Biosolids and Odor

Even those people who regard municipal biosolids as a wonderful resource would be hard pressed to classify their odor as innocuous. For those who question the safety of biosolids, their odor is proof that beneficial use of biosolids is an unsafe practice. There are two important aspects to this contentious issue, the particular aromas of biosolids. The first relates to how people perceive odors and the potential for bad odors to make people sick. The second relates to why biosolids can smell so bad and what can be done to make them smell better.
