Landfill Odor Update

September 22, 2025

In regards to the odor that arose last fall as the temperatures changed, we have, in collaboration with Jordan Disposal (the landfill operator), KDHE and the EPA, investigated ways to mitigate the nuisance that it has caused our community members. With that said, landfill operators have started applying layers of lime to the area on the landfill where the odor was detected from this past Spring. As per the studies and trials conducted, using lime amendment as a treatment for the mitigation of hydrogen sulfide (H2S) gas emissions have been successful. Once approval was received from KDHE for the use of lime, we then applied a significant quantity (over 100 tons) covering the area on top of the landfill that emits a detectable odor. The plan is to now monitor any reduction in detectable odor, and if effective, to continue layering with lime in any areas where odor is noticeable for the foreseeable future. Also note that while we may be able to smell the odor, it has yet to be detected at any harmful level and we are continuing to work closely with KDHE to ensure air monitoring protocols are being met for the safety of our citizens.

Evidence from other applications of lime, as well as lab testing shows that this is an effective treatment, however, we cannot be certain that this lime treatment will entirely remove the smell. We are optimistic that this will positively impact any smell that is coming from the landfill. Thank you for being understanding as we continue to pinpoint solutions to this issue.
