A new, intensive plan to keep the Reflecting Pool on the National Mall clean is emerging after the Trump administration spent months trying to turn the iconic memorial sparkling blue at the behest of President Donald Trump.

Made internationally famous by their use to clean up the Lincoln Memorial pool in Washington, this tech is starting to be used globally.

The Lincoln Memorial Reflecting Pool appeared less swampy on June 22. Here's what else USA TODAY saw, including ducks and National Guardsmen.

The $1.7 million “ozone nanobubbler” being used in an effort to make the Lincoln Memorial Reflecting Pool water crystal clear has a unique ability to shoot 500 million microscopic bubbles into every teaspoon of water.

Bulky “nanobubbler” machines were carted off ahead of a promotional event for President Trump’s Ultimate Fighting Championship birthday party.

The Lincoln Memorial Reflecting Pool in Washington, DC has become more than a landmark. It is now a real-world testing ground for nanobubbles, microscopic gas bubbles that can clean water, control algae and may eventually help restore oxygen-starved lakes and seas.

The Reflecting Pool was green with algae just days after Trump’s $14 million resurfacing project was completed

Greenwater Services got a no-bid contract and is partly owned by a twice-convicted felon who is a Trump friend.
