Potomac sewage spill: Repairs to take weeks longer after large rocks found in pipe

The blockage inside the collapsed sewer line that sent hundreds of millions of gallons of sewage into the Potomac River is worse than previously thought, and it’s going to take weeks longer to repair, DC Water officials said.

It will likely take an additional four to six weeks to get a system in place to safely remove large rocks and boulders crews found inside the sewer line during an overnight inspection, DC Water said in an update early Friday morning.

“Standard cleaning methods using industrial vacuums and jets are not sufficient to remove these large boulders,” DC Water said. “Addressing this blockage will require both larger machinery and manual labor. Workers will need to safely enter the pipe, use slings to maneuver around the rocks, and then rely on heavy equipment to extract each boulder, making removal a complex and highly specialized operation.”

The “large rock dam” stretches about 30 feet downstream of the original pipe collapse, the agency said.

According to DC Water, the rocks were likely excavated during the pipe’s construction in the 1960s and used as backfill. When the pipe failure happened last month, the rocks were drawn in by the force of the wastewater flow.

Then, as the surrounding material eroded into the sinkhole created by the collapse, extra rocks and soil accumulated and filled the pipe, helping create the rock dam.

DC Water said its bypass pump system near the spill has mostly contained the overflow of wastewater, but hasn’t stopped it. Reducing the flow of water through the pipe further means adding more of those pumps, DC Water said.

University of Maryland researchers say the spill spewed harmful bacteria as far as 10 miles downstream from the sewage overflow site.

The bacteria now in the Potomac River water, according to those UMD researchers, includes E. coli, the bacteria behind Staph infections and the antibiotic-resistant form of Staph known as MRSA.

To make matters worse, the cold water and outdoor temperatures are acting like a refrigerator, keeping the bacteria alive for longer as it travels downstream.

News4 Meteorologist Ryan Miller explained how the colder temperatures may be slowing the natural cleansing of the river from the spill.

“The water temperature right now is 39 degrees,” Miller told News4’s Mark Segraves. “That’s refrigerator temperature water. And that water will help to slow the growth of the bacteria, prevent the die-off, a massive die-off of the bacteria. So from that standpoint, the cold water can actually help transport further distances some of the pathogens.”

UMD officials urged anyone who comes in contact with the water to get tested.

DC Water is also conducting water quality sampling at multiple locations to check for E. coli bacteria, and also found elevated levels after the spill.

The spill took place below the point in the river where D.C.’s drinking water comes from, which means the D.C. water supply has not been impacted and is safe, according to DC Water.

It’s been more than two weeks since the sewer pipe collapsed on Jan. 19, causing 300 million gallons of sewage and wastewater to flow into the Potomac River.

‘It’s a twilight zone’: Iran war casts deep shadows over IMF gathering in Washington

‘It’s a twilight zone’: Iran war casts deep shadows over IMF gathering in Washington

The most severe energy shock since the 1970s, the risk of a global recession and households everywhere stomaching a renewed surge in the cost of living – hitting the most vulnerable hardest.

In a sweltering hot Washington DC this week, the message at the International Monetary Fund meetings was chilling: things had been looking up for living standards around the world. But then came the Iran war.

“Some countries are in panic,” said the fund’s managing director, Kristalina Georgieva, addressing the finance ministers and central bank bosses in town for the IMF and World Bank spring meetings. “The sooner it [the Iran war] ends, the better for everybody.”

Such gatherings are not typically used to fight geopolitical battles. “You don’t get people shouting at one another at these things,” one senior figure remarked. But, as a record-breaking April heatwave swept the US capital, no one could ignore the mounting damage from the Iran war.

Those familiar with the mood over breakfast at a meeting of the G20’s representatives on Thursday, which included Donald Trump’s treasury secretary, Scott Bessent, and the outgoing US Federal Reserve chair, Jerome Powell – said the atmosphere in the room was sombre amid an open exchange of serious views.

“It is such a twilight-zone meeting,” said Mohamed El-Erian, a former IMF deputy managing director who is now chief economic adviser at the Allianz insurance group. “There are several shadows hanging over it: one is the shadow that comes from concern about the global economy as a whole.

“The second is that some countries are going to be particularly hard hit, and it’s mostly countries that very few people are talking about. But the third concern is the adding of insult to injury: the fact that the US, which started a war of choice, is going to be hit, but by a lot less than elsewhere in relative terms.”

Before Thursday’s breakfast, Rachel Reeves had started her day with an early-morning jog. Joined by her counterparts from Spain, Australia and New Zealand for a run down the iconic National Mall, she posted an Instagram selfie with a not-so-subtle dig: “Friends that run together – work together.”

A day earlier, the chancellor had told a CNBC conference that she thought “friends are allowed to disagree on things” as she criticised Trump’s Iran war as a “mistake” and a “folly” that had not made the world safer.

Speaking at a venue just steps away from the White House, before a one-on-one meeting with Bessent, she said this “fair message” was needed because UK families and businesses were feeling the pain from higher energy prices triggered by the conflict.

Those close to Reeves insist her meeting remained cordial. Britain and the US have significant shared interests in AI, financial services and trade. The chancellor also said the UK government had little time for the Iranian regime.

But with the IMF having warned on Tuesday that the Iran war could risk a global recession – in which Britain would be the biggest G7 casualty – it was clear Reeves had travelled to Washington ready to pick a fight.

“I’m struck by how vocal she has been and the words she used,” said one global financier. “We know the disagreement between Bessent and [European Central Bank president] Christine Lagarde earlier in the year. But that was in private.”

At a cocktail party held at the British ambassador’s residence for hundreds of diplomats and financiers – including the Bank of England’s governor, Andrew Bailey, the chief executive of Barclays, CS Venkatakrishnan, and dozens of senior figures – this transatlantic tension, weeks before King Charles’s US state visit, was a major topic of conversation.

The other, in the balmy residence gardens, was one of its former occupants, Peter Mandelson, as revelations about the former ambassador’s appointment threatened to further rock the UK government.

Before the war, the agenda for the IMF had been about global cooperation; the adoption of AI, jobs and work to eradicate poverty. Each of those tasks had now been complicated, but not least the task of countries working together.

For many at the meetings, the focus was on forging closer global cooperation without the world’s pre-eminent superpower.

“Everybody is talking about how you hedge against American decisions,” said David Miliband, the former UK foreign secretary, who now runs the International Rescue Committee. “You can’t do without them, because they’re 25% of the global economy. But, in a lot of fora, they’ve pulled out.

“So everyone has to think, how does one structure international cooperation? The old west is not coming back. And so everyone has to figure out how to position themselves for that world.”

For those gathering in Washington, there was irony in the fact that they were meeting in the halls of institutions founded, under US leadership, to promote global cooperation after the second world war. The whole idea of the Bretton Woods institutions was to avoid the dire economic conditions and warfare of the 1930s and 1940s. Yet this year’s meeting was taking place amid these intertwining problems.

In their conversations about the best economic policy response to the shock of conflict, the economists also knew the real power to make a difference lay two blocks across town from the IMF and the World Bank – behind the security cordons and construction equipment blocking the White House from public view. “It is not clear they can do anything about it,” said El-Erian.

Still, with a booming economy driven by AI – including Anthropic’s powerful Mythos model, the topic of much conversation – most countries cannot afford to completely break off US ties.

“People want to find ways to insulate themselves from the mess. But, on the other hand, they admire the US private sector,” El-Erian said. “The best way I’ve heard it put, is: they want to go long the private sector and short the mess. But it’s almost impossible to do.”
