Trucks vs. Pipeline• Truck Traffic• Road Damage Impoundments vs. Tanks

• Closed-Loop Drilling Systems• Recycling Logistics• Air Emissions

Tracking Wastewater• Characterize Wastewater• Record Volumes Produced• Verify Volumes Delivered

Water Reuse & Disposal

Water Recycling & Reuse• Volume and quality of wastewater• Chemical compatibility• Storage and transportation logistics

Water Treatment Facilities• Flowback & produced water

chemistry• Capacity & Capability limitations

(NORM, DBPs, heavy metals)• Central vs. drill site facilities

Water Disposal Wells• Geological & hydrological limitations• NIMBY concerns• Triggered seismicity considerations
