Reddy, Dr. T. Srinivasa and Manasa, B. (2024) Finding Heavy Metals in Drinking Water Along the Krishna River. International Journal of Innovative Science and Research Technology, 10 (6): 25jun1295. pp. 2039-2045. ISSN 2456-2165
Access to clean and safe drinking water remains a critical concern in many developing regions, including parts of India. The Krishna River, a major water source in Andhra Pradesh, supports domestic, agricultural, and industrial activ- ities. However, increasing anthropogenic influences have raised concerns over the presence of heavy metal contaminants in its water. This study aims to assess the concentration of heavy metals such as Lead (Pb), Cadmium (Cd), Chromium (Cr), and Arsenic (As) in drinking water samples collected from various locations along the Krishna River. Standard analytical techniques, including Atomic Absorption Spectroscopy (AAS), were employed for metal detection. The results were compared with permissible limits set by the World Health Organization (WHO) and the Bureau of Indian Standards (BIS). Findings indicate the presence of potentially harmful concentrations of certain metals at specific sites, highlighting the urgent need for monitoring and remediation efforts. This research contributes to the understanding of regional water quality and supports policy recommendations for sustainable water management in Andhra Pradesh.
