Darold has been involved with tribal air quality monitoring since 2014. He transitioned over to environmental science with Pala after working many years in information systems and technical support. Pala's environmental department started the air quality monitoring program over 20 years ago. The location of tribal reservation is a hot spot for a few ambient air quality issues. Darold has made many needed changes and improvements to the program and continues to help the tribe expand it abilities to handle its AQI issues. He says after been introduced to this field of work and meeting all the wonderful people that helped him when he started, he feels in debt and enjoys paying it forward.
