The water system in the City of Hiawatha, Kansas, along with the RWD#2, tested with high levels of nitrate. The city issued a warning this week, in which officials warned not to give city water to infants, by itself, or for use with juce or formula.
Some of the usual workarounds do not apply in this case. Boiling, freezing, filtering, or letting water stand does not reduce the nitrate levels. Excessive boiling can make the nitrates more concentrated, because nitrates remain behind when the water evaporates.
Nitrates are a concern for infants because they can’t process nitrates in the same way adults can. Thus, most adults and children over six months of age can drink the tap water. You may wish to consult a physician if you are pregnant or suffer from some specific chronic health concerns.
The City of Hiawatha says it will consumers know when the amount of nitrate is again below the limit.
The city is currently working with an engineering firm and investigating funding for a water treatment plant proposal for nitrate removal. Meanwhile, testing for nitrates continues.
