The ground water in the catchment areas of the Gomti river here has been found to be "highly contaminated" with cadmium, nitrite and lead concentrations, claims a report. Water samples collected from the community hand pump installed in Khadra, Deen dayal Nagar and Patanala areas in old city showed high concentrations of cadmium, lead and nitrite, much above the permissible level, says the report by Dr M C Saxena, director, Environmental Research Laboratory(ERL), a Government of India lab.
