A Geophysical Program was conducted at 5 groundwater monitoring wells on March 4, 2000 at the Faro Tailings Area, Yukon. The program used an EM39 instrument to measure electrical conductivity and a gamma probe to measure soil type changes, allowing for the identification of vertical zones affected by contaminant levels. The data was collected by EBA Engineering Consultants Ltd. under the auspices of Yukon Government, DIAND Mineral Resources, and Environment Canada.
Use Cases
- Identify vertical zones of soil contamination based on electrical conductivity anomalies.
- Distinguish between contaminant-induced conductivity changes and natural soil layer changes based on gamma probe readings.
- Model contaminant plume migration in groundwater based on conductivity profiles.
- Assess remediation effectiveness at mine tailings sites based on historical geophysical data.
Strengths
- Data was collected at 5 specific groundwater monitoring wells, providing discrete spatial points.
- The methodology uses two complementary probes (EM39 and gamma) to isolate contaminant effects from soil type changes.
- The probe specifications are detailed: 3.6 cm diameter, 1.6 m long, measuring conductivity within about 1 metre.
Limitations
- Row count and column-level documentation are absent; field semantics must be inferred after download.
- The dataset is from a single day (March 4, 2000), limiting temporal analysis.
- The data format is HTML/PDF, which may require extraction to a structured format for analysis.
