Lincoln Memorial reflecting pool full of algae

September 26, 2012 (WASHINGTON)

Large amounts of algae are mucking up the pool, despite the two-year, $34 million renovations.

Officials say that they expected a "break-in period" for the pool but that there is much more algae than anticipated.

Luckily, it doesn't pose a health risk, and park service workers can solve the problem with a simple chemistry change.
