Science Has a Name for What’s Plaguing the Reflecting Pool

TL;DR

  • The Reflecting Pool is infested with a new type of green algae called Scenedesmus, nicknamed 'Skinny Dead Mouse' by scientists.
  • Previous treatments to kill off blue-green algae have inadvertently fostered the growth of Scenedesmus.
  • The water in the pool appears murky and oily in some sections, with the original blue color replaced by shades of green.
  • Transparency regarding water safety tests from the Department of Interior and National Park Service is lacking.
  • Scientists suspect the pool's design, including its shallow depth, ample sunlight, nutrients, and dark blue paint, makes it an ideal environment for algae growth.
  • The sealant from the pool's recent $16.4 million renovation project is also beginning to peel off.
