Kim Reynolds. Bedrock aquifers are underground rock formations that can store water. The layers of limestone, dolomite and sandstone that make up Iowa's aquifers range from 5,200 feet deep in ...

Giant new oil and gas wells that require astonishing volumes of water to fracture bedrock are threatening America’s fragile aquifers. Increasingly complex oil wells are sweeping across Texas ...

Wells drilled down into the sand and bedrock aquifers would produce artesian conditions, where the groundwater is under sufficient pressure—fed by geometry or elevation differences—to cause ...

Nearly all — 90 percent — of the water used for ethanol production comes from bedrock aquifers, which take hundreds to thousands of years to recharge, the Sierra Club reported. Iowa also has ...

The deep sandstone aquifer receives little natural recharge ... aquifer , an underground layer that is made up of permeable bedrock — Abrams predicts that wells in the southwest suburbs ...

Researchers have discovered an aquifer that was much bigger than they ever expected. “It is all locked up in fractures in the bedrock but it’s what we call active groundwater, meaning it’s ...

Aquifers of sand and gravel allow water to pass through quickly and can be easily contaminated by polluted recharge water. In fractured bedrock, or karst areas, water moves between cracks and channels ...

Synthetic chemicals that persist indefinitely in the environment have been detected in the water of several deep wells in parts of Iowa with porous bedrock, according to the Iowa Department of ...

The report states that Iowa has two types of aquifers - alluvial and bedrock aquifers; alluvial aquifers are near the surface and recharge relatively quickly with regular precipitation ...

Mapping deep underground aquifers that are below the bedrock is really expensive and is not part of this project. The funding to start mapping shallow aquifers is included in a budget bill that ...
