- Abstract
- The risk characterisation of quality and availability degradation of groundwater resources
has been pursued for a wide coastal plain (Metaponto plain, Italy), an area
covering 40 km along the Ionian Sea and 10 km inland. The quality degradation is
due two phenomena: pollution due to discharge of waste water (coming from urban
areas) and due to salt pollution, related to seawater intrusion but not only. The availability
decrease is due to overexploitation but also due to drought effects. Data of
1,130 wells have been collected. Wells, homogenously distributed in the area, were
the source of geological, stratigraphical, hydrogeological, geochemical data. In order
to manage space-related information via a GIS, a database system has been devised
to encompass all the surveyed wells and the body of information available per well.
Geo-databases were designed to comprise the tree types of data collected: a database
including geological and hydrogeological data (HDB), a database devoted to chemical
and physical data on groundwater (CDB), and a database including the geotechnical
parameters (GDB). The record pertaining to each well is identified in these databases
by the progressive number of the well itself. Every database is designed as follows:
a) the HDB contains 1,158 records, 28 of and 31 fields, mainly describing the geometry
of the well and of the stratigraphy; b) the CDB encompasses data about 157
wells, based on which the chemical and physical analyses of groundwater have been
carried out. More than one record has been associated with thes 157 wells, due to
periodic monitoring and analysis; c) the GDB covers 61 wells to which the geotechnical
parameters are referred. Each well is ascribed a set of geotechnical data which
have been yielded by soil samples taken at various depths. Based on geo-databases,
the geostatistical processing of data has permitted to characterise the degradation risk
of groundwater resources of a wide coastal aquifer. (literal)
