Contractors have been deployed to Sudbury's Ramsey Lake to clean up a residential oil spill that migrated to the shoreline on Jan. 17. The Ontario Ministry of the Environment, Conservation and Parks estimates around 812 litres of home heating fuel spilled onto the ground from a storage tank at a property on Gennings Street, near the lake. While Ramsey Lake is the main source of the city's drinking water, ministry spokesperson Gary Wheeler said there is only a low risk to the thousands of people who get their municipal drinking water from the lake.
