Experts are cautioning that the current 10 parts per million nitrate standard does not accurately reflect real-world situations, even as the standard remains in place. No-till farming practices are highlighted as a way for farmers to help address the issue of 'blue baby syndrome' and other nitrate-related health concerns.

Why it matters

Nitrate contamination in drinking water can lead to a serious condition called 'blue baby syndrome' that affects infants. As no-till farming methods gain popularity, they offer a potential solution to help reduce nitrate runoff and protect public health, though the outdated regulatory standards remain a challenge.

The details

Jay Lehr, a senior scientist with Environmental Education Enterprises in Ostrander, Ohio, says the current 10 parts per million nitrate standard is likely here to stay, even though it does not accurately reflect real-world situations. No-till farming practices, which help reduce soil erosion and nutrient runoff, are highlighted as an effective way for farmers to address nitrate concerns and the risk of 'blue baby syndrome'.

• The nitrate standard has been set at 10 parts per million for many years.
