Evaluation of drinking water quality in Tiruchirapalli, Tamil Nadu.

To evaluate the quality of drinking water in and around Tiruchirappalli City, twenty spots were identified within a radius of about 20 km. In all places ground water is used for drinking and domestic purposes. Nearly twenty physicochemical parameters were studied and the results have been presented. All the water bodies are found to contain high level of inorganic salts and total hardness with high electrical conductance. Since they are unsuitable for drinking purposes, method to improve the water quality has been suggested.
