About 15% of those private wells exceeded the federal drinking water standard.
Nebraska Public Media reports nitrate levels are also rising in roughly a third of the 444 public water systems analyzed, according to the study, which was ordered by the Legislature at the request of Gov. Jim Pillen.
Nitrates in water are linked to a variety of diseases, pregnancy complications, birth defects and various cancers.
According to Nebraska Public Media, nitrate in Nebraska largely stems from agricultural practices.
"It forms when soil bacteria break down nitrogen, often from commercial fertilizers and animal waste. When fertilizer is sprayed on cornfields and not used up by the crop, the excess nitrate can leach into the soil and eventually the water supply, especially when applied excessively. The over-application of manure on fields can do the same."
Nebraska has the highest pediatric cancer rate west of Pennsylvania.
If you have a private domestic well on your farm or acreage, and want to test your well for nitrate and/or bacteria, request a kit from the Nebraska Department of Health and Human Services’ Public Health Environmental Lab. Nitrate sample kits cost $16, and coliform bacteria sample kits cost up to $17.
