Des Moines Water Works Reports Record-High Nitrate Levels

Des Moines Water Works general manager William G. Stowe recently wrote a letter to the editor in the Des Moines Register explaining that nitrate levels in the water are at record highs…again.

In 2013, Des Moines Water Works found that the nitrate levels in both the Des Moines and Raccoon Rivers were at a record high and caused ratepayers an extra $1 million in treatment costs to reduce the nitrate concentration. In addition to the added cost, consumers’ tap water safety was compromised. With the September 2014 nitrate levels setting another record, it is likely that the 500,000 consumers who depend on Des Moines Water Works for clean, safe water will suffer the same consequences as last year.

Where does nitrate come from?

Nitrate is a naturally occurring compound in the soil and is essential to all life forms. Nitrate can become harmful, however, if concentration levels exceed 10 mg/L in water. Many variables contribute to nitrate concentration, including weather and erosion. But human interference is contributing to higher nitrate levels at a steadily increasing rate. Fertilizer runoff as well as leakage from septic tanks and sewage are among the main contributors to nitrates in drinking water. Stowe expresses his frustration in his letter with Iowa policy failing to implement regulations for contributors to rising nitrate levels, such as industrial agriculture and artificial drainage systems.

What are the health risks?

When levels are higher than the Environmental Protection Agency’s recommended value of 10mg/L, nitrate can cause methemoglobinemia, otherwise known as blue baby syndrome. Methemoglobinemia is an oxygen-depriving condition where nitrate turns into nitrite in the body and gets absorbed in the bloodstream. The nitrite causes hemoglobin, responsible for transporting oxygen in the blood, to convert into methemoglobin, which cannot transport oxygen as effectively. Infants are especially at risk of methemoglobinemia because their stomach acid is not as strong as it is in older children or adults to prevent an increase in bacteria that convert nitrate to nitrite. While infants are more susceptible to methemoglobinemia, pregnant women, adults with reduced stomach acidity, and people deficient in the enzyme that changes methemoglobin back to normal hemoglobin should be cautious about the amount of nitrate they consume.
