The Ventura County-based oil producer facing financial liabilities relating to accusations it contaminated Bakersfield’s municipal water system in June filed Wednesday for Chapter 11 bankruptcy protection that would allow the company to reorganize its debts while continuing to do business. Griffin Resources LLC’s bankruptcy paperwork states it owes between $100,001 and $1 million to a total of up to 99 creditors. … A lawsuit the city of Bakersfield filed July 24 alleged Griffin “intentionally, recklessly and negligently” polluted local drinking water by allowing pressurized natural gas to backflow into municipal pipes starting June 3.
