Illinois has released the 2023 Biennial Report of the Nutrient Loss Reduction Strategy (NLRS), detailing ongoing efforts to improve water quality. Developed by the Illinois Environmental Protection Agency (Illinois EPA), Illinois Department of Agriculture (IDOA), and University of Illinois Extension, the report outlines progress in reducing nutrient pollution affecting local waterways and the Gulf of Mexico.

The NLRS, initiated in 2015, aims for a 45% reduction in nitrogen and total phosphorus loads, with interim targets set for 2025. The strategy involves collaboration among academia, private sector entities, non-profits, wastewater agencies, and government bodies at various levels.

"This Biennial Report showcases the commitment of the agriculture industry to be good stewards of the land," said IDOA Director Jerry Costello II. "Through the works of the NLRS, the Department learned the value of having a ‘boots on the ground' conservation presence state-wide working directly with farmers implementing in-field practices focused on soil health."

The report highlights initiatives from 2021-22 aimed at reducing nutrient loss across agricultural, wastewater, and urban stormwater sectors. It also addresses challenges such as climate change impacts on nutrient loads.

"This report provides a candid update on the outcomes and ongoing initiatives across all sectors, particularly in light of the climatic challenges faced by Illinois and neighboring states within the Mississippi River basin," said Illinois EPA Director John J. Kim. "Our collective endeavor is to integrate more effective measures to curtail nutrient pollution."

Nutrient pollution from excess nitrate-nitrogen and phosphorus affects ecosystems and contributes to oxygen depletion in the Gulf of Mexico's "dead zone." Illinois is part of a task force addressing this issue.

Despite varied results from recent measures, significant reductions were noted in certain areas. The point source sector reduced total phosphorus discharges by 34% since 2011 due to improved wastewater treatment strategies.

Dr. Shibu Kar from University of Illinois emphasized continued research efforts: "The findings in this report underscore the need to deepen our understanding of nutrient dynamics. It's imperative that we bolster our research efforts and foster stronger ties with farming communities."
