This article discusses the occurrence of endocrine disruptors, pharmaceuticals, and personal care products in surface water supplies, and how water utilities can reduce these compounds in drinking water by understanding upstream wastewater treatment processes. The effectiveness of advanced treatment processes in removing these compounds in secondary effluent is beneficial in demonstrating treatment performance. The article provides three examples of recent projects evaluating various treatment processes in preventing the passage of the compounds into water supplies. The treatment processes include: solids retention time (SRT) of the activated sludge process; wastewater granular media filters and microfiltration/reverse osmosis (MF/RO); pilot membrane bioreactor; and, ultraviolet (UV)/peroxide treatment as an additional barrier in RO‐treated tertiary wastewater effluent. The article offers important treatment suggestions, along with a sidebar that offers suggestions on relating information to customers on this topic.
