29. 2013 年美国政府问责局题为“需进一步分析查明针对国防部调整计划关岛公共基础设施的需求和成本”的报告称，由于自然灾害、维护不善和故意破坏，关岛的供水和污水处理系统有诸多不足之处。尽管过去 10 年关岛水务局在改善其供水和污水系统方面投资超过 1.58 亿美元，该水务局将继续根据关岛地区法院颁布的命令行事，即由于涉及遵守《安全饮用水法》和《清洁水法》的问题，要求进行多方面的处理和基础设施改善。目前关岛的饮用水系统不符合《安全饮用水法》。国防部监察主任称，由于现有资产状况不良，关岛的污水处理厂达不到初级处理标准，并且缺乏足够的能力。政府问责局在其报告中指出，在支持关岛目前的军事存在方面，水务局向安德森空军基地(包括西北侧)、关岛海军计算机和电信站以及 South Finegayan 海军住区提供了污水处理服务。不过，关岛立法机构代表和公共事业综合委员会主席称，水务局已接近满负荷运转，在基础设施没有明显改善的情况下，无法满足与调整相关的任何需求激增。
29. According to the 2013 report of the United States Government Accountability Office entitled “Further analysis needed to identify Guam's public infrastructure requirements and costs for the Department of Defense’s realignment plan”, the water and wastewater treatment systems of Guam have a number of deficiencies as a result of natural disasters, poor maintenance and vandalism. Although the Guam Waterworks Authority has invested more than $158 million in improvements to its water and wastewater systems over the past 10 years, it continues to operate under an order issued by the District Court of Guam requiring various treatment and infrastructure improvements because of issues relating to compliance with the Safe Drinking Water Act and the Clean Water Act. The potable water system of Guam is currently non-compliant with the Safe Drinking Water Act. According to the Inspector General of the Department of Defense, the wastewater plants in Guam do not meet primary treatment standards and lack sufficient capacity owing to the poor condition of existing assets. The Government Accountability Office noted in its report that, in terms of supporting the current military presence in Guam, the Authority provided wastewater services to the Andersen Air Force Base (including Northwest Field), the Naval Computer and Telecommunications Station Guam and the South Finegayan navy housing area. According to representatives of the legislature of Guam and the Chair of the Consolidated Commission on Utilities, however, the Authority is operating near capacity and is unable to meet any surge in demand relating to realignment without significant infrastructure improvements.
