摘要：Wastewater and groundwater samples of Sanganer were studied to find out the pollution load of wastewater generated from dyeing and printing units and its impact on the quality of domestic wastewater of the Amanishah Nallah and groundwater. The wastewater of these units was found to have high concentrations of sodium, chloride, and sulfate. It has remarkable concentrations of copper, chromium, and iron with low chemical oxygen demand and nearly 7-fold biochemical oxygen demand. The wastewater of these units, discharged on land without any treatment, comes into the Amanishah Nallah through small watercourses. The quality of the domestic wastewater of Nallah deteriorates with the mixing of wastewater from these units. Maximum concentrations of physicochemical parameters were found at the Sanganer Road bridge sampling point. Eleven groundwater samples, collected from various locations of Sanganer, were found polluted due to percolation of wastewater into the ground. Copper and chromium were recorded from some groundwater sources while iron was recorded from almost all sources. Sodium and chloride are the major cation and anion in the groundwater, which is identical to the wastewater of dyeing and printing units. Source G5 , near the small watercourse carrying the wastewater of these units, had maximum impact and maximum values of physicochemical parameters.
