  • Choosing the Best Filter and Grout Materials for a Monitoring Well

    When it comes to site characterization, your monitoring well is only as reliable as the materials surrounding it. Choosing the right filter pack and grout isn’t just about “filling the hole”—it’s about ensuring hydraulic connectivity while preventing cross-contamination. Filter Pack 1. Filter Pack Material Selection The filter pack (or sand pack) acts as a mechanical…

  • Choosing the Best Screen and Riser Pipe Materials for Monitoring Wells

    In environmental monitoring, the integrity of your data depends on the “inertness” of your well materials. Screen and riser pipes serve as the structural skeleton of a monitoring well, and their chemical compatibility with local groundwater is paramount. Selecting the right materials ensures that your samples are representative of the actual subsurface conditions rather than…

  • Designing a Monitoring Well for Environmental and Geotechnical Investigations

    Designing a monitoring well involves a balance of technical requirements based on regulatory standards, the site’s hydrogeology, and the specific data objectives of the investigation (environmental or geotechnical). The design must ensure that the well provides a representative sample of the groundwater or an accurate measurement of the water level at the targeted depth. I.…
