Army Corps: Reservoir expansion ‘doesn’t fix, but improves’ DC’s drinking water supply for future Potomac River emergency – WTOP News
Developing a regional solution to enable all local water companies to share drinking water in the event of a future Potomac River emergency remains a long-term challenge facing the U.S. Army Corps of Engineers.
Developing a regional solution to enable all local water companies to share drinking water in the event of a future Potomac River emergency remains a long-term challenge facing the U.S. Army Corps of Engineers. But the Corps is leaning-in to near term solutions, for now, because current issues “are quite, quite dire.”
In an interview with WTOP, Trevor Cyran, Chief of the Civil Works project management office of the Baltimore District Corps of Engineers, elaborated on the Corps’ ongoing three-year feasibility study funded by Congress and the Metropolitan Washington Council of Governments.
Last week, during a House Transportation and Infrastructure Committee hearing, lawmakers pressed the U.S. Army Corps of Engineers to explain what’s being done to secure solid backup options for the D.C. region’s drinking water.
D.C. Del. Eleanor Holmes Norton challenged the Corps after learning that the study that Congress authorized to identify a secondary water source for the region was being narrowed to only expanding the current Dalecarlia Reservoir, adjacent to the Washington Aqueduct, which remains the only source of drinking water for D.C., Arlington, and parts of Fairfax County, Virginia.
“Expansion of the reservoir is not a secondary water source,” Norton said. “With only a one day of backup water supply, human-made or natural events that make the river unusable would put residents, the District government and the regional economy at risk.”
Cyran said the U.S. Army Corps of Engineers doesn’t disagree.
“We’re trying to find a quick win that addresses some of the near-term issues, because they are quite, quite dire,” Cyran said. “The Dalecarlia expansion would add approximately 12 hours of water storage into the system,” he said. “So, while we know that doesn’t fix the problem, it improves the situation.”
Recently, drinking water in D.C., Northern Virginia and Maryland has remained safe because the January collapse of a portion of the aging Potomac Interceptor regional sewer line happened downstream of the main Potomac River water intake serving the Washington Aqueduct.
“We’ve moved forward with the Dalecarlia expansion, as our most probable recommendation,” said Cyran. “The Corps is laser focused on delivering something right here, right now that can actually help with the issue, while still exploring some of those long term solutions.”
Cyran said the dangers to public health and the economy are substantial, with the Potomac as the sole drinking water source. “It’s not a great situation — we’ve seen a very real risk come to fruition recently, with the spill.”
While drinking water has been unaffected by the spill, the advisory for the public to avoid contact with the Potomac River remains in effect in the District and Montgomery County, where the Potomac Interceptor spill happened, along the Clara Barton Parkway.
The advisory is expected to be lifted Monday, by the D.C. Department of Health, as E. coli levels have recently returned to the typical range for D.C.’s rivers. The District’s Department of Energy and Environment is now doing daily testing of the Potomac and Anacostia Rivers.
How would increased storage at Dalecarlia Reservoir look?
According to the Army Corps, expanding the Reservoir over 54 available acres would provide approximately 70 million gallons per day, doubling the capacity at Dalecarlia. Since the land is already owned by the Washington Aqueduct, it would not require acquiring any land.
Cyran said it’s not yet certain whether the expansion would provide an extra 12 hours of storage of raw water from the Potomac, or finished water, after it had gone through the Washington Aqueduct’s water purification process.
Regardless, either option would result in the Aqueduct having more water on hand, if drawing water from the Potomac was suddenly unsafe.
Another near-term option that wouldn’t require land acquisition would be advanced treatment, Cyran said.
“We could implement something that allows us to treat for a wider array of contaminants, if you had a spill,” said Cyran, although noting the recent spill from the Potomac Interceptor, which poured approximately 240 millions of raw sewage into the Potomac, “might not be a good example” of how the technology would work.
The Army Corps list of possible solutions includes reusing water. In November 2025, DC Water outlined its own plans to recycle water from the utility’s Blue Plains Advanced Wastewater Treatment Plant, the largest of its kind in the world.
Quarry storage cannot happen quickly
During its ongoing study, the Army Corps has identified possible long term regional solutions, including the potential use of the Travilah Quarry in Montgomery County, Maryland, and two quarries in Loudoun County, Virginia, owned by Luck Stone.
10 years ago, in December 2016, WTOP first reported that the Travilah Quarry, located on Piney Meetinghouse Road in Rockville, was quietly being considered by DC Water, WSSC Water, and Fairfax Water, as an alternative source of water, if the Potomac River were unavailable.
“The three utilities, and the Interstate Commission on the Potomac River Basin, along with the Metropolitan Washington Council of Governments have been working over the last several years to look at alternatives to get better interdependencies, to have more resilience in our system,” said Tom Jacobus in 2016, while he was general manager of the Aqueduct.
Now, a decade later, the logistical, real estate, and financial challenges of obtaining a quarry which could be interconnected between DC Water, WSSC Water, and Fairfax Water remain.
“We’re not saying they can never happen, we’re just saying they cannot, in any way, shape, or form, happen quickly,” said Cyran. “Travilah is still an active quarry, so that can’t even be considered for storage until they’re done mining, which might be 30 years from now.”
The Dalecarlia Reservoir expansion would not be regional solution, Cyran said.
“That would only benefit folks who are tied directly to the Aqueduct at this time,” he said. “However, while we’re going to be looking at other alternatives that we could potentially spin off and continue to look at, that would address some of those more regional issues.”
‘We can’t hand half-baked ideas to Congress’
While an interconnected, resilient system, that could provide additional water sources and storage to DC Water, WSSC Water, and Fairfax Water would be optimal, Cyran said the Corps is limited by a Congressional paradigm that limits its feasibility study to four years and five million dollars.
“We can’t hand half-baked ideas to Congress,” Cyran said.
With the Corps’ current focus of implementing near-term improvements, quickly, the agency will continue to use its expertise to envision a more resilient, long term solution.
“We are committed to looking at this issue and try to explore some regional solutions, within the paradigms of the legislation that we have to operate within,” said Cyran. “If Congress wants to consider something else to expand our authority, we could maybe look at a bigger solution, with more time and money.”

Mom finds out daughter with autism was sexually abused at DC school week after it happened
CONTENT WARNING: This story contains content that may be uncomfortable to some readers. Discretion is advised.
WASHINGTON (7News) — A mother said she learned her 13-year-old daughter was sexually abused in a D.C. school when a detective contacted her a week after it happened. She said the school never notified her.
7News sat down with the mother on Friday, while her daughter was being evaluated and interviewed by detectives. We’re not sharing the mom’s identity to protect her daughter.

The mom said she got a call Sunday night, “regarding my daughter and a sexual assault that happened at school involving my daughter last Monday.”
However, it didn’t come from the place or people she said she counted on.
“I never got a phone call from the school, an email, a text, nothing to say,” said the mom. Nothing happened until a week later.
That’s when a detective called and told her what happened.
“She was forced to give oral sex to a student in school,” said the mom.
Her 13-year-old daughter is disabled, autistic, and has challenges communicating.
The mom said she was sending her daughter to school without knowing what happened.
“I noticed a little behavior, emotional changes,” said the mom. “When I got that call now, it makes sense to, you know, what you because of what she had experienced at school and to come home and she didn’t say anything or no one had called me and just like it breaks my heart.”
7News obtained a copy of the police report, which confirms the youth investigative branch is investigating what happened to her daughter as sexual abuse. It shows that a Kelly Miller Middle School social worker reported it to the Metropolitan Police Department (MPD) last week.
“I just hope that I can be able to get her back on the right track. From all the trauma, on top of trauma,” said the mom. “To be able to grow and not have to hold that in the back of her head that she experienced in school, which should have been her safe place.”
7News started reaching out to DCPS just after 12:30 p.m. to ask if the students suspected of the abuse have been removed from the school, and why parents wouldn’t have been notified about the incident. They did not get back to us until after our first report aired. They did not answer either question. They provided the following statement.
A district spokesperson provided this statement:
At DC Public Schools (DCPS), student safety and wellbeing are paramount, and the district treats any allegation of sexual misconduct with the utmost seriousness. DCPS will continue to cooperate with law enforcement as this matter is investigated.
In accordance with the Family Educational Rights and Privacy Act (FERPA) and our obligation to maintain student confidentiality, we are unable to provide comment on individual student cases.
If you or someone you know is a victim of sexual assault or abuse, the National Sexual Assault Hotline can be accessed by calling 1-800-656-4673.

The hacking group posted online that nearly 9,000 schools worldwide were affected, with billions of private messages and other records accessed. Many school systems and universities in the Washington, D.C. region rely on Canvas as their primary learning management system.
In Montgomery County, school officials said access to the platform will remain unavailable “out of an abundance of caution” while they work to understand the impact of the incident and any potential vulnerabilities. Families were urged not to log in until MCPS and the myMCPS Classroom vendor resolve the issue.
The University of Maryland said it does not yet know when Canvas will return to service.
Canvas Cyberattack DC-Area School Systems Affected
Montgomery County Public Schools
Canvas (myMCPS Classroom) owned by Instructure Inc., is used by the school district as its learning management system. Due to a reported global cybersecurity concern involving Canvas, and impacting numerous school systems, universities, corporations in Maryland, other states, and worldwide, thus access to myMCPS Classroom has been disabled.
Out of an abundance of caution, access to the system will remain unavailable while we work to better understand the full impact of the incident and any potential vulnerabilities involving information connected to the platform. Please do not attempt to log in to the platform until MCPS and the myMCPS Classroom (Canvas) vendor have resolved this problem.
At this time, appropriate MCPS technology and security staff are continuing to assess the situation and coordinate with the vendor. We understand this disruption is frustrating and appreciate your patience as this work continues.
myMCPS Classroom provides access to student information such as grades, assignments, attendance, and course materials, and is an important tool for students and families to monitor academic progress. Additional information on how students can access resources and functions in myMCPS Classroom will be provided as soon as possible.
Updates will be shared as soon as additional information becomes available.

Canvas may appear to be up right now, but please to not use it. DIT Security is not confident the system is safe to use right now. Please check back here before using Canvas.
For our faculty who use Canvas, we have created this guidance, and we will continue adding resources tomorrow. Please stay in touch with your students as we adapt to this evolving situation.
Prince George’s County Schools
There has been a cybersecurity incident involving Canvas, our Learning Management System.
Instructure, the parent company of Canvas, notified us of a global cybersecurity incident affecting 275 million users across numerous educational institutions. We have been informed that PGCPS was one of the many impacted organizations. While personal information including names, emails and Student IDs was impacted, NO sensitive information, such as dates of birth, passwords, financial information, was involved. PGCPS does not store that type of sensitive information or parent information in Canvas.
We are using this as an opportunity to reinforce the importance of exercising caution when communicating by email and remaining vigilant regarding suspicious messages, spam, phishing attempts, or other potentially fraudulent communications.
We will continue to monitor the situation and remain in close communication with Instructure.
Anne Arundel County Public Schools
Due to the ongoing issues with the Canvas Learning Management System (LMS), AACPS will operate schools on Friday, May 8, 2026, without the use of the LMS. The Virtual Academy will also remain open with altered instructional delivery that will also not use the LMS. Further instructions will be communicated from the school principal. The latest information regarding the breach and the status of school district operations can be found at www.aacps.org/canvasbreach.
Prince William County Public Schools
We are aware of the error appearing when accessing Canvas and are actively working with the vendor to resolve it. The issue is not just impacting PWCS, and is widespread and national in scope. We will provide updates when the vendor has resolved the issue.
