Community Air Screen (CAS) Program

What is the CAS program?

This community-based program works with volunteers from local communities to screen for toxic air pollutants. The goal of the CAS program is for community groups and citizens to partner with DEC to collect local-scale air samples to address some local air quality concerns.

What's New?

DEC has released the 2017-18 CAS sampling results.

What's in the Report?

The reports detail how air samples are collected and the methods used to evaluate the sampling results. Technical appendices are included to provide additional information on controlling air pollution sources as well as the uses, sources, and potential exposure to air toxics measured in the CAS program. To learn more, read the reports and technical appendices.
