English Abstract On request of the Province of Overijssel the National
Institute of Public Health and Environmental Protection (RIVM) carried out
an investigation to: 1. A test method for industrial waste materials which
should be accepted at a dumping site and taking into account the influences
of the percolate that has been formed already by domestic waste
(co-disposal). 2. An acceptation procedure on the basis of a short test
method. 3. A list of components to be tested in this procedure. 4. A
list of concentration criterions in terms of leaching and composition of the
waste material. The RIVM started with a survey on waste materials which
have been frequently offered for dumping. In this study use was made of the
Standard Leaching Test (SLT). As leaching agent synthetic rainwater (SRW)
was used in order to simulate a mono-disposal of industrial waste and
synthetic dumping site percolation water (SPW) was applied with a view to
the behaviour of industrial wastes in co-disposal with domestic waste.
Fourteen industrial wastes were leached out. The percolates were analyzed
on the elements As, Cd, Cr, Cu, Hg, Pb, and Sb.
