A large number of coastal aquifers worldwide are impacted by seawater intrusion. A
major aim of European Directives 2000/60/EC and 2006/118/EC is to achieve good ecological
status in groundwater bodies, including coastal aquifers. To this goal, information is needed
about the current state of, and changes over time in, individual aquifers. This information can
be obtained by applying methods that determine the status of aquifers in an uncomplicated
manner. Methods for this type of assessment must comply with three essential criteria. First,
calculation of the index must be straightforward and should be based on easy-to-obtain or
commonly available data. Next, the index should be able to highlight important characteristics
in understandable terms. Finally, the results should be objective and should be expressed in
such a way that different time periods and different aquifers can be compared. In this paper we
describe the development of a method to characterize seawater intrusion that meets these
criteria and is based on four basic parameters: surface area, intensity, temporality, and
evolution. Each parameter is determined by specific calculations derived from the groundwater
chloride concentrations. Results are specified as a numerical index and an alphanumeric code.
This index, known as SITE, has been applied to four Mediterranean coastal aquifers. The
standardized results allowed us to discriminate between, and objectively compare the status of
these groundwater bodies. Further, this index will make it possible to prioritize management
actions and evaluate the effectiveness of these actions over time. [-]
