Abstract
ABSTRACT
The use of DRASTIC – an aquifer vulnerability to contamination assessment
tool, is analysed and reviewed for its applicability in helping develop a
national aquifer management systems from the vulnerability maps produced
by DRASTIC. Furthermore, the use of DRASTIC in assessing the vulnerability
of an aquifer on a localised scale has been performed. The study showed that
DRASTIC yields accurate results on localised scales where sufficient
information is available. The use of DRASTIC on a national scale is subject to
the scale of the input data and will only produce an aquifer vulnerability map
that may be used as a general national development tool that cannot be
applied to site specific developments.
