Varies research teams at the University of Iowa recently launched an interactive private well map for Iowa residents. Lead by CHEEC (The University of Iowa Center for Health Effects of Environmental Contamination), the Iowa Geological Survey and the UI Hydroinformatics Lab, the Iowa Well Forecasting System–otherwise known as the IWFoS–is a powerful tool for the public.

Users looking to build new wells can use the map to determine the new well site and the quality of the water in that area. By looking at the water quality data of existing wells adjacent to the potential new build, a safe location for a new source of water can be determined.

Thousands of Iowans relay on wells for their water. CHEEC director David Cwiertny estimates that roughly 60% of Iowans rely on groundwater, with about 300,000 Iowans relying on private wells specifically. While recent news about nitrate levels from agricultural fertilizers has been concentrated on Iowa’s rivers, Iowa’s wells suffer from contamination issues too, and the comprehensive data that IWFoS provides is vital for those looking to expand a town’s water resources.

Well forecasts–the details of well water quality and the locations of safe private wells–have been available through the Iowa Geological Survey for years, but these forecasts were generally only available during business hours. IWFoS is accessible 24/7 and uses IGS’s geological info for the well locations, combining this with datasets on well water quality from the Private Well Tracking System that the Iowa Department of Natural Resources manages.

Transparency with our water quality data is one of the best ways to ensure that safe natural resources are available for all Iowans, all the time.

Another round of flooding impacting southwest Iowa

People in Southwest Iowa suffered record-breaking flooding in mid-March thanks to the spring extreme rainfall and rapid snowmelt. Now, a second round of flooding is on the horizon, threatening those previously affected.

 The saturation of the soil, a large amount of rain and the river flow are once again causing road and highway closures, county evacuations and major floods warnings around the southwest part of the state. 

According to the National Weather Service, the Missouri River in Nebraska City measured approximately 22.5 feet, and it soon could reach critical stages of flooding. The Missouri River in Plattsmouth, Neb., was at 31.3 feet, and could soon reach the moderate flooding stage.

As rain continues to fall, residents from Mills County, Iowa, near the Missouri River, have been advised to evacuate the area for their own safety. In the meantime, almost 300 people have been under obligatory evacuation in the western portion of Fremont County.

The main concern of officials is not only the record-breaking rains and the rising river levels, but they are also concerned that the floods from early March, left the county with no protection against flooding, according to Iowa Public Radio.

These heavy rains have caused significant damage to the roads and interstates, the interstate highway 29 in Iowa and Missouri have closed for the second time due to the flooding; the first time was the flooding from early March, and now the road closes again after only two weeks of being repaired. Portions of highway 34 and highway 2 have also closed due to flooding. 

The traveler Information encourages divers to check 511ia.org or call 800-288-1047 if they have any questions before traveling through the Midwest. 

Experts advise people to stay cautious, and if they see roads with water over them, it’s best to turn around and find an alternate route, since it is impossible to guess how deep the water in the road could possibly be.

Monarch Butterflies Migrating to Iowa

Sthefany Nóbriga| May 8, 2019

 Researchers from Iowa State University predict that this spring Iowans will see the largest population of monarch butterflies in over a decade. 

The monarch butterflies migrate every winter to Canopy Forest in central Mexico. During the winter of 2013 to 2014, the monarch population plummeted, covering less than 2.5 acres of the forest, the lowest point of the population in the past two decades. This is partly because of the loss of summer breeding habitat and pesticide use. 

However, this past winter scientist noted Mexico’s most significant overwintering monarch population since 2007. Almost 200 million adult monarch butterflies were recorded, and now they are migrating up north.

According to the researchers from Iowa State University, the reason for the increase in the monarch population is due to mild winters in Mexico, and southern parts of the United States in comparison to other years. 

Scientists are hopeful and want to maintain the monarch population and preserve their numbers. But it is reported that there is a shortage of potential breeding habitats in Iowa to maintain a steady population. 

In order to maintain this population, there must be approximately 480,000 to 830,000 acres of habitat over the next 10 to 20 years according to Iowa Public Radio. 

If the weather stays favorable, Iowans will be seeing a large monarch population starting at the end of May or even early June. 

Iowa reacts to proposed EPA Clean Water Rule rollback

Regulation over streams on farmland is in dispute (flickr).

The Trump administration’s proposed rollback of the 2015 Clean Water Rule would reduce federal jurisdiction over wetlands, streams and other small water bodies on Iowa farmland. Some Iowans see the proposal, officially made in mid-December, as a win for farmers, while others see it as a hit to much needed water quality regulation in the state.

Since the start of his term, Pres. Trump has wanted to limit Obama’s 2015 Clean Water Rule, which more clearly defined “Waters of the United States” within the Clean Water Act of 1972. This increased the protected area by about 3 percent (according to an op-ed from Bloomberg News) by adding more streams and neighboring wetlands, ponds and impoundments into federal jurisdiction and reducing those waterbodies that could once be given/denied protection on a “case-by-case” basis.

The current administration proposes removing wetlands without clear surface connection to larger bodies of water from protection, as well as “ephemeral” streams that only flow with rainfall or snowmelt, about 18 percent of the country’s total streams. The proposal is now undergoing 60 days of public comment.

In November, the country already allowed Iowa to halt enforcement of the rule until disagreement over it was settled in court. Most farmers seem to want that allowance made permanent by the Clean Water Rule rollback. The Iowa Farm Bureau shared a statement of support in December after the EPA announced the proposed rollback, and called the Obama Era rule an “overreach.”

As Iowa Sen. Joni Ernst told reporters, “Iowa’s farmers, ranchers, manufacturers and small businesses can now breathe a sigh of relief knowing that going forward a tire track that collects rain water won’t be regulated by the federal government.”

Iowa has serious water quality issues, however, caused for the most part by runoff from farm fields containing harmful nutrients like nitrate and phosphorus. The state recognizes the importance of on-farm streams and wetlands in managing soil and water quality, and encourages the construction of buffers between crops and waterways to minimize runoff into streams or wetlands.

Curt Zingula, a Linn County farmer who uses a saturated buffer on his farm to protect a creek, told the Sioux City Journal he is proactive about water quality management, but thinks the Clean Water Rule “cast a shadow” over a landowner’s entire farm.

Others believe the rule was necessary, however, and think the proposed rollback will worsen Iowa’s water problem. A staff editorial in the Gazette called Ernst’s statements “hyperbole” and pushed for more focus on the water itself in the discussions surrounding the proposed rule change.

“If the Trump administration can’t explain how its definition will lead to cleaner water, and all of its related benefits, it should go back to the drawing board,” it reads. “Otherwise, it’s simply replaced Obama’s ‘overreach’ with a dereliction of duty to protect the nation’s waters for future generations.”

Iowa expects to get drenched

After its third-wettest September on record, Iowa can expect a rainy October, too. The DesMoines Register reported that 4 to 5 inches of rain are forecasted to fall over most of the state in next few days. For some localities, it’s already started.

Southwest Iowa may be hit the hardest. Forecasts there predict 6 or more inches of rain.

The rain is expected to fall almost endlessly at least into early next week. National Weather Service meteoroligst Brooke Hagenhoff told the Register that the widespread nature of the forecast will likely increase the rainfall’s impacts on rivers and low-lying areas.

Some parts of the state are already saturated. Despite a fairly dry start to the month, flood alerts have been active for parts of the Des Moines, Cedar and Iowa Rivers throughout this week thanks to late-September rains in northern Iowa. The Iowa Flood Information System gauged a major flood stage for the Wapsipinicon River at DeWitt as of Wednesday afternoon.

 

New climate predictions for Iowa

Eden DeWald | July 25th, 2018

Two professors from Iowa recently contributed an article to the Des Moines Register about new climate change predictions for the state of Iowa. Gene Tackle, an emeritus professor of agronomy at Iowa State University, and Jerry Schnoor, a professor of civil and environmental at the University of Iowa and co-director of the Center for Global and Regional Environmental Research at the University of Iowa, wrote about the serious effects that climate change will have for Iowans, and how Iowans are already being effected.

Schnoor and Tackle reference information from the from the Climate Science Special Report which is part of the National Climate Assessment Report. The report found that heat wave temperatures will increase to a range of 97-102 degrees by 2050. Currently, heat wave temperatures fall in a range of  90-95 degrees. These temperatures have serious consequences for vulnerable populations such as the young and elderly, as well as our agricultural interests in Iowa. Extreme weather events, such as the recent flooding in Polk County, have already demonstrated the danger of climate change we are facing today.

Despite Iowa facing these grim predictions, Schnoor and Tackle urge Iowans that they can still take action. Supporting renewable energy, voting in local elections, and joining local organizations that spread information about climate change are all presented as important ways to help protect our future.
