The Pennsylvania Department of Environmental Protection (DEP) has issued a Code Orange Air Quality Alert for Wednesday, June 4, 2025, covering Berks, Lehigh, and Northampton counties.
A Code Orange alert signifies that air pollution levels are expected to be unhealthy for sensitive groups, including children, older adults, and individuals with respiratory conditions such as asthma, lung disease, or heart disease. On days with elevated air pollution, even moderate outdoor activity can exacerbate symptoms in these populations.
Residents in affected areas are advised to reduce or avoid strenuous outdoor activities, particularly during the afternoon and early evening hours when air quality typically worsens due to higher temperatures and increased ozone formation.
This alert specifically addresses ground-level ozone and fine particulate matter, which can contribute to respiratory issues and other health problems. The DEP recommends that vulnerable individuals stay indoors as much as possible and monitor symptoms if they are affected by the poor air quality.
