    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

    Floodwater samples (N = 110) collected during the 2011 Bangkok floods were tested for Leptospira using culture and polymerase chain reaction (PCR); 65 samples were PCR-positive for putatively non-pathogenic Leptospira species, 1 sample contained a putatively pathogenic Leptospira, and 6 samples contained Leptospira clustering phylogenetically with the intermediate group. The low prevalence of pathogenic and intermediate Leptospira in floodwater was consistent with the low number of human leptospirosis cases reported to the Bureau of Epidemiology in Thailand. This study provides baseline information on environmental Leptospira in Bangkok together with a set of laboratory tests that could be readily deployed in the event of future flooding
