Contamination Cleanup Project Progressing
KSAL Staff - April 22, 2016 11:38 am
Officials offered an update Friday morning on contamination in and around the area of the Salina Regional Airport.
At issue is contamination, things like solvents that have seeped into the ground, left behind when the federal government vacated the former Schilling Air Force Base. The area is now the Salina Regional Airport. The main concern is two large underground plumes of contamination, one in the north part of the Airport Industrial Area, and another on the south end. A large plume of the solvent trichloroethylene, or TCE, is in the groundwater and soil. TCE at the time was used as an industrial solvent and has since been classified as a human carcinogen.
The Dragun Corporation has been working on a remedial investigation since June of 2014. Some highlights of the investigation include:
- 362 soil borings
- 258 temporary monitoring wells installed
- 70 permanent monitoring wells installed
- 1,627 soil, groundwater, and air samples tested
- 13,637 feet drilled
Officials said that there is no imminent threat of the contamination getting into the city water supply, and that currently it “does not pose any current significant risk to anyone.”
A feasibility plan should be finalized by the end of this year. By August or September 0f 2017 a cleanup plan will be proposed. There are several solutions that could be considered:
- Cleaning up the source of the contamination by removing the mass.
- Stopping the movement of the plume.
- Reducing the intensity of the concentration of the plume.
Once a cleanup plan is approved, local officials will go back to court to meditate with the federal government funding.
