The health department is conducting a probe into alleged water contamination in Wazirabad near Sector 52, days after a four-year-old boy died.
Officials of the health department said they received 40 cases of diarrhoea last week, following the allegations of contamination.
Residents were advised to avoid consuming uncovered food and drinks, and boil potable water before drinking it.
“On Friday, five cases of diarrhoea were reported from the area.
These are in addition to 22 cases reported on Wednesday,” an official said.
Gurugram chief medical officer (CMO) Gulshan Rai Arora, said that water samples have been collected for testing.
“We are checking if there was a leak in the water supply pipeline, causing urea and other contaminants to be mixed with the water.
Another possible explanation can be inadequate chlorine in the water,” Arora said.
Yashpal Yadav, MCG commissioner, said, “The issue has not been brought to our notice yet.
No complaints have been registered in this regard.”
