The Paint Exchange Program is a free service to both drop-off and shop for paint. Residents can bring quality new or used paint to the Washington County Landfill to participate in the Paint Exchange Program. The paint needs to be water-based, latex house paint in cans that are more than a quarter full. It needs to be in reusable condition—within 2 years of being opened. If it does not meet these criteria, the paint can be disposed of at the biannual Household Hazardous Waste Collection Day or dried out and removed with your regular garbage.
