The Lakehead Regional Conservation Authority is embarking on improving water quality in Rosslyn. Spokesperson Bob Hartley says a recent water quality report shows septic systems in the community are potential threats to the two municipal wells. Hartley adds homeowners will need to have their septic systems inspected. A series of public meetings on the water quality report will be held next week. Thunder Bay's water source Lake Superior came through with flying colours with no potential threats to water quality.
