D.C.’s annual spring household hazardous waste drop-off event will be from 9 a.m. to 3 p.m. Saturday.

The D.C. Department of Public Works is asking residents to bring items such as old cleaning and gardening chemicals, small quantities of gasoline, pesticides and poisons, acids, varnish, oil-based paints, solvents, aerosols and wood preservatives to the Carter Barron Amphitheatre parking lot at 16th and Kennedy streets Northwest.

This service is free and open to all District residents.

Other items such as spent batteries of all kinds, roofing tar, chemistry sets, automotive fluids and asbestos floor tiles can be brought to the collection site for environmentally safe disposal or recycling.

A professional hazardous waste contractor will remove materials from the residents’ vehicles and a licensed hauler will take the waste to an Environmental Protection Agency-approved facility for processing.

Residents may bring televisions and audio equipment, computers, computer parts and computer components for end-of-life disposal or recycling. All computer monitors and TV screens must be intact and not cracked, punctured or shattered.

Items that will not be accepted during the collection day include ammunition, audio speakers, explosives, bulk trash, wooden TV consoles, propane tanks, microwave ovens and other appliances, as well as radioactive or biologically active wastes.

Lincoln Assassination Topic of Walking Tour

An award-winning author and historian will conduct four two-hour Lincoln assassination walking tours this weekend.

Anthony Pitch, a recipient of the Maryland Historical Society’s annual book prize for “The Burning of Washington: The British Invasion of 1814,” will lead the tours. He is currently working on a book about Lincoln’s assassination.

Tours depart at 10 a.m. and 2 p.m. Saturday and Sunday, starting in Lafayette Square and concluding nine blocks east, in Chinatown. The anecdotal walk will pass Ford’s Theater, the house where Lincoln died, the home of the man who struggled with the assassin and the boarding house where conspirators plotted the murder, among other sites.

This same tour was recently aired on C-SPAN. Proceeds from the event will go to the Tourette Syndrome Association of Greater Washington.

The tour is recommended for adults and children 10 years of age and older. Advance tickets are required and can be purchased for $15 apiece by calling (877) 295-2148.
