Federal Toxic Release Inventory (Tri): Waste Stream in Pounds

Time Range: 2008       Resolution: Census Block Group

This indicator is the total waste stream by census block group including air, water, and solid for facilities filing TRI reports. It is used to assess industrial density of a location and to assess the interactions between localized pollution levels and health outcomes.

The Toxics Release Inventory (TRI) is a component of the Emergency Planning and Community Right-to-Know Act (EPCRA). It is a database managed by the EPA that contains information on toxic chemical releases and waste management activities. The Toxics Release Inventory contains information on releases of nearly 650 chemicals and chemical categories from a wide range of industries. Information is reported annually.

The total waste stream reported on the federal Toxic Release Inventory is a direct measure of industrial density. Overall, the larger the value, the larger the facility. Used in conjunction with other TRI measures, it can be used to give a solid picture of the amount of industrial development in a location as well as the amount of pollution generated by local industries.

Rationale

Federal Toxic Release Inventory data can be used to both measure levels of locally generated air and water pollution and of the industrial density in a given location. Pollution levels, and industrial density as a proxy for pollution levels, though positively correlated with employment opportunities, are negatively correlated to health outcomes.
