Times, is that Park Services says the pipes’ “plastic walls fail under pressure from the surrounding soil” causing them to break and leak. When the pipes leak, the pool has to be shut off, and water is cut off from the filtration system for weeks, giving the algae plenty of time to slime.The firm currently working on the pool, however, is not working on the pipes but are concentrating on a “system of expansion joints around the pool’s concrete slabs.” Workers spray blue paint on the bottom of the Lincoln Memorial Reflecting Pool on Thursday in Washington, D.C.
