Abstract: The appropriate handling of stormwater samples is important to keep sample integrity and obtain representative results, as sample storage conditions may influence the changes in stormwater sample quality. However, the extent to which the storage temperature and time are reported in stormwater quality studies varies widely between studies. This study aimed to review stormwater sample handling with respect to storage temperature and time from sample collection, during transportation to the laboratory and until analysis. The results showed that 53% of the 375 reviewed articles failed to mention sample storage temperature and time from collection until analysis and 47% partially mentioned the storage conditions. Moreover, 74% and 72% of the 375 articles did not mention storage temperature from field to laboratory and from lab until analysis, respectively. The storage time from field to laboratory was not mentioned in 84% of the articles and storage time from laboratory until analysis was not mentioned in 79%. Among the studies that reported storage temperature of stormwater samples, the storage temperature ranged from -80°C to 25°C, while the sample storage time ranged from immediate analysis to 3 months of storage prior to analysis. The storage conditions were different depending on the parameters analyzed.
