Layfield Well Positioned to Help Mitigate Contamination from Oilsands Tailing Ponds Contaminating Groundwater

Environmental Watchdog Report says Alberta Oilsands Tailings Ponds are Tainting Groundwater

VIC EPA Sets Limits on PFOS Level for Contaminated Soil Disposal and Landfill Leachate (Declassified and Redacted)
The maximum leachable PFOS+PFHxS (perfluorooctanesulfonic acid and perfluorohexane sulfonic acid) concentration in spoil is likely to be approximately 0.7 micrograms per litre (μg/L).
The proposed liner for the containment cell was found, given a 0.7 μg/L PFOS or perfluorooctanoic acid ( PFOA) leachate, to be protective of the beneficial uses of the underlying groundwater within
the 100-year model time.
