Stjepan and Ecolog:
I'd be interested in all responses to this enquiry.
Forestry Suppliers (USA) used to sell (and probably still does) a
large-diameter (4-6 inches or a decimeter or so) hand-boring tool that
worked well for me in floodplain silts and sands, cutting through roots and
large stones, however, might be problematic. I have drilled as deeply as 20
feet, so 5 meters should be no problem. One could probably drill a bit
deeper, the main restriction being the weight of the tool. This method is
much cheaper than motor-driven units, and better than many of them. If
you've got a lot of holes to drill, you may want a motorized unit, but I
have found most regular augers unsatisfactory unless they're truck-mounted,
thus very expensive. The unit I used had different bit designs for different
soils, and the bits made all the difference. If you have any difficulty
finding the unit, I will be happy to search out more information for you if
you are interested.

Subject: [ECOLOG-L] groundwater level, temperature and eletrical
conductivity
Dear Ecologgers,
I would like to hear from those of you with experience with groundwater
monitoring.
I have to install three groundwater monitoring wells up to the depth of 5
meters in a floodplain forest in Istria, Croatia. I have to record
groundwater level, temperature and electrical conductivity on hourly
resolution.
Can you help me identify the best (quality/price) automated groundwater
monitoring devices. I could also use your experience on how to proprely bore
the well and install the equipment.
Thank you, and everything best to all of you in 2013.
