Committee meeting
The special issues committee discusses odors at Mayfield Dairy and short term rentals on April 4.
As odor problems continue to plague West Homewood residents living near the Dean Foods/Mayfield Dairy plants, the city council recently hired an environmental consulting firm to help.
The firm, Volatile Analysis, has promised to determine the source of foul odors that have not diminished over the past several months, despite the plant replacing equipment and trying new techniques. The first step for Volatile Analysis is to try to identify a pattern for when the smell appears and is at its strongest.
To do this, the firm has distributed a questionnaire for West Homewood residents, the council and the plant owners to share their own experiences with the smell. The portion related to resident experience is below. If you have noticed the odor before, please fill out the below survey and send it to Ward 2 Representative Vance Moody, vance.moody@triconwearsolutions.com.
Moody said there is no deadline, but sooner is better as it will enable Volatile Analysis to begin their next steps more quickly.
