Groundwater Sampling

Millennium can provide you with various sampling and monitoring techniques for groundwater environments

Hydropunch sampling probe with a 4-foot stainless screen for discrete interval sampling
Installation of temporary and semi-permanent PVC screen casing through our probe rods for grab samples
Piezometer installation for measuring the changes in hydraulic head of groundwater in aquifers.
Dual Wall Sampling Probe for multi-saturated zone well instillations to eliminate the possibility of cross contamination between horizons.

For permanent well installation, we have the capability to direct drive 3/4-inch to 2 1/2-inch PVC equipped with pre-packed screens and quick seal, expanding foam bridges.
