Abstract :

A survey was conducted in rural and urban areas of district Ludhiana, Punjab (India) to find out the current status of water borne protozoans (Giardia and Cryptosporodium) and their incidence in relation to faecal indi –cator microbial agents (coliforms and Clostridium) in drinking water. In total 100 water samples were collected from various sources like submersible pumps, handpumps, municipal corporation taps and water filters. Giardia was not detected from any of the collected water samples. Results indicated incidence of Cryptosporodium, coliforms and Clostridium in water samples collected from handpump > submersible pumps and municipal corporation taps > water filters. Correlation of Cryptosporodium with Clostridium was also higher in handpump water followed by submersible pumps, while its correlation with coliforms was higher in submersible pumps and similar in water samples collected from other sources.
