The Reflecting Pool on the National Mall has already begun to grow algae just days after President Donald Trump’s major renovation project was officially completed.
The landmark has been the subject of controversy since the project began, with critics pointing to budget ballooning from a little under $2 million to a staggering $14 million. Trump contracted Atlantic Industrial Coatings for the project to be completed ahead of the celebrations for the 250th anniversary of America.
Part of having a dark bottom is that you cannot tell that the water is green. Birds poo in these things, filling them with nutrients that the algae gobble up.
