<UPDATED> Allegheny County Health Department Issues Mon Valley Air Pollution Warning for Tuesday, All of Wednesday

The Liberty-Clairton area woke up to unhealthy air quality again Tuesday, with EPA’s NowCast AQI soaring to 183 and hourly monitor data showing elevated levels of PM2.5, hydrogen sulfide, and sulfur dioxide at the Liberty monitor.

By 8:20 a.m., the Allegheny County Health Department issued the following through the Allegheny Alert system and through social media:

An Air Pollution Warning has been issued for the Mon Valley for the remainder of today and all of tomorrow. The 24-hour PM2.5 standard for the Mon Valley has been exceeded at an official monitoring station in the Mon Valley and is likely to continue.

Young children, the elderly, and those with respiratory problems, such as asthma, emphysema, and bronchitis, are especially vulnerable to the effects of air pollution and should limit outdoor activities during this time.

Companies most significantly contributing to particulate pollution in the Mon Valley region are required to temporarily reduce particulate emissions.
