Deep blue green water, cold but refreshing in the hot sun. The water is blue green because of the limestone in the surrounding rock. It is also poisonous because of the lead (plumbum) and zinc that was the reason for opening the shaft. I told them that they will probably get rid of parasites of the skin and hair but that it is unwise to drink the water. This is the last and final report from professor Kill. 2nd of June 2010.
Keep cool and we will meet again !

Here is the group that has been in Finland as well as in Italy.

The last biology lesson of the year, the 2nd of June 2010. Investigating blue green water in an old mine. Summer has come. Only a few days till the final exam.
