Love My Air Program


The Jefferson County Love My Air program (JLMA) creates local capacity for underserved communities to monitor and address the air within our county.  The JLMA program will further support our communities through outreach and education efforts. The JLMA program is a partnership between Jefferson County Public Health and community-based organizations to extend Denver’s highly successful Love My Air Program. The program places low-cost, high-quality monitoring equipment at partner sites to provide real-time, particulate matter measurements on easy-to-understand, public-facing dashboards.

Smoking Vehicle Hotline Program

The Colorado Department of Public Health and Environment maintains the smoking vehicle hotline program [external link], which is designed to identify smoking vehicles and encourages owners to voluntarily make necessary repairs. The hotline provides motorists and others the opportunity to report smoking vehicles to the state Air Pollution Control Division by phone or email.
