March 4, 2015, Vancouver – Mining company Teck Trail Operations will begin construction on a $40-million ground water treatment plant as part of the company's overall ground water remediation plan. 

 

The remediation plan was submitted to Environment Canada in 2012, and is designed to address ground water affected by the site’s historical activities, the company said in a news release.

 

The ground water is not used for drinking water and studies conducted to date have found that the fish populations in the river are not affected by the ground water and the water quality of the river meets drinking water standards, the release said.

 

The remediation plan includes interception of the affected ground water using a series of wells, two of which have already been constructed. The ground water will be conveyed to the treatment plant for treatment prior to discharge into the Columbia River. The discharged water will meet all regulatory requirements, the company said.

 

The affected ground water contains variable concentrations of ammonia, sulphate and some metals, and is located directly beneath Trail Operations, under the Columbia River and under a portion of East Trail. The company said it believes the substances originated from historical operations and storage of materials prior to the 1980s.

 

Three monitoring wells will also be installed this spring to assist in delineation of the area of affected ground water and enable us to monitor the efficiency of the remediation system.
