Frac Sand Mining in IA, w/Regional map of Jordon Sandstone Thickness - including MN

Introduction to a Huge Issue for Iowa

With newly located data, it can now be stated with certainty, that all citizens who value Iowa's rich landscapes and small remaining patches of wildlife habitat, will need to pay very close attention to what industrial strength strip mining for frac sand does to the land surface, and to what fracking does to subsurface resources including essential groundwater aquifers where more than 90% of Iowans obtain their drinking water.

There are no rules or regulations at the state level, nor within any county that we are aware of, which address: 1.) Test drilling deep into vital groundwater aquifers (Jordan and St. Peter Sandstone Formations); 2.) Removing entire landscapes during the strip mining process for frac sand; 3.) Fracking (hydraulic fracturing) of vital underground aquifers; 4.) Frac sand processing facilities that traditionally use a million gallons of water per day of operation; 5.) Transporting frac sand on small to large roads and highways; and 6.) Health concerns stemming from such new issues as carginogenic fugitive silica sand dust, spillage of chemicals directly into exposed groundwater aquifers, and other as yet unidentified issues.

Until now we (in Allamakee and Winneshiek Counties) thought we were essentially alone in seeking to prevent the destructiveness of frac sand mining (as Clayton County had already capitulated to the whims of these miners at a grandfathered in mine).  But with the data I will distribute tonight, it will become obvious that scores of county governments and the state legislature will have to become directly involved in entirely new ways of protecting the health of Iowans, our state's natural resource base, and the quality of life we cherish.

Please scroll to the bottom of this page for quick and obvious visual lessons on this topic.

This is the first of three brief emails.  Each covers specific aspects of this issue.

Thank you.

THE MAP near the bottom of this page reveals WAY MORE FRAC SAND in IOWA than had been expected before.  And thus, a lot more danger than previously realized!!

Hydraulic fracturing is typically done in the horizontal portion of the well to stimulate a flow of gas from the shale. This well configuration is used in shale plays of the United States.

Many of the rock units that are currently being mined for frac sand are also aquifers. This makes ground water research publications, such as the ground water atlas series of the United States Geological Survey, valuable prospecting documents for determining the presence, thickness and structure of sandstone rock units. This map is from the Ground Water Atlas of the United States for Iowa, Michigan, Minnesota and Wisconsin. It shows the geographic extent and thickness of the Jordan Sandstone in Minnesota and Iowa. Similar maps have been published in this series for other sandstone rock units and other geographic areas
