Jacksonville Urban Odor Study

Project Description

The Environmental Quality Division (EQD) has been investigating “chemical-like” odors in some areas after multiple resident complaints over an extended period of time.  EQD currently uses traditional methods for odor assessment which consist of sending an inspector to assess the odor once a complaint comes in and determine if they perceive an odor or not. Although having been successfully used for years, the method has proven to be inefficient at times due to the rapid change in weather conditions that might cause an odor disturbance at the time of the complaint but when acted upon, the odor has shifted paths. Additionally, without having 24/7 continuous monitoring, there is currently no method in handling complaints efficiently and accurately outside of normal work hours. 

Project Goals

A 12-month study is proposed to inform the methods the city takes to handle odor complaints and accurately determine odor sources.  The information gathered will provide valued feedback to both EQD and the JEPB.

How You Can Help

While the installed equipment will work independently, it will help our staff if residents continue to let us know of if they experience unpleasant odors.  Everyone is encouraged to continue to call 630-CITY (2489) to register a complaint.  You can also submit a complaint electronically at www.myjax.custhelp.com.  Information received regarding complaints will be investigated using our normal processes.  We will, however, also use the information to validate the reports and information recieved from the equipment installed for the study.
