Systematic Enumeration of Algal Taxa in Relation to Water Quality of Murguma dam, Purulia District, West Bengal.

Dey, Pinaki; Sharan, Latika

Maintenance of freshwater resources and quality of their water is a big challenge inthe path of sustainable development. Based on the findings of more than five decades, it has been established that many algal taxa are regarded as bioindicators. They are pollution tolerant and an integral part of low-cost biological purification systems used for polluted water, especially those having organic pollutants. Keeping in view these attributes of algae, a study of Murguma reservoir and surrounding water bodies of Baghmundi block were carried out during 2020-2021 for algal taxa and physicochemical properties of water bodies. At present 17 parameters have been tested. These physicochemical and biological parameters have been studied from the surface water of selected five reservoirs for three years (2020-2022). One part of the Murguma reservoir shows oligotrophic water quality in physicochemical analysis and is also supported by the algal samples having genera like Cosmarium Corda, Spirogyra Link, Zygnema Agardh, and Oedogonium Link whereas algal samples collected from other sides are used by local communities for various day-to-day purposes including washing clothes, utensils, bathing, domesticated livestock washing etc. The algal flora of this zone of water included the members of Cyanophyceae, Chlorophyceae, and Bacillariophceae. Algal taxa such as Oscillatoria Voucher, Scenedesmus Meyen, Ankistrodesmus Corda, Phacus Dujardin, and Navicula Agardh, were recorded andare also included in Palmer's genus pollution index. Organic pollution and eutrophication of water are obvious and reflected by algal flora. Awareness regarding the deterioration of water quality at rural and urban levels is always required. Widespread use and popularization of cheap Algal tools in water quality monitoring and phytoremediation can be of great help.
