COLUMBUS (WCMH) — The City of Columbus has canceled a tap water nitrate advisory that was issued on June 30.

Officials say that the most recent results from water testing show nitrate levels below the standard.

There is no longer a need to use bottled water for infants under the age of 6 months old or women further than 30 weeks in pregnancy.

It had been a frightening few days for new mom Amanda Jordan. She says she worked to keep her two-month-old daughter away from ingesting any city tap water.

Jordan explains, “It is very scary, you know. Sometimes you don’t know very much about it so you get online and look it up to see what it means and what it can do to you and everything.”

She had been taking special precautions like, “buying bottled water for the time being until everything comes back safe again. That’s my thing.”

These are precautions she no longer needs to take, according to the city.

City water quality scientists were able to track the water with the high nitrates all the way from Marion County down the Scioto River to the Dublin Road water intake plant.

City of Columbus Water Quality Insurance Lab Manager Rod Dunn says his team monitored real time data and took water samples along the river by hand.

“We look at the hydrograph as the water flows past to see if the water is ascending or descending and see where that wave of flow from the rain event is moving through.”

He says water at the Dublin Road plant has an acceptable level of nitrates now as does the water upstream.

Dunn adds there is no more fear of high nitrate levels for at least the remainder of the summer.  He explains, “It is rain driven, but now that the rain has washed the nitrate off, we should be good for the rest of the summer.”

There are three times of year when high nitrate levels could be possible according to city water scientists.  Late spring and early summer, October or November, and during the first major spring thaw.

New technology is being put in place by the city to avoid this type of problem in the future. A new ion exchange facility will pull nitrates out of water before it reaches your tap in the future.  This new facility will open by the end of 2017.

Too much nitrate in your body makes it harder for red blood cells to carry oxygen. The EPA says nitrate can get into your water supply “when products containing nitrogen, such as fertilizer or manure, are applied to land, natural bacteria living in the soil can change nitrogen into nitrate. Rain or irrigation water can carry the nitrates down through the soil to the groundwater below.”

Most water filtration pitchers or the kind that attach to your faucet will not work on nitrates. The water industry says distillation water filters and reverse osmosis water filters, which both attach to your plumbing, do catch nitrates.
