WORKERS have been spotted clearing bright green algae from the Reflecting Pool just days after its $14million makeover was completed.

The unsightly clumps appeared shortly after Donald Trump hailed its newly filled water as “beautiful” and “clean.”

Crews were seen tackling the problem at the famous Washington, DC, landmark after algae spread across several parts of the pool.

Green patches coated the bottom near both the Lincoln Memorial and World War II Memorial and were also floating on the surface.

One patch near the World War II Memorial appeared to grow significantly between a rainy Wednesday and a hot and humid Thursday.

Photographers captured workers clearing the muck and buckets of Induclor beside the water, the Washington Post reported.

The chlorine compound is used to control algae, bacteria, slime and fungi.

The Interior Department insisted the outbreak was part of the normal process of restarting the pool after construction.

“What you are seeing is residual algae from the supply lines which have been sitting dormant for eight weeks while construction has been taking place,” spokesperson Katie Martin said.

“It’s part of the normal startup process.”

Martin said workers were removing the algae and claimed newly installed nanobubblers would stop it from returning.

She added: “President Donald J. Trump is an expert builder who has fixed the Reflecting Pool for good unlike the failed and extremely costly attempt by Obama and Biden.”

Trump continued to praise the renovation on Thursday and said the new surface had solved the pool’s long-running leaks.

“It always leaked because it was done in stone,” he told reporters in the Oval Office.

“Now it’s done properly. It’s not going to leak at all.”

White House spokesperson Taylor Rogers also defended the work when asked about the green buildup.

“President Trump used his expertise to deliver exquisite upgrades to the Lincoln Memorial Reflecting Pool that Americans will enjoy for years to come,” she said.

“The public supports these long-overdue improvements to our nation’s capital, and hit pieces like this are exactly why trust in the media is at an all-time low.”

Trump announced the resurfacing project on April 23 and initially said it would take about one week and cost less than $2million.

The work instead lasted six weeks and ultimately cost more than $14million.

Historic preservationists have filed a lawsuit claiming the administration bypassed public-comment requirements and other necessary procedures.

Democrats have also demanded answers over the use of no-bid contracts and the speed of the president’s construction projects.

Senator Richard Blumenthal warned of “troubling patterns of waste, fraud, and abuse” in a letter to National Park Service leaders.

Trump has repeatedly called the pool’s previous condition “filthy” and “disgusting” while claiming the revamp would last decades.

“I’m looking at the Washington Monument and this thing is terrible,” he said last month.

“The water is dirty, there’s cartons of stuff in it, and everything is just so horrible.”

He added: “It’s a much better job. This will last for at least 50 years and you’ll never have a leak.”

Algae has repeatedly plagued the shallow pool and quickly returned after a separate $34million renovation completed in 2012.

The organisms thrive in heat and sunlight and are normally controlled through filtration, chlorine, algaecide and tiny oxygen-filled nanobubbles.

The basin’s new “American Flag Blue” coating has kept its mirror-like appearance from a distance.
