Water Treatment Plant Eyed For Former Gold Mining District

Colorado, United States


Client Colorado Department of Public Health & Environment
Industries Water, Resources
Services Biological Sciences, Groundwater, Surface Water/Sediments, /Hydrogeology

Assignment:
A water treatment facility is planned on the site of a historic gold mining district in the State of Colorado, which has long been a US Environmental Protection Agency (EPA) Superfund site. This is due to a legacy of contaminated mine waste impacting surface water after the mining ceased.

The water at the site comes mainly from overflows from old drainage tunnels and surface water impacted from contacting contaminated materials. These tunnels effectively drain an extensive network of old abandoned underground mine workings.

Surface water will be captured in a collection system, while some that seeps into the groundwater may be collected separately and combined with the other surface water and diverted to the new treatment plant, which will be located less than one mile (1.6 km) away.

Our Role:
For this water treatment project, Golder is acting as the primary architect/engineering consultant and were directly responsible for all process, piping, equipment, and instrumentation and controls design. We will also provide construction and commissioning support services when the facility is built.

As part of our work, we completed bench testing in our Denver water treatment laboratory, plus a field pilot plant trial to verify expected process performance and to develop design criteria.

This project is due to be on the construction funding list for consideration by the US EPA. Several studies have been done to see whether a treatment facility may help to re-establish fish populations in the area.
