The safety and health of people living in the project area is the most important thing we can do on the Muskrat Falls Project. Our team is focused on understanding methylmercury in the lower Churchill River system, particularly downstream of Muskrat Falls.

The project team has been working closely with independent technical experts and consultants from across the country to better understand this complex topic, and years of research and data have been collected in the local area to help inform decisions made about the project. We are committed to continue monitoring after construction is complete and as long as necessary to help ensure the health of people in the area is protected.

Methylmercury Monitoring (Water & Sediment)

Monitoring for methylmercury in water and sediment is currently taking place in various locations in the lower Churchill River area. You can learn more about this program and view data results in the links below.

In October 2016, Nalcor engaged Amec Foster Wheeler to undertake water and sediment sampling. This program includes baseline, impoundment and post-impoundment sampling of water and sediment at 11 locations from upstream of the future Muskrat Falls reservoir to Rigolet. Background information about this program is available in the links below.

As per the Water Quality Monitoring Plan, our teams collect water samples on a regular basis and the raw data collected can be found on the Provincial Government Environment and Climate Change page.
