In April 2015, AmazonWatch released videos reportedly sent from a whistleblower inside Chevron. The videos purportedly show employees and consultants finding petroleum contamination at sites in the Ecuadorean Amazon that the company claimed was cleaned up years earlier. These videos were confirmed as legitimate by Chevron legal counsel. According to the company, the videos show routine testing to establish the perimeter of oil pits. The company further stated that it is not possible to determine from the videos whether the sites shown are the responsibility of Chevron or its former partner, Petroecuador. According to Amazon Watch, the videos contain a map confirming that the sites are Chevron's, and contain footage of interviews with villagers known to live in the area for which Chevron is responsible.
