McKenzie River, Oregon, Source Water Quality Protection

Data

Passive samplers—both semipermeable-membrane devices (SPMDs) and polar organic chemical integrative samplers (POCIS)—were deployed at three sites in the McKenzie River Basin on 9/11/2007 and retrieved on 10/16/2007. Analyses of the extracts from these samplers are provided here:

• Concentrations of select pesticides measured by polar organic chemical integrative samplers (POCIS)
• Concentrations of select wastewater-indicator chemicals measured by POCIS
• Concentrations of select wastewater-indicator chemicals measured by semipermeable membrane devices (SPMD)
• Concentrations of select polycyclic aromatic hydrocarbons measured by SPMD
• Concentrations of select organochlorine pesticides, total polychlorinated biphenyls (PCBs), and select polybrominated diphenyl ethers (PBDEs) measured by SPMD

Further information on SPMDs and POCIS is available through the USGS Columbia Environmental Research Center, where both samplers were developed:
