Column Name: TREATMENT_EFFICIENCY_EST


Description: The percentage of the toxic chemical removed from the waste stream through destruction, biological degradation, chemical conversion, or physical removal. This estimate represents the overall percentage of the toxic chemical destroyed or removed (based on amount or mass) throughout all waste management methods, not merely changes in volume or concentration and not merely the efficiency of one method in a sequence of activities. This also does not represent the waste treatment efficiency for the entire waste stream but only the removal or destruction of this specific toxic chemical in that waste stream. This does not include energy recovery or recycling activities. Energy recovery and recycling activities are reported in sections 7B and 7C, respectively. The value is calculated as follows: ((I - E)/1) * 100, where I equals the amount of toxic chemical in the influent waste stream, and E equals the amount of the toxic chemical in the effluent waste stream.
