  • The Newton, IA Landfill: A Smooth Operation

    The Newton, IA landfill sta rted out as an old strip mine in 1945. When it first was created, trash was dumped at the site and whenever it was needed, the garbage was set on fire and pushed into the old strip mine. As the rules have changed throughout the years, the dump was transitioned into a sanitary landfill in the late 1960s. However, at that time the trash would still pile up and would not ...
