CalEnviroScreen

CalEnviroScreen is a screening methodology that can be used to help identify California communities that are disproportionately burdened by multiple sources of pollution. CalEnviroScreen 4.0 is the latest iteration of the California Communities Environmental Health Screening Tool. The original and subsequent versions were developed by the Office of Environmental Health Hazard Assessment, or OEHHA, an office within the California Environmental Protection Agency. This version of CalEnviroScreen incorporates the recent publicly available data for all indicators. It also improves in the way some indicators are calculated to better reflect environmental conditions or a population’s vulnerability to environmental pollutants. One new indicator — Children’s Lead Risk from Housing — has been added to help capture another exposure that affects health and contributes to the pollution burden communities face. The new CalEnviroScreen version 4.0 analyzes the latest data from 21 indicators of environmental, public health and socioeconomic conditions in California’s 8,000 census tracts. These indicators range from air and drinking water contaminants to pesticide use, toxic releases, cleanup sites, low birth weight infants, poverty and unemployment.
