Environmental information K20 - Exhaust air and groundwater purification

The contaminated site K20 in Br├╝ckl was secured in 2018 according to the current state of the art and sealed against air and groundwater. The exhaust air on the surface as well as the groundwater pumped out inside the sealing walls are cleaned with an activated carbon filter. The purified groundwater is returned to the groundwater outside of the sealing walls by means of swirling wells. Here you will find the values for exhaust air and groundwater in percent within the valid limit value.
