"...for three smelter studies: El Paso, Texas Lead Study [19], Helena Valley Lead Study [20],
and Silver Valley-Revisited Lead Study [17]. In the Midvale Community Lead Study [22] ....
The isopleths [i.e. graphs], which show increasing soil-lead concentrations in the vicinity of the smelters,
“support the conclusion that the smelters are the primary sources of lead contamination in the
area.” In addition, the Heavy Metal Exposure Study [60] found that “there was a general trend
toward increasing levels of environmental metal burdens with proximity to the smelter.” The
evidence for the emitter being the contributing source of the lead, therefore, stems from
increasing soil-lead concentrations with decreasing distance from the emitter."

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"
