Monitoring Water Quality in the Elk Valley

We are conducting extensive studies and monitoring of water quality and aquatic health, which includes regular water quality sampling at more than 130 locations across the Elk Valley. To date, regional monitoring indicates that current levels of selenium and other substances are not impacting populations of fish or birds. Monitoring shows that selenium concentrations have been reduced downstream of our water treatment facilities at Line Creek and Elkview and we expect further significant reductions as the new Fording River facilities come online.

Sharing Monitoring Results

Teck is committed to being transparent with stakeholders as we implement the Elk Valley Water Quality Plan. We make data and results from ongoing water quality, aquatic and animal health research and monitoring undertaken as part of the Plan available, and we will continue to share those results going forward. This includes Annual Reports completed by an Environmental Monitoring Committee comprised of an independent scientist and representatives from the B.C. Government, Ktunaxa Nation Council, Interior Health Authority, and Teck. Monitoring reports related to the Elk Valley Water Quality Plan can be found below. 

Elk Valley Water Quality Plan Technical Reports

These reports are the result of ongoing research and monitoring of water quality and aquatic health as part of the Elk Valley Water Quality Plan. They were prepared by professional scientists and represent the knowledge developed since 2014 when the Plan was approved. The reports have been reviewed by the Environmental Monitoring Committee and shared with regulators and the Ktunaxa Nation. These reports are used to inform the ongoing implementation of the Elk Valley Water Quality Plan.

Overall, the report findings confirm that the targets established in the Elk Valley Water Quality Plan for selenium and other substances are appropriate and protective of aquatic life. The findings also indicate that concentrations of selenium and other substances are generally trending as expected. The concentrations are not affecting fish populations, but effects on some types of benthic invertebrates (certain types of mayflies) have been observed in specific downstream areas and studies are being undertaken to determine the cause.

2020 Regional Water Quality Model Update Report (March, 2020)

Teck developed the Regional Water Quality Model (RWQM) to examine how activities at its steelmaking coal mines in the Elk River watershed could affect water quality in the Elk River and Fording River. The RWQM is a tool used to simulate how historical, current, and future mining activities could affect the concentrations of water quality constituents of interest in the Fording River, Elk River, tributaries to these rivers (collectively referred to as the Elk Valley) located in and around Teck mine sites, and Koocanusa Reservoir. The RWQM is used to support local and regional water quality mitigation planning and to support water quality evaluations for mine water management and mine development applications.
 
Teck is required to update the RWQM every three years in accordance with Environmental Management Act and Mines Act permit requirements. There have been two updates to the RWQM since the first model was developed for the Elk Valley Water Quality Plan in 2014, with the most recent update being the 2020 RWQM. The 2020 RWQM was subjected to a rigorous review by the B.C. Ministry of Environment and Climate Change Strategy, the B.C. Ministry of Energy, Mines and Low Carbon Innovation and representatives of the Ktunaxa Nation Council.
 
The 2020 RWQM update is focused on modeling methods and does not include adjustments to the water quality mitigation plan and water quality projections included in the documentation do not represent expected future concentrations. The 2020 RWQM is based on an updated and improved conceptual model for constituent release and transport in the Elk Valley and is the tool that has been used to support the development of the 2022 Implementation Plan Adjustment, which is the third iteration of the water quality mitigation plan for the Order constituents (nitrate, selenium, sulphate and cadmium).
 
The documentation includes the main report and the following four supporting annex documents, which provide greater detail on the model inputs, methods and results:

Annex A: Geochemical Source Term Methods and Inputs for the 2020 Update of the Elk Valley Regional Water Quality Model
Annex B: 2020 RWQM Update: Hydrology Modelling – Set-up, Calibration and Future Projections Report
Annex C: 2020 RWQM Update: Water Quality Modelling Set-up and Calibration Report – Order Constituents

2020 Regional Water Quality Model Update Report (March, 2020)

Teck developed the Regional Water Quality Model (RWQM) to examine how activities at its steelmaking coal mines in the Elk River watershed could affect water quality in the Elk River and Fording River. The RWQM is a tool used to simulate how historical, current, and future mining activities could affect the concentrations of water quality constituents of interest in the Fording River, Elk River, tributaries to these rivers (collectively referred to as the Elk Valley) located in and around Teck mine sites, and Koocanusa Reservoir. The RWQM is used to support local and regional water quality mitigation planning and to support water quality evaluations for mine water management and mine development applications.
 
Teck is required to update the RWQM every three years in accordance with Environmental Management Act and Mines Act permit requirements. There have been two updates to the RWQM since the first model was developed for the Elk Valley Water Quality Plan in 2014, with the most recent update being the 2020 RWQM. The 2020 RWQM was subjected to a rigorous review by the B.C. Ministry of Environment and Climate Change Strategy, the B.C. Ministry of Energy, Mines and Low Carbon Innovation and representatives of the Ktunaxa Nation Council.
 
The 2020 RWQM update is focused on modeling methods and does not include adjustments to the water quality mitigation plan and water quality projections included in the documentation do not represent expected future concentrations. The 2020 RWQM is based on an updated and improved conceptual model for constituent release and transport in the Elk Valley and is the tool that has been used to support the development of the 2022 Implementation Plan Adjustment, which is the third iteration of the water quality mitigation plan for the Order constituents (nitrate, selenium, sulphate and cadmium).
 
The documentation includes the main report and the following four supporting annex documents, which provide greater detail on the model inputs, methods and results:

Annex A: Geochemical Source Term Methods and Inputs for the 2020 Update of the Elk Valley Regional Water Quality Model
Annex B: 2020 RWQM Update: Hydrology Modelling – Set-up, Calibration and Future Projections Report
Annex C: 2020 RWQM Update: Water Quality Modelling Set-up and Calibration Report – Order Constituents

Westslope Cutthroat Trout Fish Populations:Upper Fording River

As reported previously, monitoring conducted for Teck in the fall of 2019 found that the abundance of Westslope Cutthroat Trout (WCT) adults and sub-adults in the upper Fording River had declined significantly since previous sampling in fall 2017. 

Teck established an Evaluation of Cause team of external experts to investigate and report on the possible causes of the fish count decline. The Evaluation of Cause team found that the upper Fording River fish population decline happened in the winter of 2018/2019 and was caused by the interaction of extreme ice conditions (due to extreme prolonged cold air temperatures, seasonal winter low flows and low winter snowpack), sparse overwintering habitats and restrictive fish passage conditions during the preceding migration period in fall 2018. While some stressors such as cold weather are natural, mining development has altered the availability of overwintering habitats in portions of the river and exacerbated the challenges to fish passage through water use, channel widening and aggradation. The findings indicate water quality constituents, including selenium, were not a primary contributor to the decline. The final Evaluation of Cause Report and supporting technical reports can be found on this page.

Teck and the Evaluation of Cause team met regularly with the Ktunaxa Nation Council and government regulators to review findings and respond to questions during preparation of the report and their feedback has been reflected in the final materials.

Monitoring is ongoing and 2021 fish survey results indicate a positive trend in the WCT population. The 2021 snorkel surveys of the upper Fording River and select tributaries observed 796 WCT compared to 168 and 166 in 2019 and 2020 respectively. Of the 796 WCT observed, 364 were noted to be juveniles, indicating successful recruitment in the system. The study team is currently evaluating the data for the 2021 monitoring reports and once finalized will be publicly available in 2022.

Additionally, Teck is supporting recovery of the fish population and is working with government regulators and the Ktunaxa Nation Council to develop and implement a comprehensive fish recovery strategy. Since 2019, we have worked to rehabilitate approximately 40,000m2 of fish habitat along five kilometres of the upper Fording River and reconnected 14 kilometres of tributary habitat. This work included creating overwintering pool habitat, adding woody debris, improving fish passages and planting over 45,000 seedlings across 21 hectares to improve riparian areas, in addition to limiting water use during low-flow periods and increased monitoring.

Westslope Cutthroat Trout Fish Populations:Harmer Creek

In a separate watershed (which includes Harmer and Grave Creeks), results of WCT population monitoring indicated recruitment failures in 2018 and 2019 in Harmer Creek. In addition, monitoring indicated there was reduced recruitment in 2016 and 2017. Recruitment failure means there was a negligible number of individuals added to the population. The abundance of adult WCT in the Harmer Creek population has remained comparatively stable, throughout both the historic period and recent years. An Evaluation of Cause Team is working through available information to determine potential stressors that may have contributed to the recruitment failures.
