Much of the oil sought by Occidental Petroleum is under Indian land. In the Peruvian Amazon, OXY "polluted principal water sources used by several groups of Indians in the Peruvian Amazon. It did so for close to 30 years, at a time when the region lacked the protection of environmental laws. People in the region say they're still living with this legacy. The second half of the story takes place in Ecuador [where] ... the company uses more modern technology and is notably cleaner. But as the indigenous movement has strengthened and sometimes hampered oil drilling, Occidental has used coercive methods to gain approval for exploration."
