Among the rivers tested, only the Netravati was rated B, making it suitable for bathing and domestic use. Eight rivers, including Lakshmanatirtha, Tungabhadra, Kaveri, Kabini, Krishna, and Shishila, were rated C, while three rivers, Bheema, Kaginah, and Arkavathi, received a D grade, indicating severe pollution.

The report highlights a serious environmental concern for Karnataka, where rivers are a primary source of water for millions. According to PCB officials, none of the rivers received an ‘A’ grade suitable for direct drinking. The study cites chemical contamination, oxygen depletion, and bacterial presence as major factors contributing to unsafe water quality.
