Dogs have been seen roaming for months and animal protection activists decided to make the complaint.
Investigations concluded that the dogs were swimming and drinking water in the Kasadi River, where several factories, including pharmaceutical, food and engineering, dump their chemical waste illegally. It can be dyes or detergent dye.
The danger of contamination is also affecting the fishermen in the area since the analyzes of the water carried out by the authorities have shown that it is not suitable for human consumption.
Animalists are demanding more research to see if reptiles, birds, and other mammals are also being affected.
The authorities assured that they are carrying out an investigation and that they will implement measures against those who are causing the contamination.
