Montgomery County health officials partially lifted advisories Tuesday on fishing, boating and other recreation in the Potomac River, days after utility officials completed emergency repairs on the ruptured pipe that spewed several hundred million gallons of raw sewage into the water earlier this year.

The Montgomery County Department of Health and Human Services said Tuesday that recreation in the Potomac at Lock 8, about a half-mile downriver from the rupture site, is safe, according to a news release from the Maryland Department of Health.

Health advisories remain in place closer to the spill site.

The announcement comes after other health and environmental agencies lifted advisories in recent weeks as impacts have dissipated from the mid-January pipe rupture, which created one of the largest sewage spills in the country’s history.

The Potomac Interceptor, a large 70-year-old pipe that collects sewage from Washington, D.C.’s western suburbs, collapsed Jan. 19 at Cabin John, Maryland, sending at least 243 million gallons of waste into the Potomac River.

Levels of E. coli and other dangerous bacteria spiked in the river after the spill, but monitoring since by the Maryland Department of the Environment has shown declines downstream from the site.

Montgomery County health advisories remain in place for the land in the drainage area of the spill and the waters closest to the spill site — portions of the river within 200 feet of Swainson Island or 200 feet of the Maryland shoreline between the island and Lock 8.

Within several days of the rupture, DC Water, the capital-area utility that owns and operates the Potomac Interceptor, stemmed overflows into the river by diverting sewage into the historic Chesapeake and Ohio Canal.

DC Water hasn’t reported overflows into the river since Super Bowl Sunday. On Saturday, the utility announced the completion of emergency repairs to the interceptor following 55 days of work.

There have been no reported illnesses from the spill in Maryland, Health Secretary Meena Seshamani said in a statement Tuesday.

The District of Columbia lifted its recreation advisory for the Potomac on March 2, and Prince George’s and Charles counties lifted advisories downstream three days later.

Testing about 60 miles downstream also prompted Maryland to lift a precautionary closure of shellfish harvesting on the Potomac, though state officials remain concerned about the spill’s damage to perceptions of Chesapeake Bay seafood.

Swimming in the Potomac River in the D.C. area remains prohibited under policies dating back to the early 1970s.
