| Short Description |
A screening analysis was conducted for 24 pharmaceuticals and personal care products (PPCPs) in tertiary wastewater treatment plant effluents and nearby wells and creeks in the Sequim-Dungeness area of northwest Washington. The objective was to investigate the potential for PPCP contamination of area waters from application of treated wastewater via re-use programs and conventional land application. The following 16 compounds were detected in the effluent samples: Acetaminophen, Caffeine, Carbamazepine, Cimetidine, Codeine, Cotinine, Diltiazem, Hydrocodone, Ketoprofen, Metformin, Nicotine, Paraxanthine, Salbutamol, Sulfamethoxazole, Trimethoprim, and Estrone. Concentrations ranged from 0.26 ng/L (Estrone) to 200 ug/L (Paraxanthine). Only Caffeine, Nicotine, and the diabetes drug Metformin (tentatively identified) were consistently detected in the well and creek samples; concentrations were less than 25 ug/L.

| Abstract | Long Description |
A screening analysis was conducted for 24 pharmaceuticals and personal care products (PPCPs) in tertiary wastewater treatment plant effluents and nearby wells and creeks in the Sequim-Dungeness area of northwest Washington. The objective was to investigate the potential for and status of PPCP contamination of area waters from application of treated wastewater via re-use programs and conventional land application. A well located in an area served by on-site septic systems also was sampled. The following 16 compounds were detected in one or both effluents: Acetaminophen, Caffeine, Carbamazepine, Cimetidine, Codeine, Cotinine, Diltiazem, Hydrocodone, Ketoprofen, Metformin, Nicotine, Paraxanthine, Salbutamol, Sulfamethoxazole, Trimethoprim, and Estrone. Concentrations ranged from 0.26 ng/L (Estrone) to 200 ug/L (Paraxanthine). Only Caffeine, Nicotine, and the diabetes drug Metformin (tentatively identified) were consistently detected in the well and creek samples; concentrations were 25 ug/L or less. In at least some samples, Nicotine appeared to be an artifact of sampling handling procedures. These limited results give no indication that PPCPs represent a significant concern in the wells or creeks sampled. Additional monitoring for PPCPs appears to be a low priority in connection with the Sequim and Sunland wastewater treatment plants. |
