Engineering services for monitoring, monitoring and documentation of stove remediation and the function of the bio-barrier.

The award takes place for the following services:

Engineering and expert appraisal services for truck groundwater remediation and groundwater monitoring on the site have been manufactured since the 1960s. A chrome factory was operated until 1969. On the site, subsoil contamination by LHKW (main pollutant tetrachlorethene) and Cr (VI) from 2 entry ranges are known. The remediation of groundwater has been carried out since 2010 through a three-part renovation concept. This consists of

1. Pump&Treat measures over 3 renovation wells with a total of approx. 4 m 3/h and reinfiltration in the inflow in 4 gulp wells for the rehabilitation of the damage detection including monthly. Plant monitoring

2. In situ biological pollutant degradation by establishing a Reducing Milieus as a “barrier” in the medial flag area for the rehabilitation of the pollutant plume and

3. regular monitoring to monitor the remediation.

— familiarization with the project,

— remediation monitoring (plant controls, groundwater monitoring in the source of damage, biobarrier, inflow, outflow and lateral flow),
