5 Takeaways From Iowa Water Quality Report that Points to Agriculture as Nitrates Source

POLK COUNTY, IOWA, AUG 5 – A two-year study found 80% of nitrate pollution in Polk County rivers comes from agriculture, with levels among the highest nationwide, prompting calls for stronger regulation.

  • On Monday night at Drake University's campus, 16 researchers hosted by the Harkin Institute and Polk County presented the CISWRA report, accepted last month, on water quality issues.
  • According to CISWRA findings, the report shows threats to Polk County's water system stem from human activities, with about 80% from agricultural land, 40% from fertilizers, and 20% from manure.
  • Data shows the Raccoon River and Des Moines River each year receive about 50,000 tons of nitrogen, as researcher Elliot Anderson indicated.
  • Consequently, Central Iowa Water Works, serving over 600,000 people, issued a water consumption ban due to nitrate levels surpassing 10 mg per liter.
  • Amid funding reductions, the state will contract its nitrate monitoring network from about 80 sensors to about 20 next year, researchers warn it will limit data.
