Sand Mines and the Toxins They Produce in Local Water

Toxic residual acrylamides will result from the flocculation procedures that are part of processing of sand. This may contaminate all water that leaves the sand mine processing plant. We don't know where the millions of gallons of processing water Unimin plans to use will go.  Is it down into the ground or will it be piped somewhere?  Obviously the residual acrylamides should be monitored in the surface and soil water after Unimin processes it.
