Roberto,
We use tritium analysis regularly for landfill monitoring, but
unfortunately most of that work is confidential and is not published.
Most (but not all) municipal landfills do have elevated tritium levels
due to the disposal of items with luminous paints.  For example, Swiss
Army watches have tritium dials and there is enough tritium in just one
watch (if that tritium were dispersed), to significantly increase the
tritium content of an entire landfill. I am not aware of any recent
publications on the subject but I do have a couple of older publications
that I will send you off-list.

Subject: [ISOGEOCHEM] Tritium in landfill percolating water

I have been requested by a colleague to provide a list of references on
the
isotopic composition of water percolating through landfill sites, and in
particular on its tritium content. I would appreciate if the Isogeochem
friends would help me by providing the title of recent publications in
that
field.
