| This study investigated the occurrence of pharmaceuticals in biosolids, local biosolid-amended crop soils, and Fox River sediments located near the discharge points of Waukesha County wastewater treatment plants. Recent studies have verified the presence of pharmaceuticals in the wastewater influent and effluent; therefore it is likely they are accumulating in solids produced during treatment or from subsequent exposure to those solids or effluent. The biosolids have been anerobically digested and dewatered and are applied as an organic-rich amendment to local cropland soils. The river sediments are exposed to the treated effluent and were sampled above and below the discharge points to the river. The solids were liquid/solid extracted and cleaned up and concentrated using solid-phase-extraction. The extracts were then analyzed for acetaminophen, atorvastatin, carbamazepine, caffeine, cimetidine, diltiazem, fluoxetine, hydrocodone, and erythromycin using LC/MS analysis in MS (+1) mode. |
