EUGAL pipeline and local water quality

“GASCADE regrets the current water quality of the Schwarze Elster. But we see no connection between the construction of the EUGAL and the currently prevailing bad water quality in the Black Elster. All authorised discharge points are located approximately 20 km from the investigated areas of the Schwarze Elster near Bad Liebenwerda. v

“GASCADE sees the cause of the current water quality of the Schwarze Elster in the pre-stress of the old opencast mining in the region and the current drought. The pH values ??of the water in the soil, in the lakes and opencast mining holes and also in the receiving waters are already heavily polluted in the mining region. As early as 2017, very low pH levels were measured there – well before the construction of EUGAL.

“GASCADE 27 discharge points were approved in the Schwarze Elster region. Due to construction activities, we are currently introducing groundwater into the existing trench systems in three places. The pH value of the water introduced by us is between 6 and 6.9 – which is well above the values ??of the water in the existing trench system. Additional water is seeped into fields with the consent of the owners and thus returns to the groundwater.”

Background

GASCADE’s water discharges are all approved via the completed planning approval procedure. Each introduction is also submitted in an executive planning of the Upper Water Authority; The Upper Water Authority may, if necessary, issue further by-laws upon each initiation.

During pipeline construction, groundwater is pumped to keep the trench dry during construction. For this purpose, wells are drilled next to the trench. After filling the trench, this drainage is set again. Nothing is added to the groundwater produced in this way. The water is discharged via settling tanks, which filter out sand and clay either in trenches, or spread over large areas on agricultural land, where it seeps away again.
