CHALLENGES OF CHARACTERISATION AND TIME-LAPSE MONITORING OF SOIL CONTAMINATION, EXPERIENCE FROM THE SOILCAM PROJECT (EU)
The overall objective of the SoilCAM project was to determine necessary basis for designing an optimal combination of invasive and non-invasive methods for monitoring degradable contaminants in spatially variable soil systems. To achieve that, SoilCAM combined advanced conventional soil monitoring techniques with state-of-the-art geophysical approaches. These were interpreted individually and combined through pedotransfer functions. To integrate different pieces of information, i.e. the invasive and non-invasive field data and more detailed laboratory studies of microbial degradation processes and column experiments, numerical flow, transport and geo-chemical interaction models are used. Simulations were used to explore effects of different climatic conditions, sensitivity to geological conditions and presence of membranes in the ground on fate of contaminants.
SoilCAM activities were centred on two European field sites faced with contamination issues: Trecate in northern Italy affected by NAPL from an oil blow out in 1994, and Oslo airport, Gardermoen in southern Norway where large amounts of de-icing chemicals are supplied to the soil surface every winter.
