Abstract. The objective of this study is to estimate Chloride of the groundwater in Chanthaburi, Thailand using multiple regression analysis. The multiple linear regression equation proposed in this study related to Chloride, Total dissolved solids, Iron, Nitrate and Total hardness data which are obtained from the Department of Groundwater Resources, Thailand. Results shows that the best fitted equation to estimate Chloride () of the groundwater in Chanthaburi relates to Total dissolved solids (
) and Total hardness (
). It can be estimated by

with adjusted coefficient of determination
