" The ADEQ detected elevated levels of TENORM [technologically enhanced naturally occurring radioactive material] in the smelter flue dust at the Magma Copper Company's smelter and concentrator operations in San Manual Arizona. The exact source of the radiation is unclear, and it may originate from the ore concentrates, or the natural gas used in the smelter, or it may come from some other source."
"When the Arizona Department of Environmental Quality shared data with EPA on TENORM emanating from copper mines in mid 1992, the Agency began a study of the occurrence and distribution of TENORM at mines in the southwestern copper belt of Arizona. The following report is the result of that study. TENORM in SW Copper Belt of Arizona (PDF) (124 pp, 2,470 Kb) [EPA 402-R-99-002]"
"Soils and rock in copper mining areas may contain naturally-occurring radioactive materials (NORM):uranium, thorium, radium"

[the Ionics Brine concentrator (distillation unit) at Asarco El Paso was rated to handle LLRW (low level radioactive waste) - we are not told if that feature was needed at Asarco El Paso or not... Ionics has since been purchased by G.E. and the description of that unit is not available online]

Heather Mcmurray 's research uncovering poisoning of 1000 square miles around El Paso by Asarco smelter through what the EPA & US DOJ said was illegal burning of illegal hazardous/radioactive wastes 1991 to 1998. We have never been told what actinides, forever chemicals, dioxins etc are present from illegal Asarco actions(see 73 page 1998 conf. for settlement purposes only DOJ EPA Asarco doc,10/06 nytimes) see "Asarco secret document"
