Germany – Engineering services – Stickstoff-/Argon-Untersuchungen an Grundwassermessstellen - Untersuchungen in 2027 sowie optional in 2028 und 2029

Due to current legal requirements of the Groundwater Ordinance (GrwV) and the General Administrative Regulation on the Designation of Nitrate-Contaminated and Eutrophic Areas (AVV GeA), the consideration of denitrification, including the determination of nitrate input concentration into groundwater, is playing an increasingly important role in water monitoring in Saxony-Anhalt. Therefore, N2-Ar analytics using Membrane Inlet Mass Spectrometry (MIMS method) is to be carried out on 500 groundwater samples to determine the current denitrification in the groundwater in the state of Saxony-Anhalt in 2027, with an option to do so in two subsequent years. The analysis results are to be evaluated and interpreted and documented in a final report.
