"14,132 habitations are affected by contamination of fluoride and 1,991 habitations are affected by arsenic," Nadda said in Lok Sabha during Question Hour, citing information provided by the Ministry of Drinking Water and Sanitation.
Contaminated drinking water can cause various diseases such as cholera, typhoid and acute encephalitis syndrome.
Intake of fluoride and arsenic contaminated drinking water leads to various clinical complications and at times even cause death, the Minister said.
Nadda said "more intensive co-ordination is required" to tackle contamination of drinking water between the Ministries of Health and Drinking Water and Sanitation to ensure safe drinking water.
