The Brightwater Air Quality Advisory Board was formed to advise the county on any corrective actions necessary to achieve our commitment to no detectable odors at the property boundary of the Brightwater Treatment facilities or beyond.

The work and duties of the Board include:

  • Review odor monitoring data, and any complaints received, as described in the Brightwater Odor Monitoring and Response Plan.
  • Review investigations of odor complaints, including corrective actions taken.
  • If requested, provide recommendations for adjustment and improvements to the Brightwater odor control system.
