The Pacific Islands large aquatic ecosystem comprises the U.S. territories of Guam, the Commonwealth of the Northern Mariana Islands (CNMI), and American Samoa. Guam and CNMI, both of the Mariana Islands, are located within Micronesia Region of the Western Pacific Ocean. American Samoa is located in the Polynesia Region of the South Pacific. The watershed of the Pacific Islands large aquatic ecosystem covers an area of 470 square miles. The economy of the three territories is driven by tourism, the U.S. military, and fishing.

There were 15 TRI facilities reporting for 2011 in the Pacific Islands: nine in Guam, one in American Samoa, and five in the Northern Mariana Islands. Electric utilities reported the largest TRI air releases, accounting for 77% of the total for 2011. Air releases fell by 50% from 2003 to 2011 and by 32% from 2010 to 2011.

Almost all of the surface water discharges for 2011 were nitrate compounds reported by one federal facility's wastewater treatment plant. Surface water discharges increased by 75% from 2010 to 2011 and more than doubled from 2003 to 2011. Another federal facility reported on-site land disposal of lead, accounting for almost all land disposal or other releases in this region for 2011. While land disposal or other releases varies from year to year, it did decrease by 35% from 2010 to 2011.

The ecology of these territories is monitored by the Region 9 EPA, as well as local EPA and DEQ offices in the territories. To learn more about ongoing efforts to protect the Pacific Islands, visit: www.epa.gov/region09/islands.
