Background

The South Minneapolis Residential Soil Contamination Site covers a roughly circular area with a radius of about three-quarters of a mile, centered on the intersection of Hiawatha Ave and 28th St in south Minneapolis. From 2004 to 2008, EPA cleaned up almost 200 properties with arsenic levels that posed an immediate threat to children. (Children are especially at risk to arsenic contaminated soil because they are more prone to getting the soil into their mouths.) From 2009 to 2011, EPA cleaned up almost 500 properties with lower, but still unsafe, levels of arsenic. This phase of the cleanup was supported by $20 million in Recovery Act funding provided to EPA.

The yards were contaminated by wind scattered arsenic from a pesticide formulation plant already cleaned up by the Minnesota Department of Agriculture (MDA) called the CMC Heartland Lite Yard. To reduce the risk from arsenic exposure, one foot of topsoil from affected residential yards was removed and replaced with clean soil. In some cases EPA removed more soil if testing showed deeper arsenic contamination. The contaminated soil was trucked to an off-site, licensed landfill for safe disposal. Soils used to backfill the yards was tested to make sure it was safe.

The CMC Heartland Lite Yard site (plant site) was located at the northwest corner of the intersection of Hiawatha Ave and 28th St. Several companies produced pesticides at the plant from 1938 to 1968. When arsenic was discovered at the plant site, health agencies suspected that the wind might have blown contaminated dust into nearby neighborhoods. Yards were sampled in all directions from the plant site.

More information about arsenic from the Agency for Toxic Substances and Disease Registry.
