Phenols are toxic in nature .In present study the phenol contamination in ground water resources near Mahad MIDC area has beendetermined using calibration curve method spectrophotometrically. For that samples were collected from eleven different wells and analyzed. The results of all water samples show that observed phenol contamination is near about permissible limit. Throughout the year this water from all sampling sites can be used for domestic as well as irrigation purpose as contamination is within permissible limit.
