Distribution of Natural Organic Matter (NOM) in Full-scale Drinking Water Utilities of India in Eastern Region – Challenges and Issues

Natural organic matter (NOM) in the water supply system is a major source of concern. It degrades the quality of drinking water and causes the production of cancer-causing trihalomethane (THM) chemicals. The current study looked into the distribution of NOM species (TOC, DOC, UV254, and SUVA) and their problems in full-scale drinking water utility treatment stages. Raw water met the Bureau of Indian Standards in terms of physico-chemical parameters (BIS). During the monitoring process, TOC was discovered to be the most prevalent percentage of NOM, having a significant impact on treatment efficiency. The highest TOC concentration (3.8 mg/l) was found in VWTP’s raw water. The study will be of great assistance to the water management body in producing safe drinking water in the case of NOM.
