Tar Sands Nasty Little Secret

I’m sure oil executives will swim in the ponds to prove they are safe,

The industry estimates were way lower than the actual measurements, apparently because they did not include any escape of PAHs from tailings ponds, which are engineered dyke and dam systems built near mining operations in the oil sands to collect the water, sand, clay and residual oil left over from processing.

Until now, they were not expected to be a source of pollution.

PAHs are dangerous chemicals created in the burning of fossil fuels, and some are considered cancer-causing. They can also coat meats and other foods that are char-grilled.
