2019 Residuals & Biosolids Seminar



2019 Residuals & Biosolids Seminar

WEAO’s Residual and Biosolids Committee is bringing a series of presentations and panel discussions to provide a regulatory and research update on various emerging substances in residuals and biosolids on Dec 4, 2019. As the presence of persistent organic pollutants such as Polyfluoroalkyl Substances (PFAS) and microplastics in biosolids is becoming a concern, this seminar aims to share the latest findings and studies from government and research institutes to educate the WEAO community about the new challenges and the path forward for the beneficial uses of biosolids
