Identification of corrosivity ratio in the groundwater chemistry: A case study from Vaippar River Basin, Tamil Nadu

K.Sankar, K.Pandian

An attempt has been made to detect corrosivity ratio of groundwaters in the Vaippar River Basin by interpretation of fifty water samples during pre and post monsoon periods and it could be observed that the corrosivity ratio are found be more than fifty percentage in both seasons. In this study reveals that during the premonsoon period corrosivity ratio ranges from 0.06 -17.53 whereas post monsoon periods minimum are found to be 0.11 and maximumare exists 9.99. In this context, a study has been conducted to analyses various factors to involved abnormal ratio of corrosive tendencies. Further, the geological significance with reference to corrosivity ratio, geochemical characteristics of groundwater samples has also been interpreted.
