In the decades since Congress passed the Clean Air Act in the early 1960s, air quality monitoring has become one of the EPA’s central tools to ensure the agency delivers on the promise to protect people from polluted air. The EPA, in partnership with state regulators, oversees a network of roughly 4,000 monitors across the country that measure the levels of six pollutants detrimental to human health, including ozone, sulfur dioxide, and particulate matter.
