Shortage of drinking water is turning into a major problem in summer because of there are no deep tube wells in groundwater level in Khulna. People in Khulna city and five upazilas’ of the Khulna district face serious water crisis in this summer.
Officials of Department of Public Health Engineering (DPHE) claim that around at least 2.5 million people of Khulna city and Dighalia, Dumuria, Rupsha and Batiaghata upazilas’ became sufferer.
Officials of DPHE said to Bd Environment that groundwater level declined by 21 feet on an average in the five upazilas in economic year 2012-2013 while it declined by 26 feet in 2011. For this reason, people in numerous areas of these upazilas’ are need to depend on undrinkable pond water.
Contacted with some water experts, they said to BD Environment that “scanty rainfall, poor navigability and extreme use of underground water were the main reasons behind the fall.
The locality and government are
neglected to be responsible for the relentless degradation. As source of
livelihood, communication, and heart of people in Dhaka had been determined to
the Buriganga River but now it’s a major source of
running the capital. This happens due to pollution and building illegal
property by robbering.
Along with Buriganga, Turag, Shitalakkhya,
Balu and Bangshi is being a death trap
for increasing pollution and also indiscriminate sand lifting. The minimal
level of dissolved oxygen (DO) required for life to survive in these rivers do
Researchers of The Department of
Environment (DoE) had been an alarming message on levels of DO in these rivers
after three months research. They have analysis on various samples of chemical
whose were collected from these rivers
and the levels of DO in Buriganga, Turag and Bangshi were 0.38, 0.59 and
0.0 milligram per liter gradually.
According to the Environment
Protection Act (Amendment) 2010, the minimum required level DO is 5 mg/l for
any water body to sustain aquatic species including fishes and others is. The
minimal standard rate for water being eligible for treatment as drinking water
is 6 mg/l.
Contacted with Environment Erpert
Dr Ahsan Uddin Ahmed over phone, he said to Bd Environment that “such a DO
merge amount in water poses severe a great threats to biodiversity and
hydro-ecology”. “Random dumping of waste has put the rivers in and around the
city in a blackout”.
Professor Mujibur Rahman of Bangladesh
University of Engineering and Technology (Buet) said that government ought to
shift the tannery diligence from the Hazaribagh, Dhaka.
The chemical waste from the tanneries is a major polluter of these rivers.
It’s important that The DoE research had been found
that the level of DO at the Hazaribagh area of Buriganga River
was 1.06, 0.50 and 1.0 mg/l in January, February and March gradually. And the
Bio-Chemical Oxygen Demand (BOD) is also very high in these waters.
