Original story
The National Park Service is working to eliminate the algae growth in the Lincoln Memorial Reflecting Pool. The algae appeared weeks after the pool’s August reopening.
The pool underwent a two-year renovation that used approximately $30 million from the American Recovery and Reinvestment Act, The Eagle previously reported.
The algae grew due to low ozone levels in the pool’s filtration system, according to NPS spokesperson Carol Johnson. NPS has more than doubled the ozone levels to kill algae and prevent new growth.
“The calibration wasn’t quite right when we started,” Johnson said.
The pool’s renovation introduced a water filtration system that draws water from the D.C. Tidal Basin and adds ozone to the water, according to the Washington Post.
The NPS plans to continue skimming algae from the pool until it is clean.
