Fresno Municipal Sanitary Landfill opened in 1935 in Fresno, California, was the first modern landfill in the U.S., pioneering the use of trenching, compacting, and daily burial to combat rodent and debris problems.[2] It became a model for other landfills around the country, and one of the longest-lived. The landfill was operated by the City of Fresno until it closed in 1989. At that time, the landfill had reached the size of 145 acres (0.59 km2).[3] It was declared a National Historic Landmark in 2001.[2]
In 1983, the California Department of Health Services was conducting tests and found that the site contained methane and vinyl chloride gases that were penetrating into the surrounding areas around the landfill. These tests also concluded that contaminants were being found in private ground-water wells around the landfill. On June 24, 1988, the site was proposed as a superfund site and was finalized on the NPL list on October 10, 1989.[3]
