This document presents information about lead content in the Indian water system. It discusses what lead is, its effects, and how it enters the water system through various sources like oceans, rivers, tap water, and wells. It finds that lead levels in Indian water ranges from 50 to 400 μg/L. Several cities in India are at high risk of lead contamination in their water. Steps are recommended to reduce lead levels, including testing water, checking pH levels, and restricting pollution from industries and leaded gasoline. The conclusion is that human activities have contributed greatly to rising lead levels in water.
