Oakdale Dump
The Oakdale Dump is an Environmental Protection Agency Superfund site located in Oakdale, Minnesota, and comprises three non-contiguous properties that were used for dumping from the late 1940s until the 1950s by the 3M corporation. The properties are named the Abresch, Brockman, and Eberle sites for their respective property owners at the time of disposal activities. The Abresch site is the largest of the three properties at about 55 acres. The Brockman site is located immediately southwest of the Abresch site and encompasses 5 acres. The Eberle site is located roughly 2,500 feet north of the Abresch site and encompasses 2 acres.
The Minnesota Pollution Control Agency (MPCA) investigated the three properties in 1980. Analysis of waste samples indicated that a variety of hazardous substances, particularly volatile organic compounds (VOCs), had been disposed in trenches at the Abresch and Brockman sites. Soil sampling at the Eberle site revealed a small amount of heavy metal contaminants.
The U.S. Environmental Protection Agency (EPA) placed the Oakdale Dump site on the Superfund National Priorities List on September 8, 1983.

A variety of hazardous substances, including VOCs such as isopropyl ether (IPE) and benzene, were disposed at the three sites. Soil sampling at the Eberle site revealed minimal heavy metals contamination. Analysis of residential well water revealed that nine shallow wells were contaminated with hazardous substances.
