Abstract: Human survival largely depends on the quality of drinking water available. It is worth of knowing that drinking water from any source also contains many trace elements. The present study was carried out with the aim to assess of water quality using physico-chemical parameters of three well water samples (Srirengapuram (s1), Thadicheri (s2) & Nagalapuram (s3)) and three Falls water samples (Suruli Falls (s4), Mavoothu Falls (s5) Theertha Thotti Falls (s6)) collected from then district during the study period July-August 2007. The water quality parameters like Colour, Odour, PH, Turbidity, Fluoride, Chloride, Nitrite, Nitrate, Sulphate, Phosphate, Iron, Calcium, Magnesium, Hardness, etc. has been investigated. From the present investigation Srirengapuram well water (S1) sample is not potable due to excessive amount TDS (1350 mg/1 & 3675 mg/l), TH (1900 mg/l &2000 mg/l), EC (3550 & 5250 micro mho/cm) and chloride (1470 mg/l & 1500 mg/l) and Suruli falls water (S4) is not potable in the month of August due to excessive Turbidity (200 NTU) and iron content (2mg/l). The water qualities were estimated through physical and chemical parameters states that most of the water quality parameters were found well within the permissible limit as prescribed by ISI, ICMR and WHO except sample 1 and 4.
