美媒：氨含量过高，新德里深陷水污染危机

Core Viewpoint - Millions of residents in New Delhi are facing a severe water pollution crisis due to a sharp increase in ammonia levels in the Yamuna River, leading to the shutdown of six out of nine major water treatment plants and intermittent water shortages across the capital [1][2]. Group 1: Water Supply Crisis - Approximately 2 million residents in 43 communities are experiencing varying degrees of water shortages, with reports of water being available only every three days in some areas [1][2]. - Residents are relying on stored water or purchasing bottled water, as municipal water supply is deemed unreliable and often contaminated [2]. Group 2: Pollution Sources - The ammonia contamination is linked to long-term pollution of the Yamuna River, exacerbated by industrial waste and untreated sewage discharge, with New Delhi contributing approximately 76% of the river's pollution despite only 2% of its length flowing through the city [2]. - Factors contributing to the water crisis include reduced winter flow in the Yamuna, the closure of the Munak Canal for maintenance, and the lack of specialized ammonia removal facilities at the Wazirabad water treatment plant [2]. Group 3: Community Response - Local residents express concern that the water pollution crisis may become a regular occurrence, with no effective solutions provided by municipal authorities [3].
