Abstract-The increase in agricultural production, urbanization and rapid growth of population has led to fresh water shortage in several parts of the Cuddalore and Villupuram districts. Therefore making of quantitative estimation of the available groundwater resources is imperative in these districts. In this study, the Lower Ponnaiyar Sub-watershed is considered as a study area for evaluation of groundwater resources using Groundwater Estimation Committee – 1997 (GEC-1997). The various factors are involved in groundwater resource estimation such as recharge from rainfall, recharge from other sources and groundwater draft in both monsoon seasons. The groundwater utilization is estimated based on the Water Table Fluctuation (WTF) in the monsoon season and by rainfall infiltration factor method (RIF) in the non-monsoon season. The Results showed that the categorization of blocks in the study area such as Safe (Mugaiyur, T.V. Nallur, Annagramam and Bahour), Critical (Kandamangalam) and Over Exploited (Kanai, Kolianur and Cuddalore). This study was suggested; for implementation of appropriate management practices which would be improve the groundwater resources of the study area.
