Work Detail

Environmental Services – Groundwater Remediation At The Former Darmstadt Gasworks. Execution Of A Pumping Test Lasting Several Weeks At A Groundwater Measuring Point In The Groundwater Outflow: - Construction Site Equipment (Setup Of Pumping Test Equipment, Installation Of Data Loggers In Monitoring Measuring Points), - Data Recording, - Gw Sampling, - Cleaning Of The Pumped Groundwater, - Introduction Of The Cleaned Groundwater Into The Public Sewer System, - Treatment And Provision Of Data, - Obtaining Approvals. There Is Groundwater Contamination In The Area Of ​​The Former Gasworks On Frankfurter Strasse In Darmstadt. Based On Soil And Groundwater Studies, A Complex Picture Of More Or Less Area-Wide, Partly Overlapping Contamination With The Pollutant Groups Btex Aromatics (Mainly Benzene), Pahs (Mainly Naphthalene) And Ammonium Was Identified For The Groundwater. The Damage Event Is Continuously Monitored As Part Of Semi-Annual Groundwater Monitoring. By Carrying Out A Pumping Test Lasting Several Weeks, The Development And Discharge Of Pollutants In The Tip Of The Pollutant Plume Should Be Examined And The Extent Of The Pollution In The Further Groundwater Outflow Can Therefore Be Assessed. Although The Estimate Of The Contract Value According To Section 3 Vgv Showed That The Contract Value Is Well Below The Threshold According To Section 106 Gwb And Below The De Minimis Limit According To Section 3 (9) Vgv, An Eu-Wide Procedure Is Chosen Because The Groundwater Remediation As A Whole Exceeds The Threshold Value § 106 Gwb For Services Exceeds.
