CTV: High lead levels in soil leave St. Boniface residents with questions
Some residents in St. Boniface may hold off planting gardens this spring.
University of Manitoba scientist Francis Zvomuya said some homes in the neighbourhood have tested positive for high lead levels in the soil, exceeding the national guideline.
“I don’t know what kind of affect it’s having on us,” said Teresa Cwik, a resident whose property had a result of more than 160 mg/kg from soil taken in 2017. She received a letter in April.
Zvomuya said his team collected more than 150 samples from yards and letters were sent to homeowners who surpassed the 140 milligrams per kilograms safety threshold, administered by the Canadian Council of Ministers of the Environment.
“Anything above the guideline, you have to be very careful how you used that,” Zvomuya said.
