The Dominguez Oilfield (Reyes Lease) is a 320 acre area approximately 10 miles south of downtown Los Angeles. Oil production ceased and remediation activities began in early 1999.  WorleyParsons Komex supervised the assessment and remediation of the 320-acre, 100-year-old former oilfield.  This land is the site of one of the largest brownfield redevelopments in Los Angeles County.

Soil impacted by petroleum hydrocarbons as a result of oil production operations was addressed using four specific types of remediation:   excavation of impacted soil and off-site disposal; excavation of impacted soil and on-site land treatment; excavation of impacted soil and on-site soil vapor extraction (SVE) utilizing constructed biopiles; and in-situ SVE. 

In addition to ex-situ remediation, the subsurface in-situ remediation of approximately 150,000 cubic yards of soil was simultaneously undertaken.  Professional staff from WorleyParsons Komex offices in the U.S., Canada, and UK were involved, as were geologists and engineers from several other consulting firms under WorleyParsons Komex direction.  A total of 670,000 cubic yards of hydrocarbon-impacted soil was remediated over a three-year period.
