ABSTRACT This paper reports the results of a study conducted in Ban Nam Khem village, the most hit in Thailand by 2004 Indian Ocean tsunami, aimed to evaluate either the actual state and operation of numerous domestic wells present in the village or the quality of drawn groundwater. Data show that most critical chemical-physical parameters are turbidity, total organic carbon and iron, whereas conductivity has greatly decreased in comparison with the February 2005 monitoring campaign. Furthermore, a high faecal contamination related to both constructive and operational deficiencies was detected in most monitored wells; therefore, measures aimed at improving habits in well operation and favouring water domestic treatment are necessary.
