Evaluation of the costs of the remediation system using peroxone for the treatment of chlorinated ethenes

The use of Advanced Oxidation Processes for remediation of contaminated areas has become an effective alternative to the destruction of contaminants when applied directly to soil and groundwater or through the treatment systems. This paper aimed to evaluate the cost of investment and operating a Pump & Treat remediation system to use peroxone as a treatment form for groundwater contaminated with chlorinated ethenes. The remediation system considered as hydrogeological characteristics of the study area and contaminants. The costs related to the equipment and materials necessary for the implementation of the system were considered as investment costs, while the operational costs considered electricity, hydrogen peroxide, labor, maintenance, administration, and laboratory analysis of groundwater. The results indicated that approximately 20% of the investment cost is associated with a treatment step and the operating cost step was R$ 551,484.86 (Year 1), R$ 606,913.32 (Year 2) and R$ 336,352.53 (Year 3), demonstrating an advantage over the traditional method of treatment with activated carbon.
