A plan that will map out at least three strategies to clean up the the plumes of contamination in and around the area of the Salina Regional Airport is underway.
“There’s a vast number of options on the table,” said Martha Tasker, City of Salina Utilites Director.
Tasker joined in the KSAL Morning News with an update from the frontlines of battling Salina’s underground pollution problem left behind when the military vacated the former Schilling Air Force Base.
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.”
Tasker added that two positive discoveries during the investigation over the past two years has been that the plume is moving at a slower pace than anticipated – and no harmful vapor has been found.
“We’ve done vapor intrusion in 60 to 70 buildings out there on the airport site and some residential sites and have found nothing that forces us into some type of mediation there. So that’s really good news,” Tasker said.
A feasibility plan should be finalized by the end of this year. By August or September 0f 2017 a cleanup plan will be proposed.
