Air Quality Program

The Air Pollution Program monitors air quality on the reservation. The CRST DENR has an air monitoring unit stationed at CRST DENR headquarters. Once a week, samples are collected from the air monitoring unit and sent to a laboratory for analysis. The results of the samples are used to create a trend analysis report that will aid in monitoring fluctuations in air quality levels.
