Projects that involve dumped soil near groundwater are highly risky and there are lots of provincial rules about preventing soil from getting in them, says retired water resources engineer Ian McLaurin. "Groundwater is what we drink," McLaurin, who has his own water well at his home in Durham Region and serves as volunteer advisor for upset residents, told CBC Toronto. "We pull it straight out of the ground and we drink that stuff totally untreated, and so that's why we're concerned about soil going into water," he said.
It is very risky in terms of groundwater contamination. As the motion currently stands there is no groundwater quality or quantity study. There is no ecological assessment.
