Selenium, nitrate levels still high

Not considered health issue yet

Humphrey’s selenium and nitrate levels remain high, but it does not constitute an immediate health issue at this point.

According to the Nebraska Department of Water, Energy, and Environment (DWEE) “Another selenium MCL violation has been issued after a recent sample again showed elevated selenium levels in Well 20011. Although this is the third quarterly violation of this type since August 2025, selenium is not considered an immediate health threat.”
