Camdenton TCE Sites Fact Sheet (posted 10/20/17)

Brief Overview

Modine Manufacturing Co. is conducting investigations of TCE releases at the 221 Sunset Drive facility as ordered by the department. Modine's earlier facilty investigations focused on soil contamination at the site. Through advances in science and an increased understanding of potential health effects related to vapor intrusion, the investigations expanded in December 2015 to collect samples of the indoor air inside the manufacturing building and nearby homes for vapor intrusion.

Hamilton-Sundstrand, parent company of former Sundstrand Tubular Products, is addressing related groundwater contamination issues with the Hulett Lagoon and Mulberry Well under an official agreement with the department. A water treatment system was installed as a temporary measure to keep the TCE plume contained and not spread to other city or private wells. The system aerates the TCE out of the water and into the open air.

The department's Permits section is managing the former manufacturing building site and the department's Superfund section is managing the Hulett Lagoon and Mulberry Well sites. Both department sections are working closely on the coordination of the investigation and the corrective action/remedial activities.

The department has received citizens concerns regarding the Dawson Metal Products Camdenton Facility #2 (DMPF #2) located at 1225 US Highway 54. It has been reported that TCE was disposed of “out the back door” into the environment during temporary operations of Dawson Metal Products after a fire at the original Sunset Drive facility location. As part of this investigation, Superfund staff are looking for any detailed and supported information about this claim and the sludge disposal reports listed below.

The second investigation is focused on the Camdenton Sludge Disposal Area site. In 1989, the sludge from the closed Hulett Lagoon was land applied in a field north of Forbes Road at the end of the runway at the Camdenton Memorial Airport. The department received new information from a citizen that two additional sludge disposal areas might exist. Superfund staff is looking for any detailed and supported information about this claim.
