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

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.
