Sand forum features environmental experts
Hydraulic fracturing for oil and natural gas is not occurring in Minnesota, but one substance that's vital to the procedure is located in the state.
"Nationally, silica sand isn't found in very many places," Heather Arends, industrial mineral supervisor with the Minnesota Department of Natural Resources, explained at a local discussion this week. "The source of silica sand is very isolated to Minnesota, Wisconsin."
Some silica sand can also be found in Iowa and Illinois.
