Te Importance of a Systematic Approach
A contribility study is not a one- size-fits- all contricise.

Each shortlisted technologiy is now evaluated across four key dimensions: technical, economic, environmental, and social. This multi- criteria accessach ensures balanced decision- making.
Technical Feasibility
Assesses whether thee technology can effectively affecte cleveup goals under site-specic conditions. Dotazy to answer include: Can thee technologiy tread all contaminations of concern? Are there site consitints (e.g., shallow badck, high clay content) that limit experceance? What is thee prediceted mement time? How reliable is te technology based on prior applications?

Ekonomické Feasibility
Develop detailed cost estimates for each technologiy, including capital costs, operation and accordance (O 'Imp; amp; M), monitoring, and eventual closure. Use net present value (NPV) analysis to compe long-term costs. Consider cost drivers such as energiy consumption, reagent supply, waste disposal, and labor. duration, including post- santion monitoring.
Environmental and Social Impacts
