Odor Information

While odors are a natural and unavoidable byproduct of the decomposition of organic materials, the WPWMA endeavors to reduce the potential for the generation of odors from our facility. Staff continuously monitors facility operations and weather conditions in an effort to identify and minimize potential sources of odors.

The WPMWA employs an odor monitoring system designed to continuously measure specific odors and their intensities at four locations on the WPWMA’s property. Data from seven additional on-site and four off-site odor sources considered to have relatively consistent odor emission profiles are also included in the model, though these sources are estimated rather than measured. These data are coupled with on-site weather station data to generate air dispersion models of the measured and estimated odors.

The continuous odor monitoring system is used to assist in investigating reported odors, better understand the combination of operational and meteorological conditions that may result in odor impacts to the community, and to evaluate the relative effectiveness of specific odor reduction efforts. WPWMA staff conducts periodic odor monitoring on and offsite to augment and evaluate the continuous odor monitoring system.

The WPWMA also periodically employs an odor neutralizer to evaluate its effectiveness at reducing odors at various stages of the waste handling process.
