Non-Invasive Characterisation of NAPL-Contaminated Land by Spectral Induced Polarisation (SIP) Tomography
The main aims of this project are to:
The project comprises five main work packages, each of which is subdivided into specific tasks as follows:
Work package 1: Laboratory characterisation of NAPL-contaminated and clean samples to relate SIP phase spectra to known chemical, mineralogical and pore-fluid properties
Task 1: Petrophysical and mineralogical characterisation.
Task 2: Chemical analysis of contaminated samples.
Task 3: Measurement of the SIP spectra of the samples.
Work package 2: Model tank/column experiments using controlled releases of NAPLs to correlate SIP spectra and images against known geometries, media properties, flow-paths and hydraulic parameters
Task 4: Controlled release of NAPLs.
Work package 3: Development and testing of 2.5D numerical inversion software
Task 5: Development of 2.5D forward modelling scheme for full SIP frequency bandwidth.
Task 6: Development of 2.5D inversion software.
Work package 4: Field trials at industrial sites to validate laboratory and interpretive criteria
Task 7: Trial surveys undertaken in the West Midlands conurbations, much of which are underlain by Triassic sandstone.
Work package 5: Project management
Task 8: Overall co-ordination of the principal research tasks, reports, maintaining schedules, budget control, QA and liaison with EPSRC by the British Geological Survey.

This project will develop SIP as a cost-effective, non-invasive geophysical scanning technique to map and monitor organic contaminant distributions. In addition, 2.5D code will be developed to cover the full SIP frequency range (mHz to kHz).
