Locational Suitability of Paschim Boragaon Landfill Adjacent to Deepor Beel Wetland, Assam

Abstract

Deepor Beel, situated in the lower Assam region of Brahmaputra Valley, is a significant wetland that holds immense importance and is classified within the biogeographical region of the Burma monsoon forest. The beel acts as a crucial reservoir for storing water in Guwahati, aiding in mitigating the effects of flash flooding. The beel is endowed with luxuriant aquatic flora and fauna and maintains a well-balanced ecosystem. Nevertheless, the presence of the Paschim Boragaon Landfill in close proximity to the beel has raised concerns about the fragility of the biodiversity and ecosystem. The study was conducted to evaluate the appropriateness of placing a waste disposal site near a wetland and also how effectively did the Paschim Boragaon landfill adhere to the criteria specified in the Central Pollution Control Board (CPCB) and Central Public Health and Environment Engineering Organisation (CPHEEO). The landfill's establishment has disregarded the prescribed regulations imposed by the relevant governing body, posing a significant threat to the soil, water, and environment. This situation flagrantly violates the Wetland Rules of 2010, leading to detrimental effects on the diverse features and biodiversity of the beel. The landfill's close proximity has directly or indirectly disrupted the beel's heterogeneous characteristics. Hence, an urgent relocation of the entire landfill is imperative to protect the beel and uphold the internationally renowned Ramsar wetland's biodiversity.
