Flow Control And Monitoring

Affordable, fast method sought for low-level organics monitoringProblem: Organic contaminates cause ecological problems at low concentrations that are expensive to investigate. The State of Washington has legacy PCBs and PBDEs in the Spokane River. Contaminates of emerging concern are also expensive to investigate. The USGS sought alternative methods to produce quantitative results.Solution: The Washington Department of Ecology (DOE) used the C.L.A.M. (Continuous Low-Level Aquatic Monitor) from C.I.Agent Storm-Water Solutions to field extract high volumes of water for inexpensive analysis of organics at low concentrations. The USGS compared the C.L.A.M. to the POCIS passive sampler and filtered grab samples for
