Total Suspended Particulate in Southern Arizona

  • Sampling with the Hi-Q High Volume Portable Air Sampler

  • Sampling Rate: 12 - 15 cfm

  • Uses 4 inch borosilicate glass fiber filters

  • Samples ran for 24 consecutive hours

Clean and Dirty Filters


Analysis
Analysis in Southern Arizona

All samples are analyzed for heavy metals and water soluble Ion content.

  • Ion Chromatography

  • Samples are analyzed for water soluble ions.

  • Prominent ions detected: Calcium, Potassium,

  • Magnesium, Sodium, Ammonium, Chloride, Acetate,

  • Formate, Nitrate, Sulfate

  • Inductively Coupled Plasma Mass Spectroscopy

  • Resolves metals and metaloidsconcentrations within the

  • samples.

Conclusions and future work
Conclusions and Future Work in Southern Arizona

  • High levels of airborne contaminates present at the site clearly indicate health risks to local populations and surrounding ecology.

  • Further sampling at site and investigation into contaminations sources is currently underway.

  • As part of the EPA Superfund fund program, information gathered at the site will be of significant importance in determining cleanup procedures and preventative measures implemented at the site.
