Don't forget to include NORMs on the list.  We had detectable levels in Quebec but, not at concentrations of toxicological significance.  I would suspect the "list" will vary depending on the fracking agents used and the formation in question though.

Dear All
In preparation for the deluge of "fracking applications" anticipated now expoloraory licenses are being marketed for sale, I thought it might be helpful to regulators, planners and practitioners to prepare a definitive list of "Chemicals of Potential Concern" associated with fracking practices.

I would be grateful if those that known, could point me in the direction of a list(s) (I've seen a number of lists on US and Wikipedia type webpages) of fracking chemicals and more importantly their respective C4SL/GAC for soils, and health and ecological surface and ground-water screening standards.

I would anticipate that such a list would be used to set appropriate operational acceptance criteria, to inform post operational clean up, and determined suitability of the sites for future uses (and possible Part 2A determination), thereafter?

Best wishes,
