Research Highlight

Assessment of ionic species in rainwater during the summer monsoon season at three different locations in India

As a part of the IITM rainwater chemistry campaign, a study was conducted to investigate the rainwater chemistry at three different locations in India during the Southwest monsoon season from June to September 2018. The mean pH and conductivity exhibited significant heterogeneity among the rainwater samples, with alkaline characteristics observed at Jaipur (7.09 and 43.46 µS/cm) and Varanasi (7.31 and 55.42 µS/cm), whereas relatively acidic conditions were observed at Dhanbad (5.10 and 31.98 µS/cm). Moreover, the ionic composition of rainwater varied considerably across all three stations, which was clearly reflected in the rainwater neutralization characteristics. Calcium ion was identified as the major neutralizing species in rainwater at Jaipur and Varanasi, with high neutralization factors of 3.10 and 2.65, respectively, whereas such dominance was not evident at Dhanbad. The results suggest that contributions from both local and regional sources significantly influence the monsoonal rainwater chemistry over these regions.
