MINNEAPOLIS (Oct. 2, 2012) — More than 50 people gathered Monday to protest frac sand mining outside a conference on the silica sand resources of Minnesota and Wisconsin.
“This is total destruction,” said Kathleen Bibus of Red Wing, Minn. “We know the chemicals they use will contaminate the groundwater. We know the dust causes silicosis.”
Some communities are looking to try to ban shipments of SAND on the railways - much like the nuclear waste bans.
