Trace organic compounds (TOrCs) in land-applied biosolids are of concern to the public, the water quality industry, and the regulatory community. The number of scientific studies examining the issue continues to grow, but significant knowledge gaps remain that hinder the water sector's ability to assess the risks TOrCs pose to human health and the environment. The focus of this research was to obtain high-quality data on the fate, exposure, and toxicity of the target TOrCs for use in assessing their risk. This goal was accomplished by either obtaining data from the literature or by direct measurement in laboratory studies and from field samples. An emphasis was placed on data generated in realistic biosolids-soil matrices, with realistic loading rates, and under real-world scenarios. Published in 2019.
