Estrogenic compounds may enter the environment when biosolids are applied to land. In the present study, soil samples were collected over 4 mo from a field trial following addition of biosolids. The recombinant yeast estrogen screen bioassay identified estrogenic activity in the soil at all sampling times to concentrations up to 2.3 µg 17β‐estradiol equivalency/kg. The present results indicate the potential for estrogenic compounds to persist in soil following biosolids application. Environ Toxicol Chem 2014;33:26–28. © 2013 SETAC
