Do not throw the paint cans away or pour them into a city or storm drain either- they can easily leak or leech into the water supply or contaminate the ground. Check with your local city municipality for a safe place to dispose of paint- there are plenty of facilities that accept all types of household chemicals and paints for safe disposal or even recycling. Some hardware stores or paint stores may also have this information. For cleaning up after painting, follow the directions on the side of the paint can.
