In the last days of November I went to help my colleague (Botond Pap) in a research project in Bihor county. Because I was heading to that area, I proposed to collect spring water samples from Bihor county, in order to evaluate the dissolved methane content of the waters.
A spring near the road on the way to Damis village.
The autumn forest in Bihor county.
A spring congaing H2S (visible on the pipes interior).
A spring from Baile Tinca.
Putting in the last sample.:)
