Division 2.3.1 Leaching limit values
United Kingdom
The following leaching limit values apply to granular hazardous waste acceptable at landfills for non-hazardous waste, calculated at L/S = 2 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). Granular wastes include all wastes that are not monolithic. F1The appropriate authority shall determine which of the test methods and corresponding limit values should be used.
| Components | L/S = 2 l/kg | L/S = 10 l/kg | C0 (percolation test) |
|---|---|---|---|
| mg/kg dry substance | mg/kg dry substance | mg/l | |
* If the waste does not meet these values for DOC at its own pH, it may alternatively be tested at L/S = 10 l/kg and a pH of 7,5-8,0. The waste may be considered as complying with the acceptance criteria for DOC, if the result of this determination does not exceed 800 mg/kg (A draft method based on prEN 14429 is available). ** The values for TDS can be used alternativelyto the values for sulphate and chloride. | |||

F2The appropriate authority shall set criteria for monolithic waste to provide the same level of environmental protection given by the above limit values.
