The northeast Nebraska town of Creighton is still under what’s called an acute nitrate violation — which restricts some residents from drinking water. The city had lifted the violation last week but it’s been re-instated.
City administrator Justin Lilly says after talking to some experts, they decided to keep violation active. Test samples confirmed the water that’s sent to the water tower for public consumption was back under ten parts-per-million but state officials wanted to do more testing.
Lilly says a variety of factors can contribute to elevated amounts of nitrates in the water and the city is looking for ways to avoid a repeat.
Nitrates occur naturally with rainfall and snowfall, they’re put on by agricultural producers and they wash off our lawns. He’s mapped areas of high nitrate concentration and says much of the city and surrounding area have elevated levels.
Lilly believes more cities nearby will have to cope with similar issues.
During the acute nitrate violation, infants under six months, pregnant women and nursing mothers should not drink the water. Meanwhile, boiling the water can actually make the nitrate concentration level higher as the nitrates are left behind as water evaporates.
