Water Quality Monitoring of Pharmaceuticals and Personal Care Products Using Passive Samplers

Abstract:The demand on freshwater to sustain the needs of the growing population is of worldwide concern. Often this water is used, treated, and released for reuse by other communities. The anthropogenic contaminants present in this water may include complex mixtures of pesticides, prescription and nonprescription drugs, personal care and common consumer products, industrial and domestic-use materials and degradation products of these compounds. Although, the fate of these pharmaceuticals and personal care products (PPCPs) in wastewater treatment facilities is largely unknown, the limited data that does exist suggests that many of these chemicals survive treatment and some others are returned to their biologically active form via deconjugation of metabolites.

Traditional water sampling methods (i.e., grab or composite samples) often require the concentration of large amounts of water to detect trace levels of PPCPs. A passive sampler, the polar organic chemical integrative sampler (POCIS), has been developed to integratively concentrate the trace levels of these chemicals, determine the time-weighted average water concentrations, and provide a method of estimating the potential exposure of aquatic organisms to these complex mixtures of waterborne contaminants. The POCIS (U.S. Patent number 6,478,961) consists of a hydrophilic microporous membrane, acting as a semipermeable barrier, enveloping various solid-phase sorbents that retain the sampled chemicals. Sampling rates for individual chemicals determined in the laboratory are used in conjunction with theoretical uptake models to provide estimates of the ambient water concentrations of those chemicals.
