Natural Gas Pipeline Spill Assessments

Lea County, NM

Subsurface investigations were performed at seventeen spill sites involving the release of natural gas liquids (NGL) from underground pipelines. Investigations were conducted using direct-push, hollowstem auger and rotary drilling techniques to collect soil samples to define the vertical and horizontal extent of impact. Soil samples were analyzed by field and laboratory methods, and proposed remediation ranged from noaction to blending impacted soil with clean soil to achieve recommended standards.
