Environmental Monitoring and

Remediation

in Shale energy Basins

Unconventional Oil and Gas Development

• Affects:

– Groundwater quality

• Organic molecules, chlorinated species, alcohols, metals

– Air quality

• Benzene, toluene, ethylbenzene, xylene (BTEX)

– Soil integrity

• BTEX and Poly-aromatic hydrocarbons (PAHs)

– Human health?

• Developing new methods

Unconventional Oil and Gas Development

Unconventional Oil and Gas Development

Eagle Ford Case Study BTEX Emissions

Highly localized to pad activities

Eagle Ford Case Study Soil Accumulation

White dots denote 0 BTEX detections, yellow dots denote 1 BTEX detection, orange dots denote 2 BTEX detections, red dots denote 3 BTEX detections, and blue dots denote that all 4 BTEX species were detected.

Future Directions

Develop new technology and best management practices for

instances of drilling-related contamination events

Remediation and recycling

Groundwater, surface water, soil

In situ detection of environmental abnormalities

Methane and VOC emissions

Dissolved gases in groundwater
