Summary

EcoImpact Solutions described an EPA-funded three-year tri-county air-quality project that adds low-cost PurpleAir sensors and mid-level QuantaQ monitors; a QuantaQ monitor was installed near Silverton School and 23 community sensors are available for checkout.

Emily Elias, founder of EcoImpact Solutions, told trustees on July 27 that a three-year EPA-funded Southwest Colorado air-quality project will expand monitoring and public outreach across Archuleta, La Plata and San Juan counties.

Elias said the project has three main objectives: increase monitoring coverage, improve public awareness of air-quality health risks and protective actions, and make data accessible to the Tri-County public through a project website (swcoair.org). The project includes a community checkout program for 23 low-cost PurpleAir sensors (15 have been checked out so far) and five mid-level QuantaQ modular sensors; EcoImpact just installed a QuantaQ sensor near Silverton School.

Elias explained the public-health context for particulate matter (PM2.5) and ground-level ozone and demonstrated how PurpleAir displays color-coded air-quality status that the public can view on maps. She invited community members to borrow sensors, attend an October webinar and sign up through the project’s QR code. Elias also suggested moving the school-area QuantaQ sensor from solar to wired power ahead of winter for reliability.
