The drinking water indicator combines information about 10 contaminants and 2 types of water quality violations that are sometimes found when drinking water samples are tested.
What is CalEnviroScreen?
- CalEnviroScreen is a mapping tool that helps identify California communities that are most affected by many sources of pollution, and where people are often especially vulnerable to pollution’s effects.
- CalEnviroScreen uses environmental, health, and socioeconomic information to produce scores for every census tract in the state.
- The scores are mapped so that different communities can be compared. An area with a high score is one that experiences a much higher pollution burden than areas with low scores.
- CalEnviroScreen ranks communities based on data that are available from state and federal government sources.

What are cumulative impacts?
- “Cumulative impacts” means exposures and public health or environmental effects from all sources of pollution in a geographic area.
- Cumulative impacts also take into account groups of people that are especially sensitive to pollution’s effects, such as young children and people with asthma, and socioeconomic factors, such as poverty, race and ethnicity, and education.
- For CalEPA’s definition of cumulative impacts, see the CalEnviroScreen 3.0 report.
What is Environmental Justice?
- State law defines environmental justice to mean “the fair treatment of people of all races, cultures, and incomes with respect to the development, adoption, implementation and enforcement of environmental laws, regulations, and policies.”
- Environmental justice principles are an important part of CalEPA’s goal to restore, protect and improve the environment, and to ensure the health of people, the environment and the economy.
- CalEPA asked OEHHA to develop CalEnviroScreen to identify communities suffering from cumulative impacts of multiple pollutants and people who are vulnerable to pollution’s effects.

Developed by the Office of Environmental Health Hazard Assessment (OEHHA) at the request of CalEPA, CalEnviroScreen is a science-based tool that identifies the California communities most burdened by pollution from multiple sources and most vulnerable to its effects. The tool will be used to help implement a state law (SB 535) that requires that 25 percent of the proceeds from the state’s cap-and-trade auctions be invested in projects that benefit disadvantaged communities, including 10 percent for projects located within these areas.
