The following leaching limit values apply for waste acceptable at landfills for inert waste, calculated at liquid to solid ratios (L/S) of 2 l/kg and 10 l/kg for total release and directly expressed in mg/l for C0 (the first eluate of percolation test at L/S = 0,1 l/kg). Member States shall determine which of the test methods (see section 3) and corresponding limit values in the table should be used.

In addition to the leaching limit values under section 2.1.2.1, inert wastes must meet the following additional limit values:
| Parameter | Value mg/kg |
|---|---|
| * In the case of soils, a higher limit value may be admitted by the competent authority, provided the DOC value of 500mg/kg is achieved at L/S = 10 l/kg, either at the soil's own pH or at a pH value between 7,5 and 8,0. | |

| BTEX (benzene, toluene, ethylbenzene and xylenes) | 6 |
| PCBs (polychlorinated biphenyls, 7 congeners) | 1 |
| Mineral oil (C10 to C40) | 500 |
| PAHs (polycyclic aromatic hydrocarbons) | Member States to set limit value |
