The Delhi Pradesh Congress Committee (DPCC) claims 33 water samples from Delhi's treatment plants failed quality tests between December 11-18, 2025, alleging public health endangerment by the BJP-led government. DPCC chief Devender Yadav cited contamination issues in several localities and criticized the Delhi Jal Board's low percentage of globally certified water testing labs, contrasting it with other states. He also accused the government of ignoring National Green Tribunal orders regarding water quality complaints.
