Willowstick helps characterize potential groundwater pathways across a site, giving environmental teams a spatial framework for siting monitoring wells and testing a remediation concept. MM-ECD results are interpreted with direct water-level, water-quality, geology, and site-history data rather than used as a stand-alone plume map.

Environmental
Constrain potential groundwater transport pathways before committing to a remediation design.
The Problem
A remediation plan is only as strong as its conceptual site model.
Dissolved contaminant transport is influenced by groundwater gradients, hydraulic conductivity, geochemistry, and preferential pathways. Monitoring wells provide direct water-quality data at their locations; spatial geophysics can help identify connections between those points and improve the conceptual site model.

How Willowstick Maps It
The method, applied to environmental.
01
Establish a controlled circuit: electrodes are positioned so a signature alternating current passes through the area of interest. Its distribution responds to saturation, pore-water chemistry, clay and mineral content, geology, and other controls on bulk conductivity.
02
Measure the response: the Willowstick instrument records the resulting three-axis magnetic field at georeferenced stations on a surface grid. The magnetic survey does not replace sampling and does not directly measure contaminant concentration.
03
Model and interpret: measured data are normalized against a homogeneous-earth reference and processed into 2D and 3D electrical-current models. Monitoring, geology, and hydrology guide interpretation of potential hydraulic transport pathways.
04
Deliver reviewable targets: the report presents mapped anomalies, interpreted pathway targets, model-derived depth ranges where supported, and limitations for planning monitoring wells, sampling, or remediation.

Field acquisition is often completed in days and interpretation in weeks. Timing, depth of investigation, and deliverables are scoped to the site, method mix, and decision.
