Hu-Mar Chemicals

This former pesticide/herbicide production facility near Palacios, Matagorda County is in the feasibility study phase of the state Superfund program.

Site Summary

The Hu-Mar Chemicals Inc. site is located on the northern outskirts of Palacios, on McGlothlin Road, between 4th and 12th Street, west of State Highway 35, in Matagorda County, Texas. The 18-acre property was used for the production of pesticides and herbicides from 1976 to 1979.

During operations, the facility was the subject of numerous complaints. Production ceased and the site was closed in 1980, when the state denied renewal of the permit and the facility shut down. The state monitored removal actions by Hu-Mar Chemicals Inc., which included disposal of 190 drums of chemicals and demolition and removal of all contaminated structures. In 1985, on-site surface impoundments were filled in to grade and vegetated. The sludge from the pesticide manufacturing process was mixed with available site soil and used to bring the impoundments up to grade. A 1999 review of the remaining contaminants at the site documented hazardous substances from the pesticide production in the groundwater.

Superfund Registry and Investigation

In January 2000 the TCEQ proposed the site to the state Superfund registry. The remedial investigation began in June 2000 and the feasibility study began in October 2008.

Current Status

The site is currently undergoing a feasibility study to develop and analyze potential remedial action alternatives.
