Methylmercury Monitoring Plan

Monitoring for methylmercury in the Lower Churchill River area is conducted as outlined in the Methylmercury Monitoring Plan pdf icon (2.65 MB).

The plan involves the thorough monitoring of the water quality of the Muskrat Falls Reservoir, portions of the Churchill River, Goose Bay, and 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.
