# Objectives

"

• 

# Improve the design and planning of water infrastructure in shale oil and gas operations to reduce the impacts to local communities and environment.

• 

# Model temporal and spatial variations in water quantity and quality for a hypothetical oil and gas field with intense development.

• 

# Provide an analysis of the impacts 1) demand on water resources 2) truck traffic 3) water reuse potential

• 

# Provide optimized water infrastructure recommendations based on specific impacts.
