<p>The sugar industry substantially serves worldwide agriculture and economics and tends to flourish in areas where water resources are essential for both industrial activities and the environment. India is the country with the second-largest global sugar production in the year 2023–2024. Sugarcane requires a lot of water to grow, and the sugar industries utilize a huge water for sugar production. Also, the sugar factories generate a huge quantity of wastewater throughout the process. Therefore, this study is designed to monitor the groundwater quality in and around sugar factories and to produce detailed data for efficient groundwater utilization in sugar factories. This study also aims to understand the quality and groundwater variability both during and after the sugar-producing season. This is the first systematic research of its type to monitor the groundwater surrounding sugar industries in Northern India. For this study, three samples were collected from two factories, viz; Dalmia Bharat Sugar &amp; Industries Ltd., located at Jawaharpur and Ramgarh, Sitapur, Uttar Pradesh, India. One sample was taken inside the premises of the sugar factories, while the other two were taken at the of 1&#xa0;km and 3&#xa0;km, every month from July 2023 to June 2024. The samples were analyzed for pH, total dissolved solids, electrical conductivity, alkalinity, hardness, chloride, sulphate, nitrate, biochemical oxygen demand, chemical oxygen demand, and a few metals like Mn and Zn, and heavy metals such as Fe, Cu, Cr, and Pb, Cd. As per the study, the groundwater samples analyzed reveal that the groundwater in and around are good enough as the average levels of the parameters are under permissible limits of the World Health Organization and the Bureau of Indian Standards.</p>
