Water is an important component of living organisms, especially for human beings. The current study of Chemberambakkam lake gave a lot of information about quality of the drinking water. The present paper showed the concentration of trace elements (Cd, Cr, Pb, Fe, Mn, Co, Ni, Zn, Cu) and cations like (Na, K, Ca, Mg) in the Lake water of the Chemberambakkam. The heavy metal concentration of Cd, Pb, Fe, co, and Ni were observed in high concentration than the WHO recommend level in the water, it means the Chemberambakkam lake water is highly contaminated from its surrounding industries. The analysis of date gave normal concentration of cations.
