Take a look in the garage . . . . if there are old paint cans, old containers of turpentine, paint remover, or other unusable and possibly unstable household chemicals, the Sanitation Districts of Los Angeles will be hosting three local Household Hazardous Waste Roundups here in the South Bay this spring. Why wait? Place the old containers in a box, put the box in the trunk the night before the event and drop them off on April 28 in Hawthorne, May 5 in Rancho Palos Verdes, or June 16 in Torrance. Participants don’t even have to leave the car, just pull into the drive queue and pop the trunk. Check the calendar for locations and a list of what to leave home.
