EPA provides various resources to locate information on water pollution and how it has affected the animal populations living in these habitats:
EPA uses water quality and biological criteria to evaluate water quality and ecosystem health. The presence, condition and numbers of types of fish, insects, algae, plants, and other organisms provide important information about the health of aquatic ecosystems. The presence of toxics or other pollutants in water can affect aquatic life. Both types of criteria help scientists and regulators evaluate aquatic ecosystem health.

Wetlands are important features in the landscape that provide numerous beneficial services for people and for fish and wildlife. EPA has several resources that provide scientific and regulatory information about wetlands and wetland health:
- Wetlands Protection and Restoration
- Why are Wetlands Important?
- Benefits and Applications of Wetland Bioassessments
EPA also provides information about healthy watersheds and the pollutants that can affect them. Watershed conditions are important to the people, plants, and animals that live within the watershed.
