After the expiration of an 18 month moratorium, Allamakee County has adopted rules that will regulate silica sand mining in the area.

Researchers at the University of Iowa have received a $125,000 federal grant to study the effects of frack sand mining on air quality.

The rise in hydraulic fracturing in the US and Canada has created demand for silica sand, used in the fracking process. There’s currently just one major frack sand mine in Iowa’s Clayton County. But parts of northeast Iowa are rich in these sand deposits.

Northeast Iowa is known for the big, scenic hills that dot the Mississippi River Valley and beyond.  Many of those hills contain sandstone. They can be used in hydraulic fracturing for oil and gas.

But some residents are concerned that more sand mining would harm the area’s environment.

Iowa Public Radio’s Sarah McCammon looks at the current state of “frac” sand mining in Iowa…and the potential for more.

You’ve probably heard about controversies over the environmental effects of hydraulic fracturing – the technique known as “fracking.” There’s no oil or gas fracking in Iowa…but the increasing use of the technique is affecting the state. It’s creating a market for finely-grained silica sand from northeast Iowa.

And some residents of the area are in conflict over the future of frac sand mining.

Controversy over so-called “frack” sand mining is heating up in northeast Iowa. A community meeting Wednesday evening in Decorah will focus on concerns about the possibility of mining development in Winneshiek County.

Fine sand can be used in the hydraulic fracturing process known as “fracking.” The technique is used to remove natural gas and oil from deep underground. There’s not any oil or gas fracking in Iowa right now – but there is a sand mine in northeast Iowa’s Clayton County, which is shipping frack sand out of state.
