26 IMWA International Mine Water Association Path Forward Education and Training –Well educated operators –Aware of potential environmental impacts –Know how process operates –Are allowed to make own decisions

27 IMWA International Mine Water Association Path Forward Integrated Mine Water Management –Recycle –Reuse –Aquifer Storage and Recovery –Surface Storage –Expert Systems

28 IMWA International Mine Water Association Potential Future Technologies Selective Membrane Technologies Electrochemical Methods Selective Ion Exchange Freeze Crystallization

29 IMWA International Mine Water Association Conclusions – call it “Path Forward” if you want Mining CompaniesMining Companies –Give time for new technology AuthoritiesAuthorities –Allow for “non standard” solutions ResearchersResearchers –Identify what others “missed” Consultant CompaniesConsultant Companies –Provide better education for employees –Maintain good literature databases –Recommend intelligent technologies All of usAll of us –Try to become more open minded

30 IMWA International Mine Water Association Reinventing the wheel – again and again

31 IMWA International Mine Water Association Conclusions – Still the Path Forward Don’t repeat experiments others did beforeDon’t repeat experiments others did before Find gaps in current technologyFind gaps in current technology Think about technology outside your area and how it can be implementedThink about technology outside your area and how it can be implemented EducationEducation Courage and EnduranceCourage and Endurance Chain of custody for water samplesChain of custody for water samples In situ methodsIn situ methods PerseverancePerseverance
