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.

Farm bureau crows about water quality progress; nutrient reduction report stats show otherwise

on Thu, 07/23/2020 - 21:22   by news

The Iowa Farm Bureau unleashed its public relations machine after release of the 2018-19 Nutrient Reduction Strategy (NRS) Report July 2, heralding what it called "clear and significant strides" on reducing nitrogen and phosphorus leaching from farms fields into state streams, rivers and lakes.

Problem is the farm bureau either failed to read the report statistics on nitrogen and phosphorus runoff, or simply chose to ignore the research results and spin the findings.

Group issues scathing report on EPA, states' efforts to reduce nutrient pollution of Mississippi River; cites 2015 'close call' involving QC water supply

Voluntary initiatives by the U.S. EPA and 10 states bordering the Mississippi over the past 20 years have largely failed to rein in harmful nitrogen and phosphorus pollution by cities, farms and industry, according to a scathing report issued today (11/17) by an environmental and legal group focused on protecting the Mississippi River watershed.

"Though the EPA has consistently and emphatically urged states to take measures to combat nitrogen and phosphorus pollution, its encouragement has come without enforceable regulations, specific deadlines or funding for implementation," the report by the Mississippi River Collaborative says. "Not surprisingly, the problem persists, especially in the Mississippi River, despite a variety of Clean Water Act tools and viable regulatory options available to states."

The analysis of nutrient pollution of lakes, rivers and streams in the Mississippi River watershed – entitled "Decades of Delay" – says the 10 states bordering the country's longest river have failed to establish any numeric limits for nitrogen discharges and only two states have set numeric limits for phosphorus pollution.
