Study finds Iowa groundwater is extracted at unsustainable rate

February 7, 2017

A recent study found the groundwater in Iowa’s Jordan Aquifer to be much older than previously known, and scientists say that could have implications for water use in the state.


Marion to drill new well in anticipation of possible water shortages

November 28, 2016

The Marion Water Department plans to drill a new well this spring to supplement the Jordan aquifer, which now supplies the city with the majority of its water. The city enlisted Mike Gannon of the Iowa Geological Survey to find other sustainable water sources for the city.


Why we need to test water to improve quality

November 25, 2016

As the November 20th article, “Can Iowa improve its water quality if it can’t agree how to measure success?” pointed out, there is not an immediate cause-effect relationship between a practice implementation and water quality improvement. However, that is hardly an argument for favoring one approach over the other.

Researchers were intrigued by the strange shale sample, which contained some extraordinary fossils. Liu was the first to suggest that Decorah could have been the site of a meteorite impact—basically, a crater. Scientists have not only identified and confirmed the Decorah Impact Structure, but Liu and his team also found an astonishing collection of fossils there.

May 25, 2016

As Iowa farmers have planted more acres of corn to meet the demand driven by the corn-based ethanol industry, many models predicted that nitrate concentrations in Iowa streams would increase accordingly. However, recent IIHR research based on water monitoring casts doubt on these predictions.


Fossils Wave Hello from Iowa Past

April 6th, 2016

 

Imagine Iowa 385 million years ago. Imagine it submerged underwater and surrounded by a coral reef. That is what Iowa looked like in that era — the same time period in which fossils dug up by construction crews would have been living creatures.

A discovery in Iowa City has given scientists a window into the past. Construction crews doing work in the area found fossils dating back to a time when Iowa was covered by water.“It’s a whole history in the ground beneath our feet of how Iowa and the world has changed over time,” said Tiffany Adrain, collections manager at the University of Iowa Paleontology Repository.

Fossils found at University of Iowa Construction Site

While digging up for the future some Iowa City construction workers found a piece of the past. The University of Iowa’s College of ENgineering is expanding the Seamans Center. While digging in February, construction workers found some fossils.


 Fossils found in Iowa City evidence of ancient ocean covering the state

March 29th, 2016

Iowa may be far from the beach, but experts say that likely wasn’t the case 385 million years ago. Geologists like Ryan Clark say fossils dug up during Iowa City construction reveal the whole state may have once been underwater.


UI Construction Uncovers Fossils

March 28th, 2016

A discovery in Iowa City is giving scientists a window into the past. Construction crews doing work on a university building found some fascinating fossils of ancient coral reefs and the animals that live in it. Fossils are like a time capsule created millions of years before humans roamed the earth.
