Dutch Standards are environmental pollutant reference values used in environmental remediation, investigation and cleanup.^{[1] [2]}

The reference values for soil are adjusted for the organic matter (humus) content and soil fraction < 0.2 µm (lutum - Latin, meaning "mud" or "clay"). The values below are calculated for a 'Standard Soil' with 10% organic matter and 25% lutum.

The reference values for groundwater depend on the depth of the sample, the values below are for 'shallow' groundwater, 0 - 10 m depth.

A case of environmental contamination is defined as 'serious' if >25 m³ soil or >100 m³ groundwater is contaminated above the intervention value.
