Roughly 30 students, professors, and researchers from six different institutions met in Muscatine this week to discuss a collaborative research effort to improve land, water, and air quality in the Midwest.

This Midwestern project is part of a nation-wide project known as the Critical Zone Observatory (CZO) an effort by the National Science Foundation to “[study] the zone where rock meets life.” The Midwestern project is called the CZO-IML (Intensely Managed Landscapes) and focuses on watersheds and lands in Illinois, Iowa, and Minnesota.

The Lucille A. Carver Mississippi Riverside Environmental Research Station (LACMRERS) in Muscatine hosted the IML-CZO conference which began Tuesday and ends today. This marked the second annual meeting for what will be a five year project.

“The first year was a lot of planning and field campaigns. The second year we’ve collected some data will be able to get that back to look at the results. We finally have some things to discuss, some real science,” said LACMRERS Director Doug Schnoebelen.

Schnoebelen, who also serves as a contributor for the IML-CZO project as well as a member of CGRER, said he hopes this research will be helpful not just for farmers and watershed managers but also for the general public.

“We’re hoping to look at an integrated approach and that’s what the Critical Zone is, being able to say something about water movement, soil conservation, transformation of carbon and energy in the environment. All of these things are really critical to the soil, the water, and the way we live.”

The conference brought together researchers from Indiana University, Northwestern University, Purdue University, University of Illinois, University of Iowa, and University of Tennessee. Schnoebelen said this emphasis on collaboration over competition has been key to the success of the project. He added that he is also grateful the CZO chose to support a Midwestern research project since much of the CZO’s other research takes place on the coasts.

“I think it was important when the national team came out and they realized how managed our landscape was and how important this research really was. It’s not just flyover country in the Midwest, it’s a critical part of our economy for food and energy.”

Iowa companies fined for environmental violations


Nick Fetty | July 24, 2015

The Iowa Department of Natural Resources has issued fines against roughly a dozen Iowa companies for environmental violations.

The announcement was made earlier this month and includes a $10,000 fine for air quality violations against the Mason City-based ethanol production facility Golden Grain Energy LLC. The DNR cites that the company (1) exceeded permitted emission limits and failed to properly maintain required records, (2) failed to properly maintain equipment, (3) failed to continuously operate an emissions monitoring system, and (4) failed to continuously monitor thermal oxidizer temperature. In 2012, the company was fined $5,750 for air quality violations.

Other consent orders issued by the Iowa DNR include a $5,000 fine for Farm Nutrients LLC (Kossoth County) for manure runoff into state waters, a $6,500 fine for Twilight Investments LLC (Fremont County) for manure application violations, $5,575 for Smith Ag Inc. (Mitchell County) for manure discharge violations resulting in a fish kill, $8,000 for M.G. Waldbaum Company (Hancock County) for past permit violations, and $1,000 for Porter Farms, Inc. (Jefferson County) for manure disposal.

A full list of actions taken by the Iowa DNR is available on its website.

An Iowa utility company plans to phase out several of its coal-fired power plants in the near future.

Interstate Power and Light Co. – a subsidiary of Alliant Energy – announced on Wednesday that it will either close or convert to natural gas five of its coal plants while an additional two plants will be equipped with pollution control technology. The cost for these projects is estimated at $620 million. Wednesday’s announcement marks the 200th closure of a coal plant nationwide over the last five years.

The Sierra Club, the state of Iowa, and other local and federal agencies sued Interstate Power and Light alleging the company was in violation of the Clean Air Act. In addition to the closures and upgrades to its facilities, Interstate Power and Light has also agreed to a pay a $1.1 million civil penalty within 30 days of the settlement. The company will also spend an additional $6 million on other environmental projects including the development of solar facilities, the replacement of traditional utility bucket trucks with hybrid trucks, and the development or expansion of anaerobic digesters.

“For several years, we have been executing a plan to create cleaner and more efficient ways to generate energy for our customers,” Alliant Energy Iowa utility President Doug Kopp said in a press release. “Iowans are already seeing the benefits of our work, and our next projects will deliver even more clean-energy solutions.”

Emission reduction projects will take place on two of the company’s largest facilities in Lansing and Ottumwa while smaller power stations in Burlington and Cedar Rapids will convert to natural gas. Alliant generating stations in Clinton, Dubuque, and Marshalltown have already transitioned to natural gas.

Eastern Iowa gets its first Tesla station

Two Tesla cars got their first charge in eastern Iowa last week.

The fully electric cars were part of a ribbon cutting ceremony at a new Tesla charging station at Bass Family Farms along Highway 30 in Mt. Vernon. Tesla owners can use the charging station for free, which draws power from one of the farm’s buildings.

Bass Family Farms, a chemical-free farm, is now part of Tesla’s Destination Charging Program, which partners with businesses like hotels and restaurants to provide destinations for Tesla owners to charge. It’s part of a growing effort to increase electric car traffic in places with charging stations few and far between. A Tesla Model S can go 265 miles on a single charge, and charging can take several hours depending on the power source. Tesla’s growing Supercharger infrastructure boasts half charge times of just 30 minutes.

While road trips through Iowa can be difficult with only a few charging stations spread along the state’s highways, at-home charging is becoming an increasingly viable option. Tesla has partnered with solar energy provider SolarCity to make home solar panel installation more affordable, meaning Tesla drivers could have a zero emission commute.

Study: Fireworks contribute to air pollution, public health issues

Firework shows have long been a Fourth of July tradition but new research finds that they could be more damaging to the environment and public health than previously thought.

A recent study published in the journal Atmospheric Science found that firework shows lead to a 42 percent increase in concentrations of fine particulate matter in the air on July 4 alone. Researchers from the National Oceanic and Atmospheric Association (NOAA) looked at data from 315 sites around the country between 1999 and 2013 and found that ten of the sites saw air quality levels that would be deemed unsafe based on Environmental Protection Agency standards. Air quality was found to be poorest between 9 p.m. and 10 p.m. on Independence Day with levels generally returning to normal around noon on July 5.

“We chose the holiday, not to put a damper on celebrations of America’s independence, but because it is the best way to do a nationwide study of the effects of fireworks on air quality,” said Dian Seidel, a senior scientist at NOAA’s Air Resources Laboratory in College Park, Maryland. “These results will help improve air quality predictions, which currently don’t account for fireworks as a source of air pollution. The study is also another wake up call for those who may be particularly sensitive to the effects of fine particulate matter.”

Data from EPA shows that high levels of fine particulate matter can cause health issues ranging from heart attacks to respiratory problems.

A recent report identifies 2015’s most promising technologies for addressing climate and other environmental concerns.

The 157-page report – “Top Technologies in Clean & Green Environment – 2015” was published earlier this month in Research and Markets. The authors examine ways to address environmental concerns such as water scarcity, energy depletion and global warming. Specifically the authors look at the top 10 innovations in the Clean and Green Environment sector: (1) Atmospheric Water Generation, (2) Waste-to-Energy, (3) Waterless Technologies, (4) Water-Energy Efficient Technologies, (5) Solid Waste Upcycling, (6) Indoor Air Purification, (7) Reverse Osmosis, (8) Air Filtration, (9) Membrane Distillation, and (10) Capacitive Deionization.

Water quality and water scarcity issues have forced innovators to develop waterless and water-efficient technologies such as no-flush urinals and waterless printers. In addition to water, the report also examined technologies to protect the land (composting, waste-to-energy), the air (atmospheric CO2 removal, particulate air pollution control), and the general environment (biomass energy with carbon capture storage, non-vapor HVAC compression technology).

The report also identified six key challenges that stand in the way of green technologies: (1) high energy intensity, (2) net environmental impact, (3) lack of funding, (4) lag in supporting technologies, (5) end-user skepticism, and (6) unknown effects.

Transcript: Tornadoes

A recent University of Iowa study has found that smoke from fires can contribute to the intensity of tornadoes.

This is the Iowa Environmental Focus.

The study was published in the journal Geophysical Research Letters earlier this year. The researchers examined how smoke affected a system of severe weather events which occurred on April 27, 2011. This system produced 122 tornadoes and caused 313 deaths across the southeastern United States. The study found that smoke particles in the atmosphere lowered the base of the clouds and affected the speed of the winds which increased the intensity of the tornadoes. The research was conducted using computer simulations.

CGRER co-director Greg Carmichael and CGRER postdoctoral fellow Pablo Saide were co-authors of the study, along with researchers from other University of Iowa departments, the University of Wisconsin-Madison, and NASA.
