A sudden green coloration of the water in Bhatghar Dam, located in Pune district, has sparked concern among local residents and authorities. The unusual change, visible especially in the morning hours till noon, has been observed along the northern banks and surrounding areas such as Sangamner, Malwadi, and Narhe villages.
Bhatghar Dam is a key drinking water source for several villages, including Bhor city. The unusual water color has raised questions about its safety for daily use.
What’s Causing the Green Water?
Local officials suspect the discoloration is due to an algae bloom, triggered by excess nitrogen in the water. This nitrogen is believed to come from private fish farming activities inside the dam.
“Fishermen sprinkle fish feed that is high in nitrogen. This excess nitrogen promotes algae growth, turning the water green,” said Vikash Kharat, Sub-Divisional Officer of Bhor.
He confirmed that water samples have been collected and sent for lab testing. Results are expected within two days.
Is the Water Safe?
According to Kharat:
“There is no cause for panic. This is a natural reaction to nutrient imbalance. No health issues have been reported so far, and the water remains safe to consume.”
However, as a precautionary step, the administration has instructed departments to:
-
Remove the excess algae
-
Monitor nitrogen levels in the dam
-
Regulate private pisciculture activities
