EPA Superfund Program: MOSS-AMERICAN CO., INC. (KERR-MCGEE OIL CO.), MILWAUKEE, WI

Superfund Site Profile

The 88-acre Moss-American Co., Inc. (Kerr-McGee Oil Co.) site is located in Milwaukee, Wisconsin. In 1921, the T.J. Moss Tie Company started running a wood-preserving facility west of the Little Menomonee River in Milwaukee. The plant reportedly treated wooden railroad ties, poles and fence posts with creosote, a preservative that consists of a mixture of numerous chemical compounds derived from coal tar, and No. 6 fuel oil. For a time, the Moss facility discharged wastes to settling ponds that discharged to the river. Production stopped in 1976. Facility operations contaminated river sediment and site soil, groundwater and surface water with hazardous chemicals. Following construction of the site’s remedy, groundwater treatment is ongoing.
