The COVID-19 testing system has been overwhelmed by the Omicron variant, making it impossible to know how many people are infected. Monitoring for the novel coronavirus in wastewater could help fill the gap, says Rob Delatolla, a professor of civil engineering at the University of Ottawa and one of dozens of researchers across Canada that have been developing and using the technique. "I think it just became that much more valuable," he said.
Opinion: High gains but very low risks for reintroducing fluoride in Calgary's water
You don’t have to be in the health field to appreciate the overwhelming evidence that supports the benefits of adding fluoride into public drinking water.
