Question

write short note on water pollution in Andhra Pradesh ​

Answer 1

Answer:

Explanation:

Environmental pollution is taking a toll on the quality of Krishna River water, if the survey conducted by the biological science experts of Acharya Nagarjuna University (ANU) is any indication.

The experts have expressed concern over the rapid deterioration in the water quality and its impact on the fauna.

ANU scientists reviewed the data related to the samples collected from the river over a decade and shared the same with The Hindu on the eve of the World Environment Day which is celebrated on June 5 every year.

Krishna River is the lifeline for many towns and thousands of villages as it caters to the domestic, industrial and irrigation needs of several districts through which it flows.

However, the scientists said that the water was getting polluted, affecting the fauna and the food chain of the river eco-system.

The survey findings assume significance in the wake of the National Green Tribunal (NGT) giving a rap on the knuckles of the the State government for dumping sewage directly into the river and allowing indiscriminate sand mining on its banks.

Pollution doubles

The ANU scientists, in its review of data, have found a steep increase in Biological Oxygen Demand (BOD), an important quality parameter, at the points where the river crosses towns and rise in alkalinity (pH) at points where the river crossed the villages.

High BOD and alkalinity, as it signifies increased levels of pollution, have an adverse impact on the food chain.

“The water quality of Krishna River has deteriorated with the polluting parameters doubling in the last decade. The pollution levels have increased phenomenally days after when the river is the focus of activity such as pushkarams and auspicious days when thousands take holy dip in it,” suggest the findings.
