Superfund Site: STEWCO, INC.
Superfund Site Profile
The Stewco, Inc. site is located in Waskom, Texas. A tanker-truck terminal and truck-washing facility operated at the site from the early 1970s until 1983. The site consisted of two locations about a mile apart, referred to as Location 1 and Location 2. Location 1 is a half-acre plot that included a maintenance shop with fueling facilities, a truck tank-washing facility, and two backfilled and capped evaporation ponds that received wastewater from the tank-washing operation. Location 2 consisted of a third pond that received wastewater conveyed by truck from the evaporation ponds at Location 1. Waste disposal practices contaminated soil, sludges and groundwater. Following cleanup, EPA took the site off the Superfund program’s National Priorities List (NPL) in October 1995.
