Odor and Air Quality Committee

The Odor and Air Quality Committee (OAQC) develops, recommends, supports, and conducts programs to promote the overall understanding of odor control and air quality issues as well as the control of corrosion issues at treatment plants and in the collection system.

We have developed and sponsored workshops at the Annual Conference, presented webinars focused on odor and air quality, and conducted a survey in August of 2015 to gather data on odor control technologies used by PNCWA members. We are presently working to develop a webinar on odor control in the PNCWA region for presentation in the spring of 2017 (ahead of the odor season), as well as a potential workshop on odor control monitoring, measurement and modeling for the 2017 Annual Conference

We hold regular monthly calls and an in-person meeting each year at the Annual Conference.

"Best of all, this next conference will be in Portland, making it easier for our PNCWA members to attend and giving us an opportunity to showcase the contribution of our association to the WEF community."

PNCWA Members Surveyed on Odor Control Technologies

The OAQ Committee has developed and distributed a survey to PNCWA members to identify odor control technologies currently in use in the region.  Responses have been received from 45 respondents and they are currently being tabulated.  We will be developing an article for the PNCWA Newsletter summarizing the survey results and are planning to provide the detailed results on our webpage.  One of the goals is to make the data available in such a form that PNCWA members can see who is currently using each technology and, for those respondents who are willing, contact the users to get specific information on their experiences and recommendations.
