NEW: A 19-year study from the University of Arizona says biosolids pose little if any health risk to the public or the environment and are safe for agriculture. (pdf 205 KB)

A Virginia Department of Health study by three respected epidemiologists concluded that “… there does not seem to be strong evidence of serious health risks when biosolids are managed and monitored appropriately.” (pdf 201 KB)

An “Expert Panel” created by the Virginia General Assembly concluded that it had “…uncovered no evidence or literature verifying a causal link between biosolids and illness.” (pdf 786 KB)

A report by a team of researchers of national stature concluded: “To date, no case of pathogen-related”health effects from biosolids has been documented.” (pdf 102 KB)

Studies conducted at biosolids land application sites showed that endotoxin readings were well within recommended guidelines for occupational exposures. (pdf 688 KB)

A recent study demonstrated that many of the endotoxins released during land application were attributable to soil organisms, not to the biosolids alone. (pdf 311 KB)

Research showed that biosolids applied to soil caused the soil to be less prone to release of endotoxins to the air, because of the biosolids’ consistency and moisture. (pdf 881 KB)
