Methylmercury Monitoring in the Muskrat Falls Reservoir, Churchill River and Lake Melville

Initial results from methylmercury monitoring

The current data collected as part of the Provincial Government’s Methylmercury Monitoring Plan is available below:

The initial data collected under the plan represents the establishment of a baseline for methylmercury and related parameters that can be compared with future monitoring results.

Updates will be provided on this site as sample analysis results become available.

Methylmercury Monitoring Plan

Monitoring for methylmercury in the Lower Churchill River area is currently ongoing as outlined in the Methylmercury Monitoring Plan Word Icon (10 MB).

The plan involves the thorough monitoring of the water quality of the Muskrat Falls Reservoir, Churchill River downstream to the eastern portion of Lake Melville and involves the assessment of changes in the level of methylmercury in water and sediment due to the creation of the reservoir. The plan builds on water quality monitoring that is already conducted by the Department of Municipal Affairs and Environment. The plan also augments methylmercury monitoring in biota (the animal and plant life) that is being conducted as part of Nalcor’s Aquatic Environmental Effects Monitoring Plan.
