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.

Pop-up museum in DC features the scandal that changed American history – WTOP News

Pop-up museum in DC features the scandal that changed American history – WTOP News


Among the liquor store, barber shop and dry cleaners at the Watergate Complex’s retail plaza, there is a new pop-up museum dedicated to the scene of the crime that toppled Richard Nixon’s presidency.

Among the liquor store, barber shop and dry cleaners at the Watergate Complex’s retail plaza, there is a new pop-up museum dedicated to the scene of the crime that toppled Richard Nixon’s presidency.

The temporary exhibit features the work of artist Laurie Munn — portraits of members of the Nixon administration and those connected to the Watergate break-in. The exhibit features members of Congress, the media and some who were on Nixon’s enemies list.

Keith Krom, chair of the Board of Directors of the Watergate Museum, told WTOP the exhibit was first featured in the gallery in 2012 for the 40th anniversary of the break-in at the Democratic National Committee.

“When she (Munn) learned about our museum effort, she offered to reassemble them as a way for us to expand awareness of the museum,” Krom said.

Krom, who lives in the Watergate, said his favorite portrait is of one of the special prosecutors, whose firing sparked the “Saturday Night Massacre” in 1973.

“I had the pleasure of being a student of Archibald Cox,” Krom said. “He served as my mentor for my third-year writing project.”

Krom said during this time, at the Boston University School of Law, he spent a great deal of time with him.

“I didn’t realize how much he must have gone through. Here he was, this one man, who was challenging the president of the United States over something pretty serious,” Krom said.

The pop-up opened in October and was recently extended to stay open until April 25. Krom said the hope is to find it a permanent location within the Watergate Complex, where they can “present the history of Watergate, but with two perspectives.”

The first would be on the building’s “architectural significance to D.C.,” he said.

“You may not like the design, you actually may hate it,” Krom said. “But you cannot deny that it changed D.C.’s skyline.”

The secondary focus would, of course, be on the mother of all presidential scandals that changed the course of American history.

“That’s where that suffix ‘-gate’ started and continues to be used for almost every scandal that comes out today,” Krom said.

The inspiration for the museum spawned from an interaction from a tourist outside the Watergate.

“He says, ‘This is the Watergate, right?’ And I was like, ‘Yeah, it’s one of the buildings,’” Krom recalled.

The tourist then asked Krom, “So where’s the museum?”

“I was like, ‘Oh, we don’t have a museum.’ And he literally just looked at me and said, ‘That’s so sad.’ And he got on his bike and rode away,” Krom said.

While the self-proclaimed political history nerd said he “still gets goose bumps” when he drives by the Capitol at night, Krom hopes that when people leave the museum, “they’ll walk away with a new appreciation for how our government works, the guardrails that are in place.”

“Maybe an understanding that those guardrails themselves are kind of frail, and they probably need our collective help in making sure they last — that’s what we hope to accomplish,” Krom said.

Cherry Blossoms Hit Peak Bloom in Washington DC

Cherry Blossoms Hit Peak Bloom in Washington DC


Almost at peak! A view of the cherry trees in Washington DC show they’re about to burst into peak bloom very soon. Image: NPS

According to the National Park Service at the National Mall, famous cherry blossoms around the nation’s capital have hit peak bloom conditions. The National Park Service X account for the National Mall proclaimed this morning, “PEAK BLOOM! PEAK BLOOM! PEAK BLOOM!”

It became apparent yesterday that the bloom would be at peak today. “Despite a sunny afternoon and patches of blue sky, the cherry blossoms remain at Stage 5: Puffy White,” the Park Service wrote on X yesterday.  Stage 5, “Puffy White”, is the final stage blossoms go through before being in full bloom. They start at Stage 1 as a “Green Bud”, grow into Stage 2 with “Florets Visible”, and then florets become extended at Stage 3. In Stage 4, there is “Peduncle Elongation” which sets the stage for the puffy blossoms to appear in Stage 5. Puffy White and Peak Bloom are defined as when 70% of the blossoms on the trees reach that stage.

Peak bloom varies annually depending on weather conditions; the most likely time to reach peak bloom is between the last week of March and the first week of April. According to the Park Service, extraordinary warm or cool temperatures have resulted in peak bloom as early as March 15 in 1990 and as late as April 18 in 1958.

The planting of cherry trees in Washington DC originated in 1912 as a gift of friendship to the People of the United States from the People of Japan. In Japan, the flowering cherry tree, or “Sakura,” is an important flowering plant. The beauty of the cherry blossom is a symbol with rich meaning in Japanese culture.

Dr. David Fairchild, plant explorer and U.S. Department of Agriculture official, imported seventy-five flowering cherry trees and twenty-five single-flowered weeping types from the Yokohama Nursery Company in Japan. After experimenting with growing them on his own property in Maryland, he deemed that the cherry tree would be perfect to plant around the Washington DC area. This triggered an interest by a variety of individuals to plant the tree around Washington.  In 1909 the Mayor of Tokyo, Yukio Ozaki, donated 2,000 trees to the United States on behalf of his city. When the trees arrived, they were riddled with disease and insects and to protect other agriculture, they were burned. The Tokyo Mayor made a second donation of trees in 1910, this time amounting to 3,020 trees.  This started the forest of cherry trees that now line the Potomac basin around Washington DC. In a gesture of gratitude back to Japan, President Taft sent a gift in 1915 of flowering dogwood trees to the people of Japan.   Thousands of trees have been added since, including another gift of 3,800 trees from Japan in 1965.
