Valley AIRNow is a community partnership of businesses, government agencies, and Frederick County citizens dedicated to preserving clean air — a staple of the Northern Shenandoah Valley.

Air quality alerts are available through the Department of Environmental Quality when ground-level ozone concentrations are forecast to be unhealthy for sensitive groups.

Remaining indoors in a cool place and taking steps to reduce car emissions are just two of the things you can do to help on alert days.
