A contractor for the State Route 520 bridge project has paid $60,000 to the Department of Ecology and agreed to develop internal training materials as part of an agreement to settle an earlier environmental penalty.

Ecology fined Kiewit General, A Joint Venture, $90,000 in October 2015 for failing to properly decommission 15 groundwater monitoring wells at a construction site in Aberdeen, which put groundwater at risk of contamination.

“We take groundwater contamination threats seriously,” says Mike Gallagher, section manager for Ecology’s Water Resources program. “It’s unfortunate that Kiewit failed to take the proper steps to remove these wells, but we’re confident that moving forward the company’s employees will be trained to properly decommission wells.”

In addition to the $60,000 payment, Kiewit agreed to prepare internal educational materials and an environmental program manual addressing water and monitoring wells, and steps employees are to take if one is found during a construction project.

The company has one year to implement the changes to its employee training program.
