Oshawa, Ontario residents have noticed a suspicious substance leaking into their community. Development next to the former landfill almost didn't happen because city planners worried about this very possibility.
"Sarah Ross likes to walk her dog near Harmony Valley Park, but lately the Oshawa resident has been more cautious, after noticing an unusual rust-coloured substance staining the ground.
The liquid is oozing from the side of a seemingly inconspicuous hill, which is actually a decommissioned landfill site.
"I'm really concerned about what it is and whether any monitoring is going on," said Ms. Ross, a master's student in environmental studies. "A lot of people probably don't even realize there's a landfill there because it just looks like a hill. They're walking their dogs in the area and they should know whether there are any risks."
Brent Frew, who recently moved into the nearby neighbourhood, is also concerned.
"It looks like orange goo; it's kind of disgusting," he said. "It's the kind of thing that makes you wonder if it's OK for you to walk around there with your kids."
The landfill sits near the corner of Harmony Road North and Rossland Road East, with Harmony Valley Park on one side and a large residential subdivision on the other.
The site was formerly owned by Industrial Disposal Oshawa Limited (IDOL), and operated as a landfill from 1957 to 1980, when it was sealed."
