• The soil attributes and the corresponding
weights used for calculating the vulnerability index for pollution by runoff
(surface waters) are:
•Soil type. For “Lithosol”, “Andosol”, “Glacier”, “Rock Outcrop”
the weight is “1”.
•Presence of an
impermeable layer within the
soil profile. If the impermeable layer is within 0-40 cm than the
corresponding weight is “1”.
