The purpose of this report, Sound Health 2010, is to look back at environmental conditions in the Sound and its watershed over the last two years and compare them to conditions from the last 20 to 30 years (a separate report, Protection and Progress, details the management actions taken to improve the Sound). Sound Health 2010 uses environmental indicators developed from data collected by research and monitoring programsthat highlight trends in pollutant levels, land use and development, water quality, living resources, and sensitive habitat. From this snapshot, Sound Health 2010 addresses questions such as: Is the water cleaner; Are the fish safe to eat; Is the water safe to swim in; and Are fish still abundant.
