The Washington Aqueduct, which supplies Arlington with its drinking water, will be making the annual disinfectant switch from chloramine to chlorine from Monday, March 7 through Monday, May 2.
The switch is intended as a “spring cleaning” for the pipes that supply water to Arlington, D.C. and part of Fairfax County. From an Arlington County press release:
Arlington’s safe and dependable drinking water may taste slightly different next week as the regional supply system undergoes its annual spring cleaning.
Crews at the Washington Aqueduct will begin the temporary disinfectant switch from chloramine to chlorine on Monday, March 7. The biological safety process, routine for many systems across the United States, will continue through Monday, May 2.
During the cleaning, Arlington’s Water, Sewer, Streets Bureau will continually monitor the output for safe chlorine levels as well as conduct system-wide flushing to enhance water quality.
The Aqueduct also adds a corrosion control inhibitor during the switch to prevent the potential release of lead in system pipes throughout the region. Extensive research in Arlington has failed to turn up any lead service lines or lead pipes inside homes.
Running the cold water tap for about two minutes, using water filters and letting water sit in a container in the refrigerator are generally effective for removing chlorine taste and odor.
Customers who take special precautions to remove chloramine from tap water should continue such methods during the temporary switch to chlorine. As always, those with special concerns should consult their health care provider.
Operated by the U.S. Army Corps of Engineers, the Washington Aqueduct is the wholesale supplier for Arlington, the District of Columbia and northeastern Fairfax.
Arlington’s drinking water meets all of the safety standards established by the federal Environmental Protection Agency and Virginia Department of Health. The bureau’s latest annual water quality report will be released in May.
Arlington’s Water, Sewer, Streets Bureau offers a staff presentation on the water system to any schools or community groups that request one.

The change is a result of the region’s annual switch in water disinfectant, from chloramine to chlorine, according to the Department of Environmental Services. The change, which helps clean the area’s water distribution system, will last until May 4.
“Local water authorities recommend running the cold water tap for approximately two minutes and refrigerating tap water to reduce the chlorine taste and odor,” DES spokeswoman Jessica Baxter said in a press release. “Water filters are also effective for reducing chlorine taste and odor.”
The county, in its frequently asked question page about the disinfectant switch, says if you don’t want to refrigerate your tap water, run the tap for 5-10 minutes before drinking to remove the chlorine taste and smell.
The change is not made at Arlington’s water treatment facility, it’s made by the Washington Aqueduct, which supplies all the drinking water to D.C., Arlington and Fairfax County from the Potomac River.
The Washington Aqueduct will be making a temporary switch from the disinfectant chloramine to chlorine from Monday, March 17 to April 28.
“The annual switch in water disinfection is part of a routine program to clean and maintain drinking water systems in the District of Columbia, Arlington County and the northeastern portion of Fairfax County,” according to a press release. “During the temporary switch to chlorine, local water authorities will also conduct system-wide flushing to enhance water quality. This program is a common practice for many U.S. water systems that use chloramine during the majority of the year.”
“Individuals may notice a slight change in the taste and smell of their drinking water,” the press release continued. “Local water authorities recommend running the cold water tap for approximately two minutes and refrigerating tap water to reduce the chlorine taste and odor. Water filters are also effective.”
Arlington County Board Chairman Jay Fisette, who last year launched a “personal crusade” against bottled water, will debate a representative of the bottled water industry this weekend.
Fisette and Chris Hogan, Vice President of Communications for the Alexandria-based International Bottled Water Association, will speak at the Arlington Committee of 100’s monthly dinner meeting.
The debate, which is being held at Marymount University (2807 N. Glebe Road) will begin at 8:00 p.m. on Wednesday, Jan 8. An RSVP is required by Jan. 5.
From the event’s Facebook page:
In 2009, the Arlington County Board passed a resolution banning the use of taxpayer funds to purchase single use, bottled water – with a very few exceptions. That resolution spoke to the environmental cost of producing, transporting and disposing of these bottles. While that may have reduced their use at county sponsored functions, many of us still use single use bottled water. Incoming Board Chairman Jay Fisette has begun a crusade to reduce the use of single use plastic water bottles. At our January meeting we will address the questions related to this initiative. What are the advantages of single use bottled water? What are the effects on the environment of the way we dispose of the empty bottles? Are there alternatives that provide the same or similar advantages?
Arlington County water department employees and representatives from the Natural Resources Defense Council are also expected to attend.

It’s that time of year when Sherlock Shad (pictured left) begins appearing more frequently in Arlington neighborhoods. But the county needs help attaching the storm drain markers bearing his likeness.
Arlington marks many of its more than 10,000 storm drains as a reminder that anything going into a drain heads directly to local streams that flow into the Potomac River. The river is the source of tap water for Arlington and much of the D.C. metro area.
Nothing should be dumped into storm drains, per Arlington County Code Section 26-5, which reads: “…it shall be unlawful for any person to discharge directly or indirectly into the storm sewer system or state waters, any substance likely, in the opinion of the County Manager, to have an adverse effect on the storm sewer system or state waters.”
Arlington partners with the neighboring jurisdictions of Fairfax County and Alexandria to all order the same style of markers. Ordering the markers in bulk helps each jurisdiction keep costs down. The costs vary each year based on how many markers need to be attached.
Arlington County Department of Environmental Services Stormwater Outreach Specialist Jen McDonnell said in addition to affixing the markers to currently unmarked drains, volunteers replace some markers that are damaged or have come loose from the pavement.
“Whether it’s snow removal or new construction, these markers do come off with time,” said McDonnell. “Not only are they [volunteers] affixing the markers, but they can tell me which streets need new markers or what is unmarked.”
The markers list different streams depending on which neighborhood they are placed in. Some of the waterways include Lubber Run, Four Mile Run, and Gulf Branch.
The glue used to attach the markers to the pavement does not work in cold, wet conditions. Therefore, the markers only can be applied on dry days during the late spring, summer and fall.
Nearly anyone can volunteer to help out, including adults, scout groups or middle school and high school students wishing to fulfill service hours. Volunteers receive all the materials necessary to attach the markers. Once finished with the task, volunteers report which drains they have marked so the locations can be entered into an electronic database.
“This project allows the citizens to be involved and clues them in to all the storm drains. It makes them think about if there are things in the street, where it all goes,” McDonnell said. “It’s a great, easy program that people can get out and do whenever they have time for it.”
Anyone who would like to volunteer to affix the markers in their neighborhood should contact Jen McDonnell at [email protected] or 703-228-3042. Residents can also contact her to report a storm drain in need of a new marker.
(Updated at 10:25 a.m.) If you think this year’s annual spring water system flush is giving Arlington’s water a stronger than usual taste or smell, you’re right — and officials say the weather is actually playing a factor.
Just like every year since 2000, there are about six weeks in the spring when Arlington’s water is purified with chlorine instead of chloramine. In 2011, the chlorine level was downgraded from 3.7 parts per million to 3.0 parts per million because of a number of resident and staff concerns.
This year, however, some people have mentioned what they believe to be a stronger taste or smell to the water. Although the number of formal complaints so far hasn’t exceeded other years, ARLnow.com readers started a forum thread on the topic. One reader posted: “It’s overpowering and sickening. We’ve been clearing out the shelves of those 3-gallon jugs of water at Giant.”
Although the amount of chlorine has not changed, the cold weather appears to accentuate the taste and smell of chlorine.
“It’s a theory. Basically the warmer temperatures will generally use up a little more of the chlorine as it goes through the system,” said Dave Hundelt with Arlington County Department of Environmental Services. “We think, looking back, the reason we had so many complaints in 2011 was [the flush] started on February 1, when the temperatures were colder, and the chlorine was more noticeable. This year, we started a week earlier, during the third week instead of the last week of March. That combined with the temperatures in the region. They appear to be colder in the past few weeks than it was in March of 2012.”
Hundelt says as temperatures increase, the water warms up and the chlorine should be less noticeable. The temperature shift necessary to create a perceptible change in smell and taste is relatively small. Analysts are finding a stronger smell and taste when water temperatures are at or below 10 degrees Celsius (50 degrees Farenheit). Comparatively, water temperatures were around 7-10 degrees Celsius (about 44-50 degrees Farenheit) in Feburary 2011 when complaints poured in, but were at a balmy 16 degrees Celcius (about 60 degree Farenheit) last April.
Arlington’s water is purchased wholesale from the Washington Aqueduct, so much of the region experiences the same water conditions.
In addition to the chlorine change, each of the the county’s 3,500 fire hydrants will be opened for a short period to make sure the entire water system gets adequately flushed. That is too large a job to finish when the chloramine conversion ends on April 29, so residents may continue to see hydrants flushed into the month of May.
Anyone with major concerns about the water system, such as water main breaks, should call 703-228-6555 to report issues. More information about the switch from chloramine to chlorine can be found on the county’s website.
Water Change Underway — The annual, temporary switch from chloramine to chlorine as the tap water disinfectant is beginning, as part of a flush of the water system.

Ballston Garage to Get $3.5 Million in Repairs — The Arlington County Board on Saturday awarded a contract of up to $3.5 million for structural repairs to the eighth level of the Ballston Public Parking Garage. The eighth level of the garage was added in 2006, but the concrete was found to be deficient for long-term use — prompting claims that resulted in the county settling with the original contractor for an undisclosed sum. Kettler Capitals Iceplex, which is located on the top level of the garage, will remain open during the construction, which is expected to take 5-6 months. [Sun Gazette]

Update at 4:40 p.m. — Chlorinated water leaking from a water main near Shirlington has seeped into Four Mile Run and killed “dozens” of fish, an Arlington County official told ARLnow.com this afternoon.
We first reported the leak near 2400 S. Walter Reed Drive this morning, after Claremont and Fairlington residents reported widespread low water pressure in the area. Now we’re told that the leak — in a 12-inch pipe — has resulted in a significant fish kill.
From Arlington Department of Environmental Services spokeswoman Shannon Whalen McDaniel:
Residents may notice dead fish in portions of Four Mile Run downstream of the break due to the chlorinated water being released. This water is not harmful to humans or pets, but unfortunately resulted in a fish kill. Residents should follow the County’s normal precautions for safe use of urban streams.
McDaniel said repairs on the water main are expected to continue into tomorrow. Residents may continue to experience low water pressure but “no one is expected to be without water,” she said.
Updated at 2:55 p.m. — This article has been updated here.
Low water pressure has been reported in the Claremont and Fairlington areas.
The water pressure issue is the result of a leak in a 12-inch pipe located near 2400 S. Walter Reed Drive, according to Arlington Department of Environmental Services spokeswoman Shannon Whalen McDaniel.
“Crews are now trying to isolate the leak for repair,” Whalen McDaniel told ARLnow.com. “Some areas may be out of water during the period of repair.”
Via Twitter, residents told us the low water pressure started last night (Tuesday). No word yet on when service may be restored.
You may not have even realized it, but your water meter will get a makeover soon, if it hasn’t already. The county is about half finished with its efforts to install new automated meter reading (AMR) systems on residential buildings.
The new meters allow employees to easily gather water use information without physically having to access meter boxes. They are equipped with a radio transmitter than sends each meter reading to an employee who slowly drives through the neighborhoods.
“The meters tend to lose accuracy as they age, so one of the benefits is the increased accuracy of the reading,” said county engineer Mary Strawn.
AMR will reduce errors now that employees will not have to manually enter meter numbers. It’s also viewed as a safety measure, considering workers won’t have to scramble in some places with hard to reach meters.
Residents can expect to see fewer “estimated reads” on their bills, due to the efficiency of the new meters. Previously, if county workers were unable to find a meter due to factors like snow accumulation, they would estimate a customer’s monthly water use.
The county began installing AMR equipment on commercial and multi-family residences in 2007. Now, the project has moved on to the 30,000 single family residences. Workers are about halfway through that task, and hope to finish by early 2013.
Notifications are being sent out to residents before work on their meters begins. Installation only takes about five minutes, so most people probably won’t even notice that work has been done.
Sometimes, after the meter has been upgraded, residents may temporarily notice a burst of air or rust colored water. This is not harmful, and briefly running the cold water should clear this up.
On Monday the taste of your tap water may be changing as the Washington Aqueduct conducts its annual “spring cleaning.”
Residents may notice a distinct “chlorine” taste and smell in the water for the next seven weeks. Local water authorities issued the following press release about the change:
From March 26 through May 7, 2012, the disinfectant in drinking water will temporarily switch from chloramine to chlorine.
The annual switch in water disinfection is part of a routine program to clean and maintain water distribution systems in the District of Columbia, Arlington County and Falls Church. During the temporary switch to chlorine, local water authorities will also conduct system-wide flushing to enhance water quality. This program is standard practice for many U.S. water systems that use chloramine during the majority of the year.
The Washington Aqueduct is the organization responsible for treating drinking water — including water disinfection — for the District of Columbia, Arlington County, and Falls Church, Virginia. Local water authorities are responsible for monitoring drinking water to ensure chlorine levels continue to meet safe target levels.
Individuals and business owners who take special precautions to remove chloramine from tap water, such as dialysis centers, medical facilities and aquatic pet owners, should continue to take the same precautions during the temporary switch to chlorine. Most methods for removing chloramine from tap water are effective in removing chlorine. Individuals with special health concerns should consult with a health care provider on the use of tap water.
During this time, individuals may notice a change in the taste and smell of their drinking water. Local water authorities recommend running the cold water tap for approximately two minutes and refrigerating cold tap water for a few hours to reduce taste and odor. Water filters are also effective in reducing chlorine taste and odor.
The massive upgrade of Arlington’s Water Pollution Control Plant, which is almost finished, is apparently already causing environmental benefits in the Chesapeake Bay. Plus, it has created a new source of revenue for the County.
Tests show the $568 million expansion and modernization of the WPCP has reduced the amount of harmful nitrogen it deposits into the Chesapeake Bay. That means the County will receive tradable credits that can be sold through the state’s Nutrient Credit Exchange Program. Earlier this week, the County Board voted to participate in the program, and also approved Arlington’s membership in the Virginia Nutrient Credit Exchange Association.
“The County has made a huge investment in expanding and upgrading the Water Pollution Control Plant, and it is great to see that – even before the upgrade is completed – the effort is producing significant benefits for the Bay and creating a new source of revenue for Arlington,” said County Board Chair Mary Hynes. “This expansion is proving to be a worthwhile investment for our County and the region.”
The County could receive between $22,000 and $410,000 each year for its utility fund by participating in the exchange. Because it’s a new member, Arlington would have to wait the required three to five years before receiving money for its credits. There is an annual membership fee of $3,125 for the program.
The WPCP treats 30 million gallons of wastewater each day. Most of its renovations are slated to be finished this summer. A refurbishment of the fence around the facility will start this spring and end in the fall.
Did you know that Arlington’s drinking water actually comes from the District of Columbia? And that when the county’s first drinking water system was completed residents held a big parade with elaborate floats in Clarendon?
Those are two of the interesting historical facts recently brought to light in an article on drinking water in the county’s Ballston Pond Blog. That article, written by county employee Jen McDonnell, is reprinted here with permission.
Arlington has three, separate pipe systems running underground that handle our three types of water – drinking (potable), wastewater, and stormwater. But there was a time in Arlington (not that long ago) when these pipe systems were not in place. In 1900, wells were the drinking water source for Arlingtonians, and outhouses and septic tanks “managed” the wastewater.
In 1926, the Arlington Board of Supervisors funded a study to devise a plan to bring a drinking water system to Arlington. The study findings recommended that Arlington connect to the Army Corp of Engineers-operated drinking water filtration plant that pulled water from the Potomac River for the District of Columbia’s residents. In 1926, Congress passed two acts that made this proposed plan possible. The first act authorized the sale of water from the federal supply to Arlington and the second act approved the connection of Arlington County to the federal supply. Virginia’s General Assembly then approved bonds to fund this major project. A water main was constructed from the Dalecarlia Plant in Washington D.C., across Chain Bridge, and then along Glebe Road. Infrastructure including pumps and pumping stations were installed and initially 340 homes were connected. Construction cost $636,110.
When the new drinking water system became operational, a big parade with elaborate floats was held in Clarendon. Arlingtonians wore buttons saying, “YES We Have Water.” The new, easy access to water encouraged change and growth in Arlington. In the post-WWI era, housing became denser around the available water connections. Easy water access encouraged the use of larger quantities of water, and increased the quantities of wastewater produced. While the drinking water system has been significantly expanded since then, Arlington still gets its drinking water from the Potomac River and the Dalecarlia Plant today.
An equally interesting history of the county’s wastewater system has also been posted on the Ballston Pond Blog.
