CONTROL OF FOUL-SMELLING WATER: CAUSES, IMPACTS, AND COMPREHENSIVE REMEDIATION STRATEGIES

Unpleasant odors in water present significant challenges for maintaining quality,stemming from chemical compounds like hydrogen sulfide (HS),microbial activity,and organic decay.The Causes section identifies key sources, including sulfate-reducing bacteria, algal byproducts, and disinfection residues. The Health and Environmental Impacts section examines risks such as respiratory issues and ecological damage. The Materials and Methods section details the systematic review of literature from 2000 to 2025.The Results section provides data on odor prevalence and treatment effectiveness.The Discussion section evaluates solutionschemical oxidation, aeration, filtration, and preventive measures for their efficiency, cost, and sustainability, supported by practical case studies and emerging technologies. The Conclusion underscores the urgency of robust solutions amid climate-driven microbial growth. This review offers a detailed guide for water quality professionals to apply evidence-based strategies, ensuring safe and appealing water supplies.
