At Tracking California, we seek to provide the best available data to help our partners and stakeholders answer questions related to the environment and health. We collect and display data from health agencies, disease registries, environmental regulators and more.
Part of what makes our data unique is that many metrics are standardized with other Tracking state programs and across years, allowing for meaningful comparisons over space and time. In addition, Tracking works to shine a light on important data gaps that might be overlooked in regulatory processes. Tracking staff bring a variety of skills -- from programming to health education and community engagement to policy -- that helps us move data to public health action.
Some of data and tools unique to Tracking include:
- Agricultural Pesticide Mapping Tool -- This interactive display of agricultural pesticide use in California has data from 1991-2017 with maps, charts, and tables. Users can zoom in to specific regions, filter the data to show specific pesticides, and display the information in either English or Spanish.
- Water Boundary Tool -- This tool enabled users to modify and view drinking water system boundaries throughout California. With no other agency collecting this data, the tool provided mission critical information for a wide variety of stakeholders. After eight successful years of service, we are retiring the use of this tool as state agencies step in to carry the work forward.
- PFAS Maps -- We display the most current PFAS water quality testing from the California Waterboards on interactive maps.
- Hidden Lead Maps -- Our Hidden Lead investigation found that nationally, only 64% of children with elevated blood lead levels are ever tested. Data from this research are displayed in interactive maps, including the estimated number of children with elevated blood lead levels in each state, and the percent of children ever identified through testing.
