Lose the lawn: D.C. offers free plants to replace turf or pavement

To help limit polluting stormwater runoff, D.C.’s Department of the Environment is offering city residents free edible plants and pollinator plants to replace their turf and pavement.

DOE also has scheduled two free workshops on landscape-maintenance techniques ─ including the use of rain barrels, permeable pavement, and rain gardens ─ to capture stormwater before it enters streams and rivers.

Registration deadline for both the plant give-away and landscape-maintenance workshops is Wednesday, March 26.

For each 100 square feet of turf or pavement that residents agree to replace, they will be given topsoil and 15 shrubs or perennials or one fruit or nut tree.

“The removal of turf and pavement allows for the revegetation with trees and plants, which capture rainwater and allow it to soak into ground,” DOE states. “Plants also grow roots through the soils, making the soil spongy so that in time, even more water can infiltrate.”

Plants available are: raspberry, blackberry, dewberry, blueberry, strawberry, lemon balm, oregano, sage, rosemary, thyme, lavender, mint, fennel, asparagus, mallow, coneflower, and bachelors buttons.

Trees available are: shadberry, apple, fig, persimmon, peach, and pecan.

Residents who register for the plant-giveaway must submit a photo of the turf or pavement they intend to remove, followed by a second photo showing its subsequent removal in preparation for planting. The second photo is due on April 26, one week before the plant pickup, which is scheduled for 10 a.m. to noon on May 3 at the Anacostia Park skate pavilion, 1900 Anacostia Drive S.E. Free topsoil also will be available for participants to pick up from three area retailers between April 11 and May 11.

The plant-giveaway is funded by a grant from the Environmental Protection Agency under the Clean Water Act.

DOE’s one-hour landscape-maintenance workshops for city residents will be at 10:30 a.m. on April 19 at the Takoma Park Recreation Center, 300 Van Buren St. N.W., and at 10:30 a.m. on May 3 at the Anacostia Park skate pavilion.

Potomac Watershed Trash Summit set for Oct. 18

Field trips showcasing efforts to reduce litter in the Washington area will highlight the 8th annual Potomac Watershed Trash Summit on Oct. 18 in Washington.

The trash summit, to be held at the University of the District of Columbia’s David A. Clarke School of Law, also will feature an appearance by Jim Toomey, creator of the nationally syndicated cartoon “Sherman’s Lagoon.” Toomey is an advocate for taking steps to end marine litter.

The annual trash summit is organized by the Alice Ferguson Foundation and brings together citizens, public officials and youth leaders to collaborate on ways of eliminating litter from the Potomac River watershed.

Field trips scheduled as part of the summit are:

■ Communities in Action. A tour of on-the-ground efforts in Prince George’s County, Md., to implement the foundation’s Regional Litter Prevention Campaign, which relies on public education and awareness to change littering behavior. The tour will include a “trash free community” and litter hotspots.

■ Trapping and Tracking Trash. With a primary focus on the Anacostia River, the field trip will explore efforts to capture trash in the water and monitor what is left behind.

■ Composting: Big and Small. The tour will feature the University of Maryland’s multi-faceted composting program and the city of College Park’s yard waste composting program.

The field trips are scheduled for 8:30 a.m. to 12:30 p.m., with participants asked to bring their own trash-free lunch. Early registration is encouraged, as space on the field trips is limited. Afternoon sessions will be held from 1 p.m. to 4:45 p.m. at the law school.

A complete agenda of the summit is available at http://fergusonfoundation.org/wp-content/uploads/2013/08/Summit-2013-Brief-Agenda-FINAL-8-6-13.pdf.

The registration fee for the summit is $25. To register, go to the summit web site at http://fergusonfoundation.org/trash-free-potomac-watershed-initiative/potomac-watershed-trash-summit/.





Potomac sewage spill warning failed to reach D.C., Northern Virginia

By Wayne Savage


Utilities that draw drinking water from the Potomac River for Washington, D.C., and much of Northern Virginia received no official warning in mid-December as 3.5 million gallons of raw sewage spilled into the Monocacy River, a major Potomac tributary.

As public-works employees in Frederick, Md., scrambled to repair an electrical malfunction that crippled the city’s sewage-treatment plant on the evening of December 11, officials of the Maryland Department of the Environment placed urgent calls to the Rockville water-treatment plant and the Washington Suburban Sanitary Commission, the primary water utility for Montgomery and Prince George’s counties.

MDE’s calls warned Rockville and WSSC of the spill, which started at 7 p.m. and continued until 3 a.m. the following day. Frederick’s sewage-treatment plant discharges wastewater into Carroll Creek, some 500 feet above its confluence with the Monocacy River.

But official notification of the December 11 spill never crossed state lines to reach water utilities downstream in Virginia and the District of Columbia, as called for by a longstanding early-warning plan devised by jurisdictions in the Potomac River basin.

Under the early-warning plan ─ which is voluntary and not mandated by federal law ─ MDE should have notified the Interstate Commission on the Potomac River Basin. The ICPRB, in turn, is tasked with spreading the alarm to downstream water utilities so they can take mitigating action, if necessary, in response to contamination events. ICPRB’s role includes running a computer model to determine the times that contamination is likely to reach downstream water-intake pipes.

Potomac River watershed map

The Potomac River watershed covers four states and the District of Columbia.

Among the communities left in the dark on December 11 was Leesburg, Va., some 30 miles downstream from Frederick and the closest to the spill.

“I don’t have any documentation in my file that we got notified,” said Larry Taylor, manager of Leesburg’s water-treatment plant. He said, however, his file contains a printout of a story from the Frederick News-Post website.

Tom Jacobus, general manager of the Washington Aqueduct, said he and his staff were unaware of the Frederick sewage spill until contacted for this report.  The Washington Aqueduct, a division of the U.S. Army Corps of Engineers, supplies water for Washington, D.C., and Arlington County, Va.

Fairfax Water, which supplies water to a large swath of Northern Virginia, including Fairfax and Loudoun counties, also missed the warning.

“We do not have a record of being notified of that spill,” said Fairfax Water spokeswoman Jeanne Bailey. “I don’t believe we were aware of it.”


Multiple sewage pathogens

Raw sewage can contaminate water with bacteria, viruses, protozoa and parasitic worms that cause human disease, including “serious illnesses such as cholera, dysentery, infectious hepatitis, and gastroenteritis,” according to the U.S. Environmental Protection Agency. “Sensitive populations ─ children, the elderly, and those with weakened immune systems ─ are at a higher risk of illness.”

“In a serious spill, sometimes the [water] utility will need to take measures to avoid contaminating their intakes or change their treatment process,” said Cherie Schultz, director for CO-OP operations at the Interstate  Commission on the Potomac River Basin.

The ICPRB has developed models that estimate the time of travel and concentration of contaminants that enter the Potomac River, Jacobus said by email.

“This provides utilities with needed information about a wastewater treatment plant overflow and gives warning so that water treatment plant managers can assess the potential effect of that overflow on the treatment system,” Jacobus said. “These managers may decide that it is prudent to add more chlorine to neutralize the bacteria that are over and above the normal river conditions.”

Jacobus and officials of other downstream water utilities, including Leesburg and Fairfax, said the December spill posed no danger to public health. According to these officials, the sewage was so diluted by the time it reached their intake pipes that it required no change in the routine treatment of raw water taken from the Potomac.


State agency alerted

Frederick officials alerted the Maryland Department of the Environment within an hour after the spill started. But according to multiple sources, the state agency did not pass the word to the ICPRB, as called for by the region’s early-warning plan.

A statement released by MDE confirmed the agency notified WSSC and Rockville ─ the two nearest downstream water utilities in Maryland ─ but not the ICPRB. The MDE said it is “taking steps to address the communications issue” and has strengthened its emergency response procedures by improving its internal communications and by “reminding our staff that under our response plan they should directly contact ICPRB as soon as possible after any spill in the Potomac area.”

Carlton Haywood, director for program operations at the ICPRB, said employees of his agency didn’t learn of the spill until they read a newspaper report on the morning of December 13. That was some 36 hours after the spill started ─ too late for the downstream water utilities serving Virginia and the District of Columbia to take remedial action, had it been necessary.

ICPRB’s computer model showed that the leading edge of the sewage spill would have taken 17 hours to reach Leesburg, about 10 miles downstream from the Monocacy’s confluence with the Potomac, arriving at noon on December 12, with the peak concentration coming at 4 p.m..

After passing water intakes that supply Fairfax Water, the WSSC, and Rockville, the leading edge of the spill would have reached the Washington Aqueduct’s intake at Great Falls at 7 p.m., with the peak coming at midnight, according to the computer model.

Dilution of the sewage spill was aided by a relatively high level of water in the Potomac. At noon on December 12, the river was flowing at 31,300 cubic feet per second, or about 234,000 gallons per second, as measured by the U.S. Geological Survey at Little Falls, 10 miles below Great Falls. That flow rate was more than twice the historic average recorded for December 12 by the USGS.

Noting the Potomac’s high flow, Haywood said that by the time bacteria from the Frederick spill “got down to the Washington-area utilities, the concentrations were likely down to roughly the same as background levels, more or less.”

Similar assurances came from the downstream water utilities.

“In the Potomac River with a dilution factor there shouldn’t have been any problem,” said Taylor, manager of the Leesburg water-treatment plant.

Bailey, the Fairfax Water spokeswoman, said that given the distance the sewage spill traveled, it would not have impacted her utility. Fairfax Water’s two intakes are near the border of Loudoun and Fairfax counties, some 40 miles downstream from Frederick.

“We don’t feel that spill would have had any impact on our water supply or any treatment changes would be necessary,” Bailey said.


Maryland utilities notified

Officials at both Rockville and WSSC said the Maryland Department of the Environment notified those two water utilities of the sewage spill at 9 p.m. on December 11. MDE’s warning calls, however, did not include the Interstate Commission on the Potomac River Basin.

The WSSC found no need to raise chlorine levels in response to the spill, according to spokeswoman Lyn Riggins, who said the raw sewage “was diluted by billions of gallons of river water by the time it got to us.”

“We kept an extra eye out,” Riggins said, “but there was nothing out of the ordinary.”

Marylou Berg, communications manager for the Rockville city manager’s office, said that routine, around-the-clock testing showed no difference after the spill.

“We continually monitor the chlorine level leaving the plant … to get the water quality to the appropriate level,” Berg said. “The amount we needed to maintain the water quality didn’t have to go up.”

Berg described the sewage spill as “really not much of an event for us.”

“Certainly the river was contaminated by this extra sewage,” Jacobus said in an interview, “but the river is always contaminated.”  He said raw river water is assumed to be non-potable, and water-treatment plants are designed to make it potable according to EPA standards.

Based on the ICPRB’s computer model of the Frederick spill, Jacobus said there was no need to change the Washington Aqueduct’s treatment process because “the effect of the bacteria would have been incrementally negligible at the intake.” (The aqueduct’s Great Falls intake is some 50 miles south of Frederick.)

“We have a very sound bacterial-disinfection process that can handle what comes to us from the river,” Jacobus said.

Jacobus suggested that a chemical spill, especially petroleum, would be more problematic because water-treatment plants “were not fundamentally designed to handle” such contamination. In 1993, a ruptured pipeline sent 407,000 gallons of diesel fuel into Sugarland Run, a Potomac River tributary near Reston, Va., forcing Fairfax County to shut down its Potomac water-treatment plant for more than a week.


Federal law silent

on interstate warning

Frederick officials were required, as a condition of their sewage-treatment plant operating permit, to notify the Maryland Department of the Environment of the sewage spill. But federal law does not mandate that notification include the ICPRB, which would have warned downstream water utilities of the incident.

“What [utilities] are not obligated to do is report to other agencies in other states, so that is the gap that ICPRB is trying to fill,” said Haywood, echoing a slogan that appears prominently on the ICPRB website: “Watersheds Cross Political Boundaries. That’s Why We’re Here.”

The ICPRB, however, is a non-regulatory body, and participation in its early-warning system by the Maryland Department of the Environment is voluntary.

Jacobus said the breakdown in the chain of notification was the first he knew of in his 16 years with the Washington Aqueduct. He called it “a uniquely rare event in my experience.”
