Hello Nicolas. I have been part of a Tetrachloroethylene, PCE Superfund clean up site in New Mexico, USA. Early on we were able establish a nearly perfect (1.0) correlation curve of conductivity microsiemens to PCE concentration in parts per billion. This was a goundwater pump and treat so temperatures remained stable. SCADA was easily integrated with conductivity probes at both monitoring wells and the extraction wells. Periodic QA/QC checks to both the probes and the corralation curve has shown steady reliable measurement of PCE ppb monitoring in ground water and the PCE extracted as a function of conductivity probes. Give it a try.
If you want more of our information send me a note.
