Event recap
Under glorious late-summer skies on 4 September 2025, our team joined the 32nd Altlastentag Hannover. Colleagues from M&P Ingenieurgesellschaft Nord Hannover – part of SIERA took part across multiple workshops and activities throughout the day.
A special highlight was the new hands-on Field Work session, moderated by Lea Dreier and co-designed by colleagues Mahir Dinç and Felix Conradt. In small groups on the Suderburg campus, participants practiced small ram drilling, soil description, sampling, and soil-gas probing—directly in the field. Feedback was highly positive, and we’re excited to build on this momentum.
Connecting with the community
Just outside the plenary, our outdoor booth once again became a popular gathering point to network, exchange ideas, and—yes—soak up the sunshine. Visitors could also try their hand at estimating foreign material content, with surprisingly eye-opening results.
What we practiced in the “Field Work” session
Before we dive into the list, here is why these techniques matter. Each method helps us characterize subsurface conditions efficiently and safely, supporting land recycling and remediation concepts that protect people and groundwater. That’s central to how M&P Ingenieurgesellschaft Nord Hannover delivers value on contaminated-site projects.
- Small ram drilling
- Soil description
- Sampling strategies
- Soil-gas probing on site at Suderburg campus
