Abstract	Water contamination due to high levels of chloride, fluoride, and hardness poses a significant threat to public health and the environment. This study explores an eco-friendly treatment method using tamarind and neem as bio-adsorbents for the removal of these contaminants. Water samples were collected from Chittur, Kozhinjampara, Kollengode, and Pallassena in Palakkad, Kerala, India. The treatment process involved using neem and tamarind individually at varying concentrations (5, 10, 15, 20, and 25 mg/L for neem; 4, 8, 12, 16, and 20 mg/L for tamarind) and in combination at different ratios (1:1, 1:2, and 2:1). Experimental results indicated that neem at 10 mg/L, tamarind at 12 mg/L, and the combination of both in a 1:1 ratio achieved the highest removal efficiency for chloride, fluoride, and hardness. This study highlights the potential of tamarind and neem as sustainable and cost-effective alternatives for water treatment, offering an environmentally friendly solution for mitigating water contamination.
