Box plots of experimental log KOC values for REACH registered substances reported in the Swiss or Dutch groundwater survey, grouped according to their persistency classification. See the SI for more information about the monitoring data. Also shown is the PMT/vPvM classification presented in 2019. Briefly, for persistent (P) and very persistent (vP) environmental half-life criteria established in REACH Annex XIII are used [61]; substances that meet the P or vP criterion can be considered "PM" if the minimum experimentally measured log Koc is < 4.0 (and therefore a PMT substance if additionally found to be toxic), and vP substances can be considered a vPvM substance if there is a minimum experimentally measured log Koc < 3.0 according to the currently proposed definition of PMT/vPvM substances [4]. The thresholds of log Koc < 4.0 (red line) and log Koc < 3.0 (dark red line) are presented
