  1. WQCs are based on certain combinations of average conductivity and the variation between consecutive conductivity measurements, or fluctuation events, over a 3-h interval containing a total of 180 measurements. A fluctuation event was defined to happen when conductivity changed by more than 5 µScm−1 in 60 s
