Abstract Odours associated with hydrogen sulphide (H2S) have been a concern in the municipality of Sibate (Colombia) over the last decades. With the aim of determining the odour impact of Muna's reservoir, different H2S emission sources were evaluated and simulated. H2S surface emission rates from Muna's reservoir were estimated using the Flux Chamber experimental method. Meteorological conditions and emission rates were then fed to the AERMOD® model to identify the contribution of Muna's reservoir on H2S concentration in Sibate’s urban area. These results were compared and calibrated with real time H2S atmospheric concentration data. The average H2S emission rate was 1,886 μg/(min·m2), which primarily affects the municipality when wind direction is towards the south. The results of this study demonstrated the applicability of the AERMOD® model and flux chamber measurements in predicting H2S behaviour in the Sibate region.
