When the EPA came to El Paso in 2001 to test our region for Asarco contamination, UTEP researchers published the following research-paper:
They included several Tables, where they compared the values of chemicals-test-for in 1990 (pre-Asarco Contop-furnace haz-waste burning) vs 1997-2000. The sample sites were downwind of the Asarco smelter.J Air Waste Manag Assoc. 2001 Nov;51(11):1551-60. Analysis of temporal and spatial dichotomous PM air samples in the El Paso-Cd. Juarez air quality basin. by Li WW, Orquiz R, Garcia JH, Espino TT, Pingitore NE, Gardea-Torresdey J, Chow J, Watson JG.
The 1990 study showed no uranium was found in the samples --- but, seven (plus) years later, UTEP is finding uranium in all sample areas.
Would you send me the data (proof) from Asarco's stack samples (or industrial site) that these chemicals did not originate from the Smelter's illegal activities?
