ABOUT
Starting in the fall of 2020, Murfreesboro Water Management created an air monitoring plan around the Middle Point Landfill, (MPL). The monitoring was limited to one type of gas, hydrogen sulfide. Hydrogen sulfide is found in both sewer gas and landfill gas. The results showed that the reported odor problems were caused by MPL, not by the City’s sewer structures or sewage pump stations.
How do we know? Here is one example: Two of the monitors registering high levels of hydrogen sulfide were near MPL. They recorded the highest levels of hydrogen sulfide when the wind was blowing across and off of the landfill. Those same monitors are not near any sewer infrastructure or pump stations.
Why is the City using this new odor reporting system? Two main reasons.
- The City was assured by Middle Point Landfill that landfill odors would stop at the end of July, 2021. The City has reason to believe the long-standing landfill odors have not stopped.
- The City recently learned that the Tennessee Department of Environment & Conservation (TDEC), which issues the permits for MPL, says that it has no authority (“no jurisdiction”) over odor issues. TDEC appears to lack the capacity to collect and keep detailed odor complaint information and take effective action.
