I couldn’t find anything suitable in the search. After the report from the municipality for the entire construction area showed a classification of Z 0 based on five boreholes, we received the report for our plot today, and it comes back with a classification of Z 1.1, with an elevated chromium level.
The following passage is included in the report regarding this value:
“In case of reuse of the material on local sites with similar geology and thus comparable background contamination, the chromium content found in mixed sample MP 1 does not represent an exclusion criterion. Use in the installation class Z 0 should be coordinated in advance with the relevant authorities.”
I couldn’t reach anyone this afternoon. Does anyone among the experienced forum members have an idea what this specifically means?
It looks like we’ll have some difficulties with our excavation material at certain disposal sites.
Does anyone have experience with the additional costs associated with this soil classification, or can they roughly estimate the difference in percentage compared to Z 0?
If so, what were your extra costs?
The property is located in Bavaria (Franconia).
And yes, I’m aware that this can vary from region to region and from one disposal site to another, but maybe someone still has some helpful experience to share.
Thanks

The Z classification is not related to landfill. The Z value indicates the level of recyclability. Up to and including Z2, bulk materials can be recycled.
The landfill regulations classify soil masses from DK 0 to DK 4.
It is best to contact a landfill or, even better, a recycling facility with the chemical analysis.
Prices vary widely depending on availability, ranging from 15€/ton (approximately 13.60 USD/ton) to 60€/ton (approximately 54.40 USD/ton).
Since your analysis shows Z1.1 and only one value is above Z0, you should not have any issues transporting this material to a recycling facility. These are usually old quarries or similar sites that are being refilled. Alternatively, check locally if someone might need soil masses.
