After pulling more than 37 tons of trash from the Potomac and Anacostia rivers, the Capital River Relief project will conclude its massive volunteer cleanup effort with a final push this weekend. And in its last few days, the effort is getting some help from local sports and television celebrities.

Today at 1 p.m., “Survivor” stars Ethan Zohn and Jenna Morasca and D.C. United’s Bryan Namoff and Josh Gros will join Washington Capitals hockey player Trent Whitfield at a cleanup celebration at the Washington Channel Pier 4 on the Southwest waterfront.

The backdrop for the event will be the Capitol River Relief’s 140-foot barge, which is docked in the Potomac and has been piled high with trash collected from the two rivers — including some 2,800 bags of trash, 746 tires,12 shopping carts and one fake mannequin hand.

Refreshments will be served and the event is open to the public. The pier is located at Sixth and Water streets Southwest. For more information, call (202) 414-0773.

Ceremony Will Honor Iranian Hostages

On the 24th anniversary of the failed rescue attempt of 53 hostages held in Iran, the White House Commission on Remembrance will hold a wreath-laying ceremony on Sunday at Arlington National Cemetery to honor the American servicemen who died in that effort.

The event, which will take place at the Iran Rescue Mission Memorial Plaque, will honor Air Force Maj. Richard Bakke, Maj. Harold Lewis Jr., Tech. Sgt. Joel Mayo, Capt. Lyn McIntosh and Capt. Charles McMillan, and Marine Corps Sgt. John Harvey, Cpl. George Holmes Jr. and Staff Sgt. Dewey Johnson.

Ambassador Bruce Laingen, who was held hostage in Iran, will be on hand for the ceremony as will members of Special Operations Forces.

The plaque is located in Section 46 of the cemetery, and the event will begin at 12:15 p.m.
