    Conservation & Sustainability: fertilizer nitrates

    UC Davis researchers insert a device that continuously collects water samples underground, providing real-time data on nitrate contaminant movement. Isaya Kisekka/UC Davis Heavy rains can cause contamination in just 10 days, UC Davis study finds. Extreme weather spurred by climate change, including droughts and heavy rains, may increase the risk of nitrates from fertilizers ending…

    EPA Restarts Assessment of Health Risks from Nitrate in Water

    The agency will evaluate the hazards from agriculture’s primary water pollutant. Farming regions in northeastern Nebraska and elsewhere have some of the highest concentrations of nitrate in streams and groundwater due to decades of fertilizer use. Photo © J. Carl Ganter/Circle of Blue. The U.S. Environmental Protection Agency, reversing a Trump-era decision, is restarting a…

    Iowa farms using low-tech systems to filter fertilizer-borne nitrates from water

    Photo: A worker shovels wood chips in a bioreactor trench in a farm field, on March 28, 2023, near Roland, Iowa. Low-tech systems called bioreactors and streamside buffers help filter nitrates from rainwater before it can reach streams and rivers. (AP Photo/Charlie Neibergall) Nick Helland’s central Iowa farm looks much like every other nearby farm on…

  • Study confirms nitrate can release uranium into groundwater

    Study confirms nitrate can release uranium into groundwater

    New research finds that nitrate … can help transport uranium to groundwater — when the nitrate levels exceed the regulatory threshold of 10 parts per million. New research experimentally confirms that nitrate can help transport naturally occurring uranium from the underground to groundwater, according to a press release from the University of Nebraska-Lincoln. The new…
