Cancer-Related Disease and Deaths Spur Actions to Fight Farm Chemical Contamination in Corn Belt

When directors of the public water utility in Des Moines, Iowa, went to court in 2015 to try to stop toxic farm nutrients from contaminating the city’s drinking water, they knew the federal lawsuit they filed would be seen as not just a desperate step to protect public health, but also a brazen act of defiance that would provoke a ferocious response from Iowa’s powerful farm and political leadership.

As they anticipated, a cohort of agricultural interests joined then-Gov. Terry Branstad in beating back the lawsuit, which Branstad declared an act of “war on rural Iowa.” 

Des Moines Water Works alleged that drainage districts in three Iowa counties had polluted the Raccoon River with nitrates, forcing costly efforts by Des Moines to render the polluted water safe for drinking. A US District Court judge dismissed the case in 2017 after ruling that Iowa law immunizes drainage districts from damage claims.

It was the last time a government entity in Iowa or any other Corn Belt state made a focused attempt to reduce human exposure to suspected cancer-causing commercial fertilizers and a flood of livestock manure that routinely drains from farm fields into groundwater, streams, and rivers.   

Until now.  Read more

“We Can’t Sit Back” – Amid Polluted Water and Climbing Cancer Rates, Iowa Eyes Farm Chemicals

Faced with a startlingly high cancer rate in the key US farm state of Iowa, public health leaders are taking the politically precarious step of acknowledging that preventing disease necessitates cutting exposure to potentially cancer-causing chemicals, including those used in agriculture.

In a departure from other state cancer prevention programs, which rarely address environmental risk factors for cancer other than radon, a known cause of lung cancer, Iowa is working to better understand and make the case for limiting exposure to pesticides, commercial fertilizer, and animal manure used and generated by Iowa agriculture, among other environmental contaminants.

How Big Ag Pollutes America’s Waters and Makes Money Doing It

It’s been 33 years since an Iowa State University agronomist named Fred Blackmer thought he’d struck gold for Midwestern corn farmers. Using a fairly simple three-step method, Blackmer developed an analytical tool that could accurately tell farmers exactly how much fertilizer their fields needed to produce abundant harvests each season.

The analytics Blackmer perfected showed not only how much fertilizer the corn crops would need to meet production targets, but also exposed how much could be wasted. Blackmer ultimately determined that farmers were applying a staggering 500 million excess pounds of nitrogen each year, a practice that not only wasted farmers’ money but also wreaked havoc on the environment as the nitrogen not taken up by plants drained from farm fields to contaminate rivers, lakes, and streams.  

Despite what Blacker saw as obvious benefits to producers, not to mention the environment, his method failed to gain significant traction in farm country. Farmer allegiance to the excessive fertilizing practices pushed by the so-called “Big Ag” production industry and aligned academic institutions left Blackmer’s common sense approach on a shelf gathering dust.  Read more
