Land Disposal by Chemical in the 2015 TRI National Analysis
See Other Graphics in this Section
This pie chart shows which toxic chemicals were disposed of to land on-site in the greatest quantities in 2015.
The metal mining sector alone is responsible for 87% of the total quantities of zinc and lead disposed of to land in 2015. Land disposal quantities of these chemicals have not changed significantly in the past 10 years but large fluctuations have occurred from 2010 through 2015. Fluctuations occur in land disposal quantities reported by metal mines because even a small change in the chemical composition of the mineral deposit being mined can lead to big changes in the amount of toxic chemicals reported nationally.
