Humphrey No 7: how the 2.5M lbs splits
2.5M lbs across all reported pathways
- Land Disposal 2.5M lbs 100.0%
Humphrey No 7's 2.5M lbs Form-R total is LAND - land disposal is 100.0% of the bar. Off-site transfers stay separate from air, water, and land releases. Leading chemical by pounds: Barium compounds (except for barium sulfate (CAS No. 7727-43-7)).
Carcinogen-classified pounds vs other reported pounds
Same cumulative TRI total as above, split by EPA/IARC carcinogen classification on each chemical: pounds share, not chemical count. Classification is not a site health-risk score.
