Description
The leather industry plays a significant role in economic development; however, the discharge of untreated or inadequately treated tannery effluent poses serious environmental challenges due to its high concentrations of dissolved salts, organic pollutants, and potentially toxic heavy metals. The present study focuses on the assessment of the physico-chemical characteristics and Water Quality Index (WQI) of tannery effluent in Dindigul District, Tamil Nadu, India.
This study evaluates important water quality parameters, including pH, turbidity, electrical conductivity, total dissolved solids, alkalinity, hardness, chloride, sulphate, and selected heavy metals. The analytical results are assessed with reference to relevant water quality standards to determine the extent of pollution and the potential environmental risks associated with tannery effluent discharge. The Water Quality Index provides an integrated approach to understanding the overall quality of the effluent and identifying the major parameters contributing to water pollution.
The findings highlight the importance of effective effluent treatment, regular environmental monitoring, and sustainable wastewater management practices to minimise the adverse impacts of tannery waste on aquatic ecosystems, soil quality, and groundwater resources. This study provides valuable insights for researchers, environmental scientists, students, and policymakers working in the fields of environmental science, industrial pollution control, and water resource management. It also emphasises the need for appropriate treatment strategies to protect water resources and promote sustainable industrial development in tannery-intensive regions.
