Analysis For Fluorescent Groundwater Tracer Dyes
     EWC maintains the most up-to-date analytical instrumentation that is available for the detection and quantification of the fluorescent tracer dyes used in groundwater work.  We routinely provide pectrofluorometric documentation of dye concentrations in groundwater at a part per trillion.  EWC staff can perform these analyses on water samples and dye detectors delivered to us.  In addition, we can provide assistance in designing and interpreting tracer studies and supply the tracers in appropriate quantities, the passive dye detectors, and sampling and monitoring equipment especially designed for detecting and quantifying tracer arrival times and concentrations.  This equipment includes dye-concentrating samplers, flow-through fluorometers, and self contained submersible fluorometers.
