After nearly four years, the Central Coast Water Board is preparing to treat the source of water contamination near the San Luis Obispo County Airport.

The Central Coast water Board conducted four investigations starting in 2016 to find the source of trichloroethylene, or TCE, pollution in groundwater in the Buckley Road area near the San Luis Obispo County Airport, and the airport property itself.

The investigations included the sampling of domestic groundwater wells in the area and a collection of groundwater data from other well sampling programs that get reported to the county. This information allowed crews from the Water Board to conclude that the TCE in the Buckley Road area originates from 4665 Thread Lane.

The Senior Engineering Geologist for the California Water Board says, “The good news is we have concluded that the 4665 Thread Lane property is the source and we are going ahead with the requiring the replacement water which residents want and need as well as completing investigation and remediation of the TCE.”

The Central Coast Water Board prepared three solutions to fix the TCE contamination and presented them to the public Tuesday night.

The first would be the replacement of water for affected water owners. The second is the completion of the TCE investigation to refine where TCE pollution exists, and the third is remediation of the TCE pollution.

Officials say any solution will still take multiple years to implement.
