In January, citizens of Fremont, Ohio, were warned for the third time in less than six months that their drinking water contained high concentrations of nitrate.

Nitrate (NO3) is colorless, odorless, and tasteless. It’s found naturally in the environment, and it’s harmless in small amounts. However, when large amounts of nitrates from agricultural operations and waste dumps contaminate drinking water, they make the water dangerous. In the body, nitrate is converted to nitrite, which can reduce oxygen supplies to organs like the brain. This is especially dangerous for infants. Nitrate levels of 10 mg/l or higher can cause methemoglobinemia, or “blue baby syndrome,” in which the ability to utilize oxygen is reduced.

Nitrate levels in the water of Fremont, OH, were found to be 11.3 mg/l, and officials issued an advisory and warned that infants under the age of 6 months should not be given tap water.

Symptoms of blue baby syndrome include blue skin (especially around the eyes and mouth), shortness of breath, weakness, dizziness, and headache. If you suspect methemoglobinemia, take the baby to the hospital immediately. If left untreated, blue baby syndrome may cause permanent brain damage or death.

Elevated levels of nitrates in drinking water have also been linked to thyroid problems, increased risk for birth defects, increased risk of diabetes, and increased mortality rates for several different types of cancer.

Protect your water from nitrate contamination by using home water filters.
