Core Competency

Environmental Monitoring

Underground work and pipelines live in an environmental context that has to be measured, not assumed — water tables, ground gases, and conductivity contrasts that signal leaks before they surface.

Detail

In practice

Groundwater monitoring

Piezometer networks, transducer data, and manual dips together describe how the groundwater system responds to construction dewatering, rainfall, and seasonal change. On the Lower Meramec Tunnel I processed groundwater datasets that supported field decision-making and reporting.

Methane & H₂S monitoring

In confined and tunnel environments, real-time gas monitoring (CH₄, H₂S, CO, O₂) is non-negotiable. I work with calibration logs, alarm thresholds, and ventilation responses so the data behind a green light is actually trustworthy.

Electrical Resistivity Tomography (ERT)

ERT images the subsurface by measuring how resistivity changes with depth and lateral position. Leaking pipelines often produce a measurable resistivity contrast against background soils. My SIUE graduate research applies ERT for subsurface investigation and detection of leaking pipelines, paired with PSD, Atterberg limit, and Proctor testing on representative soils.
