Pharmaceuticals and Personal Care Products as Emerging Contaminants of Concern in Municipal Wastewater

Description:Pharmaceuticals and personal care products as emerging contaminants of concern in municipal wastewater. Presenter: Kevin Barnard, M.Sc., Capital Regional District. It is estimated that approximately six million Pharmaceuticals and Personal Care Products (PPCPs) exist worldwide. PPCPs are being detected in municipal wastewater, and becoming sources of concern among policy makers and the public. As a Regional Source Control Program inspector for the Capital Regional District, I regulate industrial, commercial, and institutional facilities to reduce contaminant loading into the wastewater systems and receiving environments. The Program also promotes reduced contaminant loadings through residential outreach and education. Part of the Regional Source Control Program’s initiative is dedicated to conducting research into emerging contaminants of concern. Graduate and undergraduate sponsored studies have: identified 125 PPCPs within the region’s wastewater; compared PPCP influent to effluent concentrations and loadings following preliminary treatment in the region; and estimated partitioning and environmental risk of PPCPs following secondary treatment in the region. My own Masters research conducted a comparative assessment of known partitioned PPCP loadings against modeled/predicted loadings to determine the effectiveness of estimation models for determining PPCP partitioning in wastewater systems; and conducted a comparative assessment of known PPCP concentrations in the region’s marine and terrestrial receiving environments against modeled/predicted toxicity values for aquatic and terrestrial species to determine priority PPCPs of concern. These studies further the characterization of the region’s wastewater contaminant inputs and outputs into the receiving environments, assist the CRD in developing policy on wastewater treatment systems and issues such as biosolids end-use, identify contaminants of concern such as Triclosan for risk management, and promote source control initiatives such as the Medication Return Program.
