METHOD
•   The soil attributes and the corresponding weights used for calculating the vulnerability index for pollution by leaching (groundwater / aquifers) are:
•Wet front hydraulic conductivity (derived pedotransfer function). For values greater than 10 mm h-1 the corresponding weight is “1”, for values in the range 4 – 10 mm h-1 the weight is “0.5”.
•Maximum available water (derived pedo-transfer function). For values less than 10 cm the weight is “1”.
