In southeast Delhi, near the Delhi-Mumbai expressway, illegal denim dyeing units are contaminating local water bodies with toxic chemicals. These illicit operations, found in Meethapur village, use harmful substances for dyeing jeans that bypass industrial regulations, releasing untreated waste into the Yamuna River. Residents report health issues like itchy throats and burning eyes, and complain of the foul-smelling, contaminated water. Despite sporadic government action, these units persist, posing serious environmental and health risks as highlighted by activists and experts.
