Land Disposal by Chemical & Industry

This pie chart shows the chemicals disposed of to land on site in the greatest quantities during 2022. The metal mining sector accounts for most of this disposal. To view the chemicals disposed of to land by sectors other than metal mining, toggle to the "Land Disposal, Excluding Metal Mining" chart.

Note: In this chart, metals are combined with their metal compounds, although metals and compounds of the same metal are listed separately on the TRI list (e.g., lead is listed separately from lead compounds).

The metal mining sector alone was responsible for 91% of the lead, zinc, and arsenic disposed of to land in 2022. These three chemicals made up 56% of the total quantities of TRI chemicals disposed of to land. Toggle to the "Land Disposal, Excluding Metal Mining" chart to see the chemicals released in the greatest quantities by other sectors, which shows a wider array of chemicals.

This pie chart shows the chemicals disposed of on site to land in the greatest quantities during 2022, excluding quantities from facilities in the metal mining sector.

Note: In this chart, metals are combined with their metal compounds, although metals and compounds of the same metal are listed separately on the TRI list (e.g., lead is listed separately from lead compounds).

• When the metal mining sector is excluded, a wider variety of chemicals make up the majority of land releases. For example, six different chemicals made up 56% of land releases when metal mining facilities are excluded, while three chemicals made up 56% of land releases when these facilities are included (as shown on the “Land Disposal, All Sectors” chart).
• Barium: Most land releases were from the electric utilities sector.
• Manganese: Most land releases were from the chemical manufacturing, primary metals, and electric utilities sectors.
• Zinc: Most land releases were from the primary metals sector.
