Sustainable Water Management for Natural Gas Extraction From Marcellus Shale

摘要

1. Rapid development of unconventional gas industry in PA 2. Numerous (founded and unfounded) concerns 2.1 Environmental implications 2.2 Public health issues 3. Accidents happen (e.g., spills) 4. Gas migration is potentially a serious issue (especially in NE PA) that needs to be addressed 5. No evidence for groundwater contamination by the fracturing fluid 6. No irrefutable evidence for sustained impact on surface water quality in PA. 1. Marcellus shale development hinges on documenting environmental impacts and developing sustainable water management 2. Almost no direct disposal options for flowback water 3. Limited treatment options for disposal 4. Flowback water reuse appears to be the most effective option 4.1 Limited lifetime 4.2 Need to develop industries that will utilize cheap resources that can be recovered from shale gas wastewater.
