Increased inflow of water at Asse bore hole

At an Asse bore hole in a depth between 637 and 658 metres, the inflow of uncontaminated saline water increased to about 600 litres per day in the past days. The saline water is an uncontaminated brine entering from the groundwater.

Since Wednesday, 14 November 2012, its volume has increased from 50 to 615 litres per day. It is being observed whether the volume of influent brine increases further. In the past 24 hours, however, the volume has not increased any further.

At the actual main point of inflow in a depth of 658 metres, about 10,500 litres of uncontaminated saline water are collected daily.

Variations of influent volumes are not unusual in mines and may be caused by movements in the rock. As a result of the increase, the influent water is monitored even more intensely. In the process of monitoring it has shown that the saturation of the water has remained unchanged.

The BfS has informed the State Mining Authority and the Federal Environment Ministry as the supervisory authorities about the development.
