Excellent.
I would like to ask Dr. Barker to interpret something for me, if I may. In his written presentation there is a statement regarding “investigating the potential for process-affected groundwater to leach toxic trace metals from the sand aquifers and so mobilize the metals towards surface water bodies”. He further says, “To date, while metals such as iron and manganese appear to be mobilized, the toxic trace metals, including arsenic, do not appear to be enhanced in the plumes”.
So your studies have indicated that toxic trace metals are not transported by groundwater to surface water in the areas you've studied. Am I getting that right, or is it something else?
