A yearlong study has concluded that fracking at a giant Los Angeles oil field won't harm the environment.
The study released Wednesday found no problems associated with the use of hydraulic fracturing for oil extraction at the Inglewood Oil Field in Baldwin Hills.
The 1,200-acre site is considered the largest urban oil field in the country.
Fracking injects pressurized water into rock to release trapped oil or gas. Residents living around the field oppose its use.
The study monitored wells before and after fracking.
Cardno Entrix, an environmental consulting firm, conducted the study, which was paid for by Plains Exploration and Production Co., the oil field's owner. The report was reviewed by two independent firms selected by the company and Los Angeles County.
