Abstract
The Triassic Sandstone is a major aquifer for western England and it has also historically been the location of much heavy industry. As industrial use of local groundwater recedes, water tables are rising and may remobilise contaminants held near the surface in the vadose zone. A robust method to survey for contaminants, and to be able to discriminate between different types, is desired. Measurements of Spectral Induced Polarization (SIP) is a potentially powerful discriminatory technique; however, before investigating the SIP properties of contaminated sandstone, it is important to understand the response of natural uncontaminated sandstones. This paper describes the use of SIP in field measurements on uncontaminated sandstones in various sites in the west of England.
