Facts about the Lincoln Memorial Reflecting Pool

(source: Wikipedia)
Prompted to look this up when djt said Obama and Biden had spent $300 or $400 billion to repair the pool. Paragraphing is mine for easier reading.

Dedicated in 1922. It was completely rebuilt between 2010 and 2012.[9] The pool was originally built with an asphalt and tile bottom,[10] but was replaced with concrete in the 2009 restoration. The nearby walkways and the rim of the Reflecting Pool are also made of granite.[11]

Using funding from the American Recovery and Reinvestment Act of 2009, the National Park Service reconstructed the Lincoln Memorial Reflecting Pool.[12] Construction on the 18-month, $30.74 million project began in November 2010.

In May 2011, workers began sinking the first of 2,133 wood pilings into a 40-foot-deep (12-meter) layer of soft, marshy river clay and some dredged up material atop bedrock to support a new pool.[9] The pool's water supply system was updated to eliminate stagnant water by circulating water from the Tidal Basin; the pool was formerly filled using potable water from the city.[12]

Within weeks of the pool's reopening in 2012, it had to be drained and cleaned for $100,000 due to algae in the pool. The algae growth almost completely covered the surface of the pool.[15] Using an ozone disinfectant system installed during the renovation,[16] the National Park Service said it would double the amount of algae-killing ozone in the pool to control future outbreaks.[15]

In 2013, construction on the National World War II Memorial damaged the eastern end of the Reflecting Pool. NPS workers closed the eastern 30 feet (9 meters) of the pool in August 2015 to repair the basin, work that was completed in the summer of 2016.[17]

The Reflecting Pool was completely drained in June 2017 to control a schistosome outbreak. The parasite, which causes swimmer's itch, infected the snails that inhabited the pool, and ultimately killed more than 80 ducks and ducklings in a few weeks during spring 2017.[18]

There have been issues with the pool for quite awhile.

I find Trump's vanity about it, the humorous part. If he wasn't building a ballroom, an arch, a wrestling ring and quietly rennovated the pool without the stupid promises to kill the algae for good, then I think he would get a pass. But it's like everything else he does.....

I am enjoying this.....

like most major metropolitan areas, adds orthophosphate to the water for lead corrosion control. This is added at concentrations that are ideal for algae growth.

This PhD student in algae growth has an interesting opinion on what happened.

Since I did do my PhD in cyanobacteria growth and treatment optimization modeling AND work in the water treatment industry, I’m gonna share my theory as to what’s happening here and how to fix it.

People are focusing on the painted bottom of the pool increasing residual heat, and while that 1/19
