Water pollution caused by leather industrial effluent discharges has become a troublesome phenomenon due
to its negative impact on environmental health and safety. In this paper, the wastewater in the vicinity
of Lawdar tannery areas was assessed in two years from October 2019 to June 2021 to determine physico-chemical
parameters of industrial effluents of Lawdar tannery at four different area points. Tannery effluents were collected
and all samples were analyzed in the laboratory and rated as no freshwater with parameters such as acidity and basicity,
temperature, electrical conductivity, total dissolved solids, total suspended solids, chemical oxygen demand, biological
oxygen demand, color, turbidity, hardness, alkalinity, and several positive and negative ions. The investigation showed
that all physico-chemical parameters were higher than the standard disposal limits of discharged water quality.
The findings of this research will assist the government and tanneries in the treatment of wastewater before
discharging to the environment and monitoring the dump sites with regards to disposal arrangement of the tannery
effluents and environmental assessment.
