About $850,000 is being invested into the expansion. The work builds on the recent results of a pilot study in Halifax and Wolfville where the virus that causes COVID-19 was detected in wastewater. Now testing will be done at many more locations in the province. "We'll be open to the province to focus on what could be priority sites," said Dr. Graham Gagnon, the lead researcher of the project who is the director of the Dalhousie University Centre for Water Resource Studies.
