There are 2 major groups of stakeholders described in the film, the Marine Corps and the people effected by diseased linked to the marine corps camps. The marine corps needed to grapple with the problems of waste disposal and the aftermath of how to deal with the effected people, while the people effected needed to survive the diseases, rebuild their lives, and persue justice from the military.
The main stakeholders portrayed in this film is the Marines and family members of Marines living at Camp Lejeune. Many of them have been diagnosed with cancer, likely caused by chemicals in the base's water supply. Several of the victims have united to question the government and the actions they failed to take after reports of polluted water.
The major stakeholders are those exposed to the contaminated water (and subsequently suffer from cancer and other major illnesses) and the Marine Corps. Unfortunately, the Marine Corps and other government agencies show fairly limited attempts to aid those fighting for information about Camp Lejeune. Moreover, several meetings within Washington DC reveal the nature of policy making; how special interest groups often overshadow the common welfare of the public. Jerry Ensingmer and his counterparts often deal with the harsh realities of fighting giants with slingshots, and often have to choose between family and trying to help those also effected by the contaminated water. There are many questions raised about how much governing bodies actually care about soldiers, and how deep the "semper fi" motto actually goes.
