Abstract:
Lakes are one of, if not the most important part of an ecosystem. Lakes are generally formed as a consequence of the tectonic or glacial activity in a typical region. Many people still use lake water as a source for drinking water and bathing. This study focuses on the water quality of the lakes in birulia. This study is important as it will provide the current water quality of these lakes and to see if the water of these lakes is still edible. The purpose of this inquiry was to evaluate the Birulia Lakes' water quality. Twelve water samples were collected from DSC Lake, Eastern Lake, Model Town Lake, and Boroitola Lake, which are all separate lakes. Three different sampling points are present at each sampling site. Odor, temperature, pH, total suspended particles, turbidity, iron, dissolved oxygen (DO), oil and grease, and biological oxygen demand (BOD) were the samples' physicochemical characteristics. To determine the overall water quality state of the study region, all the evaluated features were compared to national and international water quality criteria. Water has been shown to have a pH range of 6.5 to 8.5. Data that came within this range were obtained from our research at the three points of DSC Lake and Eastern Lake, as well as at the two points of Model Town Lake and Boroitola Lake. However, the results for Model Town Lake and Boroitola Lake are not within this range. Here, we can see that the water's pH values are rather close to the national norm. Additionally, several of the BOD readings from all points of our tests were within the acceptable range. BOD5 concentrations were higher than expected in a couple distinct samples. The water quality is also satisfied by the following parameters: EC, Turbidity, Iron, Temperature, DO, TSS, Oil & Grease, and Odor. In short, this study will help us determine the water quality of the lakes by comparing the parameters we get from the lake water to the standard parameter provided by the DPHE (Department of Public Heath Engineering).
