‘It’s getting worse’ – U.S. failing to stem tide of harmful farm pollutants in Mississippi River

VENICE, Louisiana —  Kindra Arnesen is a 46-year-old commercial fishing boat operator who has spent most of her life among the pelicans and bayous of southern Louisiana, near the juncture where the 2,350-mile-long Mississippi River ends at the Gulf of Mexico.

Clark Porter is a 62-year-old farmer who lives in north-central Iowa where he spends part of his day working as an environmental specialist for the state and the other part raising corn and soybeans on hundreds of acres that his family has owned for over a century.

Though they’ve never met, and live 1,100 miles apart, Arnesen and Porter share a troubling kinship – both of their communities are tied to a deepening water pollution crisis that is fouling the environment and putting public health in peril across multiple U.S. states.

Voluntary efforts will never achieve Iowa's goal to curb nitrogen runoff, water quality researcher says

Iowa will never achieve its goal to reduce nitrate runoff from Iowa farm fields relying only on voluntary actions of farm operators, according to a hydrologist who has done extensive research on the state's waterways and water quality.

The state has not only has failed to achieve its goal to reduce nitrogen runoff by 45 percent over the past eight years, the 5-year average of nitrate flowing into the Mississippi River has increased, up more than 100 percent between 2003 and 2019, according to Larry Weber, Ph.D, a research engineer with the University of Iowa's IIHR-Hydroscience and Engineering Department.

526,000 tons of nitrates 'exported' into Iowa rivers and streams in 2016; improved monitoring network providing better tracking of farm chemical runoff

An estimated 526,000 tons of nitrates were "exported" into Iowa rivers and streams in 2016, eventually flowing down the Mississippi River to the Gulf of Mexico and adding to the so-called "dead zone" where fish cannot survive.

According to the Annual Progress Report of the Iowa Nutrient Reduction Strategy (NRS) group released last week (12/12), more than 29 pounds of nitrogen from each of Iowa's 35.75 million acres of crop land ended up in state waterways.
