Safe Drinking Water: FDA Standards Explained (2024)

Regulations concerning potable liquid safety within the United States are primarily established and enforced by the Environmental Protection Agency (EPA). These regulations set maximum contaminant levels (MCLs) for various substances that may be present in municipal supplies. An example includes permissible levels for lead, arsenic, and certain organic chemicals. These guidelines aim to minimize potential health risks associated with consumption.

Adherence to these established limits protects public health by preventing waterborne illnesses and chronic health problems linked to prolonged exposure to contaminants.

The development and consistent application of these protective measures have drastically reduced those risks, providing a safer and more reliable source for the population.
