Natural Resources Damage Assessment
Natural Resources Damage Assessment

This event affected an ~84-acre area, directly resulting in the deaths of an estimated 6,800 fish. Other aquatic resources were impacted by the sudden change in pH which occurred as a result of this acidic wastewater entering the lake. The reduction in ecosystem function may have a wide reaching effect on the entire aquatic system.

The pollution leads to yield of poor quality of fish with the smell of chemicals. In general, pH of the effluent is found to above 11, which become lethal to all species of fish. Again, the textile industries dispose large quantities of sulphates in their wastewater; this can be converted in the environment to hydrogen sulfide, a very poisonous gas.
