A Review on pH, DO and BOD of the Sitalakhya River during Last Four Decades

Abstract

As a developing country, industrialization is rapidly growing up in Bangladesh. Most of the cases, the industrialization process don’t considering any impact on environmental body. In this study, the impact of unplanned industrialization on the surface water is the main focus. In between several resources, the water quality of the Sitalakhya River is our study area. Quality of the Sitalakhya River water is getting polluted day by day through industrial effluents and household wastewater, lube oil and oil spillage around the operation of river ports. The Sitalakhya river water quality analysis is considered between 1975 to 2018, qualitative and quantitative results for pH, DO and BOD were analyzed and also trends of these parameters were also analyzed. Day by day river water quality going far away from EQS value, which is significantly harmful to flora fauna. In this circumstance, industrial effluent and other environmental impacts from unplanned industrialization is main goal of this study. This study shows, how unplanned industrialization can damage an environmental system which is very harmful to our entire ecological cycle. If cannot control this unplanned industrialization, water body will damage and all related ecosystem will be effected.

Water Quality Plays an Important Role in the Socio-Economic Condition of the Local Community: A Study on the Kushiara River

“…According to Bangladesh Environmental Rules 1997, the water pH level should be 6.5 to 8.5 for fish production. The other important river water quality parameters are BOD, COD, DO, and TDS [5]. A study from Davis, et al, [6] asserted that freshwater fish require high-quality water to thrive.…”
