Measurement locations PFOS — shallow, influenced

In this map you can see the measurement locations sampled by RIVM for the research into the derivation of the final background value PFAS in landbed. The map shows measurement values of PFOS in the top 20 cm of soil in potentially affected areas. Because the derivation of the final background values is based on the top layer of the uninfluenced soil, these measurements are not included in the derivation of the final background value.
