Finishing of deep borehole drilling campaign

Yesterday the deep borehole drilling campaign at the HOAL was finished. The groundwater layer was hit at almost all surveying gauges, at one location we drilled up to 41m to hit this layer. The gauges will now be equipped with serveral sensors for a continuous monitoring.

See some more impressions of the quite challenging - due to partly bad weather and other issues - campaign.
