40. 如《关岛综合经济发展战略报告》所述，关岛环境保护局开展各种方案，定期监测环境状况。美国环境保护署的法规适用于关岛，但在某些方面，关岛本地法律比美国法律严格。关岛是一个幅员较小、人口密集的岛屿，因此其海洋环境是检验陆上人类活动对环境总体影响的一个重要标准。据查，所有指标均显示关岛海洋水质基本上优良。与建筑活动和天然侵蚀有关的土壤侵蚀是关岛南部特别令人关切的另一个问题，因为沉积物已导致河流入海口附近区域珊瑚礁被毁。
40. As stated in the report of the Guam Comprehensive Economic Development Strategy, the Guam Environmental Protection Agency implements various programmes that regularly monitor the status of the environment. United States Environmental Protection Agency regulations apply to Guam, but in some cases the Territory’s own laws are more stringent than those of the United States. Guam is a relatively small and high-density island; its marine environment therefore constitutes a key litmus test with regard to the overall environmental impact of human activity on the land. The quality of the marine waters has generally been found to be excellent across all indicators. Soil erosion, which is associated with construction activity or natural erosion, is another area of special concern in southern Guam, given that sedimentation has resulted in the destruction of coral reefs in areas adjacent to the mouths of rivers.
