San Angelo Electric Service Company (SESCO)

This former electrical transformer service, building, and repair facility in San Angelo, Tom Green County is being addressed under the State Superfund Program.

Site Background

The San Angelo Electric Service Company (SESCO) site (the site) is located on six acres in a residential area of northeastern San Angelo at 926 Pulliam Street. The company had been at the site since 1932 when it was founded as a motor magneto and starter repair company. Around 1946, the company transitioned its operations to building, repairing, and servicing electrical transformers. Spilled PCB (polychlorinated byphenyls) insulating oil from the transformer work was found in the soil and the underlying water. The PCB contamination had apparently entered the water by way of several unprotected wells on the property near the transformer work areas. Currently the site is bordered by residential property on the west and north. Light commercial/small businesses make up the east and northeast borders. On the south side, Pulliam Street separates the site from the San Jacinto Elementary School property. In 2003, San Angelo Electric Service Company (SESCO) did not respond to requests to remove contaminated soil from nearby residences. The state removed the contaminated soil from the nearby residences and the school soccer field, and installed several monitor wells.
