M Ayub, Jessore: The people of Jessore are drinking water that is dangerous for their health. Microorganisms have been identified in the water of hotels, restaurants and tea shops, which is a huge risk to the human body. Recently, a team of researchers from the Department of Environmental Science and Technology of Jessore University of Science and Technology (JUST) has found this microorganism.

The research team conducted a survey to determine the quality of drinking water supplied to various hotels, restaurants and tea shops in Jessore city. The researchers collected water samples from 35 places and verified the quality. The results of the study identified the presence of microorganisms in the supplied water samples.

The results of the study showed that the values ​​of water opacity (turbidity), electrical conductivity, pH, total dissolved solution, nitrate, sulphate, phosphate in the samples were within the limits approved by Bangladesh and the World Health Organization but the concentration of calcium and magnesium in several samples was poor. Was more than. In addition, the concentration of iron in 47 per cent of the samples exceeded the allowed limits of Bangladesh.

In addition, most of the specimens have been contaminated with fecal coliforms (various species of bacteria mixed with water or soil through the excrement of mammals or carcasses). People of Jessore city can be infected by germs by drinking such water. Among the samples collected, the water supplied to the roadside fast food and fuss shops was found to be highly biologically contaminated. As a result, water supplied to food shops and restaurants is harmful and a threat to public health.

Professor Saibur Rahman Mollah, head of the research team, said, ‘Most of the hotel, tea shop and restaurant owners in our country are not aware of health protection. To get rid of this problem, shop owners can regularly clean water containers with detergent, including the use of clean clean water containers with lids, and the use of long-handled water containers for pumping water in tea shops. In this case, the shop owners can ensure the health protection of the customer by using the water filters which are available in the market at low cost.

The other members of the research team were Assistant Professor Sadid Hossain of the department, FK Saima Tanzia, Assistant Professor of National Poet Kazi Nazrul Islam University and Shirina Akter, a postgraduate student of Javiprabi EST Department.
