A method is presented for using geoelectrical methods along with a supporting systems methodology to define aquifer and/or well head protection zones. The systems methodology utilizes geostatistics and multicriterion decision making (MCDM) to quantify the electrical measurements in terms of protection parameters and importantly to combine related and supporting measurement data with the electrical data. The protection properties of water table and leaky aquifers are defined in terms of electrical parameters. Geostatistics and MCDM are used to develop and apply (1) areal mapping procedures for the electrical measurements; (2) combining and mapping the electrical and other available data; (3) designing cost-effective measurement networks for geoelectric and combined measurements networks.
