Your poop could give Arlington County natural gas to power buildings or buses.
The county is developing plans to upgrade its Water Pollution Control Plant, where local sewage goes. One change involves installing technology that can harness the methane emitted when human solid waste is processed, turning it into renewable natural gas, a process some municipalities have already implemented.
The energy could be used to power the wastewater plant, homes and commercial buildings or become an alternate fuel for ART buses. The “sludge” created through this process can also be used as a fertilizer for gardens, forests, farms and lawns. (If you’ve ever used Milorganite brand fertilizer, you’ve used dried sewage sludge from Milwaukee.)
Improvements to the wastewater treatment facility, to the tune of $156 million, are part of a $177 million bond request for utilities upgrades, which also includes improvements the regional Washington Aqueduct system ($15 million) and new gravity transmission mains ($3 million).
Funding for this work would come from a half-billion dollar bond referenda that voters will be considering on Election Day tomorrow (Tuesday). Over $510 million will go toward this work as well as a host of initiatives, upgrades and maintenance projects that Arlington County adopted as part of its 2023-32 Capital Improvement Plan.
Some big-ticket items have already grabbed headlines, like the $136 million requested to build a new Arlington Career Center campus and $2 million to design a proposed Arlington Boathouse on the Potomac River near Rosslyn. But there are dozens of other upgrades proposed for facilities that Arlingtonians of all ages use on a regular, and sometimes daily, basis.
Renovations to existing county buildings and the construction of new ones surpass $53 million.
- $13.1 million for various renovations to Arlington’s police headquarters and, for the county’s courts building, technology upgrades, new finishes, a redesigned entrance and a relocated Juvenile and Domestic Relations Courts division.
- $12 million to fund the construction and renovation of some floors of 2020 14th Street N. to make room for ACFD Fire Marshal and Battalion Chiefs offices and other public safety staff and functions. It will also see the replacement of the building’s 60-year-old HVAC system.
- $7.5 million to acquire land next to the Serrano Apartments to build a fire station there and improve response times on the west end of Columbia Pike, given the pace of development along the Pike.
Overall, Arlington Public Schools is asking for $165 million. Of that, some $12.24 million would pay for safer school entrances, a measure many school systems nationwide are implementing in the wake of high-profile shootings, and new kitchens to allow more meals to be made in-house.
“Upgraded kitchens will allow students to eat high-quality meals that include more fresh fruits and vegetables that are prepared on-site,” according to APS. “The entrance and security vestibule updates will comply with current safety and security standards while ensuring all visitors check in at the main office.”
Another $16.8 million would pay for a new roof for Escuela Key, the Spanish-language immersion elementary school, HVAC replacement at Hoffman-Boston Elementary School and lighting upgrades across schools.
The Arlington Dept. of Parks and Recreation is asking for nearly $22.5 million for a dozen projects.
That includes some funding $1.5 million to replace and renovate some stretches of the county’s nearly 40 miles of off-street, multi-purpose trails, 56 pedestrian bridges and 11 low-water fords.
Preschool- and school-aged kids could have new playgrounds at Bailey’s Branch, Monroe and Woodmont parks sometime in 2024 ($2.8 million). Douglas Park will see $2 million in improvements, including a new picnic shelter, pedestrian bridge, stormwater management, invasive species removal and reforestation.
Athletes who play at Kenmore Middle School could have new turf fields ($300,000).
There’s $1.1 million in funding to design new facilities at Short Bridge Park, near the border of the City of Alexandria, as well as $1.8 million to redesign Gateway Park in Rosslyn, which the budget says is “difficult and dangerous to access due to the surrounding high-speed roadways” and is “under-utilized.”
People who live in the Ballston and Virginia Square areas would be able to get in on the ground floor of master planning processes ($1.5 million) next year to upgrade Maury, Herselle Milliken and Gum Ball parks starting as early as 2025.
The second, $4.4 million phase of work on Jennie Dean Park will move forward, including demolishing the existing WETA building, two parking lots and a portion of 27th Street S., installing a lighted basketball court and converting the existing court for tennis use.
The growing pickleball population, sometimes at odds with neighbors, and the dirt trail-less mountain bike enthusiasts could get new facilities through $2 million to convert tennis courts at Walter Reed Community Center for pickleball use, draw pickleball lines on some multi-use courts and fund “design improvements to natural surface trails and mountain biking improvements.”
For the last two months, Arlington County has been getting your sewage tested to measure community Covid infection levels.
The Department of Environmental Services is sending weekly samples to Biobot, a Massachusetts-based health tech startup that got its start monitoring wastewater for opioids but pivoted to COVID-19 testing during the pandemic. The company now tests wastewater samples for municipalities nationwide.
Wastewater surveillance is seeing more interest as reported Covid testing rates wane and the focus of the federal government and some cities shifts from counting Covid cases to tracking hospitalization rates. Indeed, wastewater surveillance is one way the Centers for Disease Control is tracking the rise of the new Omicron subvariant BA.2, now the dominant Covid strain in the nation.
“The case counts aren’t as reliable as they used to be, so we’ve seen more interest in wastewater analysis as an unbiased look at what’s going on in their communities,” Biobot’s Jennings Heussner tells ARLnow. “People aren’t getting tested because they’re being tested at home, they don’t know they’re sick, or they don’t feel the need to get a test — they feel poorly and decide to stay home.”
Even if people stop seeking out tests, there is one place where their viral load will show up: the toilet.
“You start shedding the virus in your fecal matter at the point of infection,” Heussner said. “That increases until you become symptomatic and then begins to fall off from there. You have a window of — it varies from person to person — up to a week before you know you’ve been sick that you’ve been shedding the virus in your fecal matter.”
Biobot uses PCR testing to ascertain the concentration of viral RNA per milliliter of sewage, which is the unit it reports on its webpage. Regular wastewater samples can give municipalities anywhere from a two to 10 days’ heads-up of what might be coming in terms of community infection levels, before the infections show up in testing data, Heussner said.
According to the Virginia Dept. of Health, the average rate of new cases in Arlington hit a seasonal low point on March 6. Biobot’s wastewater data, meanwhile, hit its low point two days earlier, on March 4.
The local case rate has since nearly doubled, rising from 24 daily cases on March 6 to a seven-day moving average of 46 daily cases today, according to VDH data. Biobot’s wastewater data, meanwhile, continues to point to an upward trajectory of infections in Arlington.
Most cases in Northern Virginia stem from the dominant Omicron variant, with subvariant BA.2 comprising a growing portion of total case numbers, according to a new state dashboard tracking variants of Covid. Biobot can detect which variants are present, although that information is currently not available for Arlington.
As for the gap in wastewater sampling data on the chart above, Heussner said Biobot received samples from Arlington County last summer through a collaboration with the U.S. Department of Health and Human Services. Sampling stopped when that partnership ended, until Arlington again began sending samples in February.
While the county is submitting wastewater to weekly testing, it is not rushing to adopt this method as a gold standard for tracking the virus.
“The Arlington County Public Health Division reminds everyone that wastewater surveillance for the virus that causes COVID-19 is a developing field,” public health spokesman Ryan Hudson said. “Wastewater testing over time may provide trend data that can complement other surveillance data to inform decision-making about the response to COVID-19.”
He noted that currently, wastewater testing cannot “reliably and accurately predict” the number of infected individuals in a community.
“As for the uptick in cases, now is the time to get your COVID-19 booster if you haven’t,” Hudson said. “It is recommended that everyone 12 years and older receive the appropriate booster doses of the COVID-19 vaccine.”
(Updated 5:45 p.m.) Washington-Liberty High School senior James Licato is trying to clean up micropollutants in the Potomac River, and he came up with a solution that vaulted him to the finals of a major science competition.
Licato is one of 40 finalists in the Society for Science’s Regeneron Science Talent Search 2021, the nation’s oldest science and math competition for high school seniors. He developed a sandy substance, using zeolites, that acts as a microscopic net, catching the micropollutants that wastewater treatment facilities miss.
Chosen from 1,760 applicants, top finalists each earn $25,000 in scholarships and can nab between $40,000 and $250,000 if they are named in the top 10. This year’s virtual competition goes from March 10-17.
“Regeneron is definitely prestigious,” Licato said. “It feels great.”
Arlington Public Schools last had a senior — from Wakefield High School — make it to the finals in 1997. Washington-Liberty High School last had two students reach the final round in 1976, and have had four in total since 1942, said Society for Science spokeswoman Aparna Paul. Yorktown High School most recently had a finalist in 1996.
Licato credits the APS science staff with connecting him with extracurricular opportunities to present his work. His teachers also helped him work out the logistics of participating in science fairs and ordered materials he needed but could not obtain.
“The APS science department is awesome and has always been really supportive of everything I’ve done,” Licato said.
Licato said his area of research is a growing one, as more people become aware of the toxicity of these micropollutants. Many known pharmaceutical and personal care products (PPCPs) are toxic to aquatic organisms and perfluorinated alkyl substances (PFAs), found in non-stick and water-resistant coatings, can cause a host of diseases in humans, he said.
“The more we study, the more negative effects we find,” he said.
The benefit of his product is that it could be cheap and scalable because it could use the byproduct of coal fire plants, which normally sits in landfills, he said. It will need more testing and engineering work but Licato believes it has the potential to attract federal funding.
A Boy Scout and avid fisher, Licato has always been passionate about water quality and ecology. He won second place in the Earth and Environmental Sciences at the INTEL ISEF competition, also hosted by Society for Science, for his project removing an anti-diabetic medicine from wastewater.
That project introduced him to Thomas Huff, the Director of the Shared Research Instrumentation Facility at George Mason University, who specializes in researching river pollutants. Licato reached out to him because he needed to access a liquid chromatograph-tandem mass spectrometer.
At first, Huff was “highly skeptical,” but the then-sophomore won him over. He said Licato proved to be more adept with the machine than many senior undergraduate students.
Huff offered him an internship drawing and analyzing environmental samples at the Potomac Science Center in Woodbridge. He and a team of graduate researchers at George Mason University were determining the concentrations of PPCPs near wastewater treatment facilities for multiple grant projects.
Licato became a peer of the graduate student researchers, offering new ideas and mastering the software the team used, Huff said. He also developed methods of analyzing data that the other students and professors still use. The lab received a three-year contract to continue studying micropollutants.
“He was a consummate team member and morale booster,” the professor said. “He even taught tricks and tips to a full professor with 35 years of research experience.”
An “emergency utility repair” at Arlington’s sewage treatment plant led to a sewage release into Four Mile Run.
The sewage release happened this morning at the plant on S. Glebe Road. County officials are warning people to avoid the stream between S. Arlington Ridge Road and the Potomac.
“The public is advised to stay away from the affected water and to keep pets away until further notice,” Arlington County said in a press release. “Stream water can contain microorganisms that can make people sick, whether the stream is located in an urban area or in the middle of a forest. Even after the discharge is naturally flushed from the streams, the County’s normal precautions for safe use of streams apply.”
Crews are working to repair the unspecified issue at the plant. As a result of the work, a portion of S. Glebe Road is closed at S. Eads Street.
“An estimated completion time for the repair is unknown at this time,” the county said.
Separately, just before 9:15 a.m., a crash also blocked a lane of S. Glebe Road near S. Arlington Ridge Road, after an SUV reportedly careened into a utility pole.
Update at 1:30 p.m. — All lanes of S. Glebe Road have reopened, the county says.
Updated at 11:35 a.m. — The work on the county’s sewage plant has been postponed until next week, officials say.
UPDATE 11:15am – This repair work has been postponed. Any safe-but-perhaps-noticeable odor likely to be rescheduled for early next week. [Insert Redskins defense reference here.] https://t.co/N1wV5vJkpO

Earlier: The air near Arlington’s sewage plant is expected to be a bit more rank than usual
The county’s Dept. of Environmental Services announced yesterday that the plant near Crystal City was undergoing repair work on its odor control system, starting today (Tuesday). As a result “a sulfurous odor may be noticeable near the plant as air is vented out of manholes on both sides of South Glebe Road.”
Staff from the department provided a diagram (above) showing the location of the work and the odorous manholes, noting that the extra emissions are safe and not a health hazard.
The full announcement from DES is below.
Tomorrow through Friday, weather-permitting, crews at the County Water Pollution Control Plant will be repairing a duct connected to an odor control scrubber system that discharges cleaned air to the atmosphere. During the work, a sulfurous odor may be noticeable near the plant as air is vented out of manholes on both sides of South Glebe Road.
There is no health hazard posed by this work.
The photo [above] shows the scrubber buildings involved in the repairs as outlined and two small purple x’s indicating the manholes involved in venting.
Safety is always the plant staff’s No. 1 priority. Last year, the plant won the Virginia Water Environment Association’s Facility Safety Award.
Thank you for your patience and understanding.

People tend to flush and forget, but a plan approved by the County Board yesterday (Tuesday) could eventually result in the solid waste generated by Arlingtonians being deposited right back onto their lawns.
Fifteen years ago Arlington began a massive upgrade of the liquid side of its wastewater treatment facility — work that was finally completed several years ago at a cost of over a half billion dollars. Since then the solid side of the sewage plant has continue to degrade. Solid wastes are currently trucked away from the site five to six times each day. Instead, a new Solids Master Plan could transform that waste into soil enhancement for local yards and collect methane gas to be used in Arlington’s bus network.
“The solid site is now reaching the end of its natural life,” said Sarah McKinley, the president of the Columbia Heights Civic Association, who served as a community representative on the stakeholder committee. “We could replace it with current equipment or go to new technology that would really move us into the future.”
The new treatment is a three-phase process that will gradually replace equipment at the treatment center, with a total cost of $154.8 million spread out across those phases. The plan would require additional staff, but the cost is offset by reducing the number of truck trips from the site.
The new cleaning process would create two byproducts, a fertilizer-like biosolid that the plan says could be used by the public, the county, or commercial entities for soil treatment. Further processing — such as blending with soil or a “bulking agent” — would be required if the biosolid is to be locally distributed.
The other byproduct, a biogas compound, could be converted into compressed natural gas. The plan identifies the Arlington Transit bus fleet, conveniently parked across the street from the treatment facility, as a potential customer.
McKinley noted that there were concerns from residents living near the treatment site about pollution from the methane creation process and the routine gas flares from the treatment plant. However, she said added that committee believed the environmental and community benefits outweighed the concerns.
“I think it really moves us into the future,” said McKinley. “It makes sense. It’s a clean plan.”
The county is set to implement the new solid waste handling method in 2027.

Whether you are planning to watch the big game tomorrow or not (sorry Redskins fans), there’s one bowl we should all keep our eyes on: the toilet bowl.
The real evidence of Arlingtonians’ Super Bowl celebrating will be in the sewer pipes. The “Super Bowl flush” is the moment that thousands of toilets in Arlington all flush at the same time – halftime.
If all 184 million viewers flushed with a water efficient WaterSense toilet instead of an older model, over 400 million gallons of water could be saved! Instead of spending money on your water bill, you could spend it on your favorite beverage.
Using water = using energy. You may not think about it, but it takes a lot of energy to purify your water and then pump it to your home. After you flush, it also takes a significant amount of energy to get your waste to Arlington’s Water Pollution Control Plant, where even more energy is required to treat the wastewater.
Why does water use matter to you? Arlington’s water and sewer rates have increased significantly over the past 15 years. These costs mostly increased due to upgrades at the Water Pollution Control Plant to ensure that Arlington’s wastewater is cleaned to meet increasingly stringent standards.
Since energy and water are inextricably linked, using WaterSense toilets (faucets and showerheads, too) saves you money on your water bill, about $110 a year per toilet. This Super Bowl, when you flush, think about tackling that toilet, showerhead, or faucet upgrade by installing high-performance WaterSense fixtures. You’ll score some savings, even if your favorite team doesn’t win!

Democratic Challenger Launches Campaign — Small business owner and Planning Commission member Erik Gutshall formally launched his campaign to unseat Arlington County Board Chair Libby Garvey at last night’s Arlington County Democratic Committee meeting. Gutshall’s primary pitch to Democrats is “responsive, progressive leadership that you can trust.” Garvey upset many Democratic voters by endorsing independent Board member John Vihstadt and campaigning (successfully) to kill the Columbia Pike streetcar project.

Bikeshare By the Numbers — Critics of Capital Bikeshare are pointing to some system stats to suggest that it’s inefficient and serves a narrow segment of the population, though the reality is a bit more gray. Capital Bikeshare lost 30 cents on the dollar — rider revenue covers 70 percent of operating costs. But that’s not too shabby compared to other transit systems. In terms of operating costs per passenger-mile, Bikeshare is between Metrorail and Metrobus. Critics also point out that 84 percent of Bikeshare members are white while the District’s population is only 44 percent white (and Arlington’s population is 64 percent white). [Daily Signal]
DESIGNArlington Winners Revealed — The 11 winners of the annual DESIGNArlington awards for architectural and landscape projects have been announced. Among the projects receiving a “Merit Award” is the somewhat controversial sewage plant fence art project entitled “Ripple.” [Arlington County]

An assortment of pipes, wrenches, wheels and pink balls have been attached to the fence separating the Four Mile Run trail from the county’s sewage plant.
These items are part of an art installation by Dutch artist Tejo Remy and his design partner Rene Veenhuizen, who are known for their use of everyday objects to create works of art. The installation, which runs along the fence of the Water Pollution Control Plant on the 3400 block of S. Glebe Road, was completed in the middle of September, said Jim Byers, a spokesman for Arlington Cultural Affairs.
The display runs the length of the sewage plant, transitioning from a sea of pink balls and flat, blue objects to orange wheels and then a series of neon green wrenches and baby blue pipes. The piece starts with a lone pink ball.
“Remy and Veenhuizen’s design ethos stems from a strong industrial design background and building awareness about our connection to the environment,” Arlington Public Arts said in a press release. “Their innovative concept consists of more than 800 linear feet of brightly colored ‘widgets’ that reference the importance of microorganisms in the plant’s treatment processes and shaped fence panels overlaid on the existing fence to create a moiré effect reflecting the movement of water.”
The artwork is part of series of restorations and enhancements being made to the Four Mile Run area, which include work on bike trails and a new pedestrian-cyclist bridge. A ribbon cutting ceremony will be held once all projects are complete, Byers said.
The County Board approved the project in 2012, and $350,000 was allotted for the fence display, which included a $30,000 contingency fund. The project has stayed within that budget, Byers said
“Funding for this Contract is included in the approved $568 million budget for the Master Plan 2001 upgrade and expansion project at the Department of Environmental Services Water Pollution Control Plant,” he said. “The total cost of the fence enhancement project is 0.061 percent of the total of the upgrade and expansion project at the Department of Environmental Services Water Pollution Control Plant.”
(Updated at 1:45 p.m.) Tejo Remy, an artist for the Netherlands whose work has been featured in the Museum of Modern Art (MoMA) in New York City, is designing a fence for the plant that filters Arlington’s sewage.
The fence surrounds the Water Pollution Control Plant, on the 3400 block of S. Glebe Road, and it will be designed in Remy and design partner Rene Veenhuizen’s style of reusing common objects to create engaging works of art.
“The design-duo’s ethos stems from a strong industrial design background, reusing existing resources rather than consuming new materials, and building awareness about our connection to the environment,” Arlington Cultural Affairs spokesman Jim Byers said. “Remy and Veenhuizen have developed and will implement a compelling, innovative design concept which will serve as a unifying element within the Four Mile Run area, while creating distinct enhancements for the fence at the Water Pollution Control Plant.”
The project is expected in 2015, Byers said. It was approved by the Arlington County Board in April 2012.
Some of Remy’s noted work includes a “chest of drawers” displayed at MoMA and a chair made of rags. He spoke briefly about the fence project this week at an exhibition on Dutch design at the Netherlands embassy in D.C.
