After nearly 30 years of a stagnant Lead and Copper Rule, the Environmental Protection Agency announced a new proposal to update the regulation. The new regulations are aimed to increase lead identification, sampling, and strengthen treatment by increasing the number of hours a service provider needs to notify a customer that their water is contaminated with lead.

The Natural Resources Defense Council and other environmental activists have expressed concern that the new regulation allows communities more to time to replace the lead service lines, indicating these regulations may be weaker than the previous. The new proposal also establishes a lower “trigger level” of lead to 10 parts per billion from 15 parts per billion. The main counterargument is health experts have never established that any level of lead can be sustainable. “Even low levels of lead can cause harm to developing brains and nervous systems, fertility issues, cardiovascular and kidney problems, and elevated blood pressure. Pregnant women and children are particularly vulnerable,” the NRDC said in a statement.

The last major lead pipe exposure in Iowa outbreak was December 2016. More than 6,000 Iowans were exposed to contaminated water for over six months. The issue brought up major incongruency in the method to solve the problem between University of Iowa engineers or Iowa Departments of Public Health and Natural Resources.

Agronomy researchers at Iowa State University have proposed ideas for an ambitious and much-needed update to Iowa’s agricultural drainage system. Their study makes suggestions for mitigating the effects of altered precipitation patterns due to climate change while reducing pollution to air and water.

The concept of “sustainable intensification” (the authors define this as “producing more food from the same amount of land with fewer environmental costs”) is at the core of the research. ISU agronomist Michael Castellano led the study in partnership with University of Kentucky and the Swiss Federal Institute of Technology ETH-Zurich.

Artificial drainage systems are comprised of underground pipes, tiles and drains that move water off farmland, discharging it into ditches that flow into natural surface waterbodies. Without this network, most of Iowa’s land would be too waterlogged to farm, but drainage systems increase runoff of nutrient and bacterial pollution from fields into waterways.

The increasing frequency of both intense rain events and draught in Iowa due to climate change is also putting extra pressure on those systems, which were designed before Iowa agriculture became so intense.  The study, published in Nature Sustainability, describes several solutions. “Controlled drainage,” or installing gates that can temporarily open/close at the ends of drains, could allow farmers to increase drainage during wet springs and retain more water during dry summers.

Installing narrower, shallower drains could further reduce nutrient concentration in drainage water, the authors claim. They say it could also reduce needed fertilizer inputs and decrease greenhouse gas emissions from the soil.

The study also describes the need to increase on-farm conservation practices, like returning some farmed land to wetland, in conjunction with updating infrastructure.

 

Iowa Climate Statement 2019: Dangerous Heat Events to Become More Frequent and Severe


Kasey Dresser and Tyler Chalfant | October 7, 2019

Just weeks after July 2019 became the hottest month in 140 years of recordkeeping, 216 science faculty and researchers from 38 Iowa colleges and universities have endorsed the ninth annual Iowa Climate Statement 2019: Dangerous Heat Events to Become More Frequent and Severe.

The statement, released on September 18, warns Iowans and Midwesterners of sobering extreme heat projections for the region. Based on the most up‐to‐date scientific sources, the statement makes clear the urgency of preparing for dangerously hot summers in the coming decades.

Betsy Stone, Associate Professor in the Department of Chemistry at the University of Iowa, reads this year’s statement in the video above. Access the full written statement here.

 

Veggie Rx coming to Johnson County

A $50,000 grant from MidWestOne Bank has been awarded to Johnson County community organizations for the creation of the Veggie Rx Pilot Program. This 26-week program aims to help individuals with diet-related diseases by providing them with fresh fruits and vegetables.

Participants of the program will receive care from the University of Iowa Health Care’s upstream clinic and their food from either the Coralville or North Liberty Community Food Pantry. With routine access to locally grown fresh fruits and vegetables, individualized dietary guidance, and educational activities related to healthy food, the participants will hopefully see positive changes in their daily life. Food will be purchased directly from Sundog Farm in Solon, Wild Woods in Iowa City, and Echollective in Mechanicsville.

MidWestOne Bank CEO Charlie Funk said the bank was “delighted to lend support to the Veggie Rx Program,” which will give back not only to local residents but provide business to local farms as well.

Fast food chains experiment with meatless patties

Fast food chains across North America are experimenting with meatless patties amid a growing concern about environmental repercussions imposed by the meat industry.

McDonald’s will begin selling plant-based patties at select locations in Canada next week, a plant, lettuce, and tomato patty known as Beyond Meat. Tim Hortons, KFC, and Dunkin Brands have also experimented with Beyond Meat patties. According to a report from Reuters, since Beyond Meat was listed on the stock market in May, its shares have roughly tripled in value.

McDonald’s announcement comes after Burger King rolled out its own version of a plant-based burger, coined the Impossible Whopper.

A recent UN report from the Intergovernmental Panel on Climate Change outlined the meat industry’s effects on the changing climate. According to the report, 4 percent of the food sold by weight in the U.S. is beef, which accounts for 36 percent of food-related emissions. The report adds that cattle is the leading source in livestock emissions, amounting to an estimate of 65-77 percent.

The report warned that if nothing is reformed in industrial agriculture, emissions from this production could increase 30-40 percent by 2050. In an analysis from Greenpeace, 23 percent of greenhouse gas emissions are a result of agriculture and land use.


Iowa remains the country’s leading producers of pork and large hog operations continue to rapidly increase. Waste management and water quality has been an ongoing issue for the farm state as a result of large farm operations.

UI professor and researcher calls on economic reform to address the changing climate


By Julia Shanahan | September 20th, 2019

Jerry Schnoor, University of Iowa civil and environmental engineering professor and co-director of the Center for Global and Environmental research, wrote an op-ed in the Des Moines Register, calling for economic reform to reduce global carbon emissions.

Schnoor listed several economic changes that would help to reduce carbon emissions by 45 percent in the next ten years:

  • Install solar panels and build large solar power plants
  • Improve battery storage
  • Massive reforestation
  • Implement regenerative agriculture to keep carbon in the ground
  • Expand electrical vehicle usability

Schnoor pointed to extreme weather events like the spring flooding from the Missouri river, category five hurricanes, wildfires, drought, and failed crops. This op-ed comes ahead of the Sept. 20 global climate strikes, where people of all ages from all over the world are rallying for environmental reform. 

Schnoor says in the piece that “time is running out” to address the changing climate, writing,  “Without a drastic reduction in burning of fossil fuels now — a reduction of 45% in the next 10 years — we commit ourselves to increasing climate catastrophes at great economic cost.”


In Iowa, where agriculture is a leading industry, many have called on farmers across the midwest to begin more sustainable farming methods, like planting cover crops, leaving organic materials in the fields after harvest, and adding additional crops to a soybean-corn rotation.

The world’s protein companies still failing to address their environmental impact

The Coller FAIRR Protein Producer Index, in its second active year, just released their report analyzing the environmental, social, and governance risks of meat, dairy, and farmed fish producers. One large take away from this year’s study was the lack of attention given to environmental and animal welfare by some of the world’s largest protein producers.

The FAIRR Index looked at 60 different companies and found evidence of lacking sustainability efforts for greenhouse gas emissions, water pollution, food waste, conditions for workers, antibiotic use, and animal welfare. Only 30% of the analyzed companies were able to give the researchers specific environmental strategy plans which focused only on reducing greenhouse gas emissions. One-quarter of the companies refused to even disclose their use of antibiotics on their animals.

As more research regarding climate change emerges, this isn’t just a problem for consumers. The conversation is shifting toward some of the financial consequences of severe weather for these large companies.

“What we’re seeing is that companies in the sector are contributing to many of the risks we discuss in the report, but they’re also deeply vulnerable…to the impacts of climate change,” says FAIRR’s Head of Research, Aarti Ramachandran. In an interview with Forbes, Ramachandran gave an example of an Australian Agricultural Company that lost over $100 million in damages due to extreme flooding.

Ramachandran does leave the report on a positive note acknowledging the increased investments in plant-based proteins by meat and dairy companies. He stated, “we think that, overall, there should be a rebalancing of protein so that animal protein consumption doesn’t continue to grow at the same trajectory, and so that there is a sustainable balance between plant-based and animal-based food.”
