Groundwater monitoring at the Spechthausen landfill

Summary

The tender covers sampling and analysis of groundwater from three monitoring wells at the former Spechthausen landfill in autumn 2026. One well is upstream of the landfill and two are downstream. The work is to follow a review programme similar to the 2021 investigation and comply with the specified LAGA M 28 and LAWA methods and requirements. The work includes on-site measurements, recording measurement and analysis data during sampling, preparing a sampling record, laboratory analyses for parameter packages A and BÜ, and an investigation report. The report must compare results with LAWA insignificance thresholds and identify which parameters from package BÜ should be included in the standard package BS for subsequent years. Results and data must be delivered in two paper copies and digitally as a PDF. The work must be completed by 31 December 2026.
