The French-British company Perenco is the DRC's (Democratic Republic of Congo) sole oil producer and is one of the largest investors in the country. They arrived in the DRC in 2000 after CHEVRON sold their concessions. Perenco's onshore drilling program started in 2002 and offshore in 2004. The company has extensively invested in new wells, they have got between 250 to 800 wells. Perenco will normally continue operating in DRC until 2030.
In February 2009, concerned about the situation, two organisations (RRN and IPIS) mobilized experts to assess the impacts of the Perenco's activities on public health and environment in Muanda. The experts concluded there is a real problem of public health in Muanda. They have observed an increased incidence of cataract, glaucoma, trauma, conjunctival tumors, etc.
Another civil society organisations (CCFD-Terres Solidaires and ADEV) published a report focusing on the environmental injustices impacted by PERENCO in Muanda.
In December 2013, Senate recommended Perenco to clean up the region of Muanda and to invest more in social programs for communities in Muanda.
