Study shows no major oil contamination found in Oxnard Plain water
A new study shows petroleum-related and other gases present in groundwater overlying an oil field on the Oxnard Plain, as well as unanswered questions about gases in five water wells, but no widespread contamination of the water supply. State and county officials said they are reviewing the 66-page report by scientists from the U.S. Geological Survey before determining what, if any, future actions should be taken. The study confirmed what scientists suspected two years ago after finding petroleum-related gases in water wells but adds new details.
