What is the recommended maximum concentration of nitrates in MCO for nitrates?

The recommended maximum concentration of nitrates in a manufacturing or industrial context, specifically referring to the Maximum Contaminant Level (MCL) for nitrates in drinking water as set by the Environmental Protection Agency (EPA), is 10 parts per million (ppm). This standard aims to protect public health, particularly for vulnerable populations such as infants, who may suffer from methemoglobinemia, or "blue baby syndrome," due to high levels of nitrates in water.

The significance of this value is rooted in health-based risk assessments and the potential harmful effects of excessive nitrate consumption. By establishing guidelines such as this one, regulatory agencies strive to ensure safe drinking water and minimize potential health hazards associated with nitrate exposure. Therefore, the choice of 10 parts per million aligns with established safety standards and public health objectives.
