Health Consultation—University of Texas at El Paso (UTEP), El Paso County Metal Survey

The Texas Department of Health, under Cooperative Agreement with the Agency for Toxic Substances and Disease Registry

Table of Contents | El Paso County Metal Survey—Health Consultations Summary page


CONCLUSIONS

  1. Although the average concentrations of lead and arsenic in soil from several locations on the UTEP campus exceed their respective soil based screening values for children, this is a college campus and these are areas that are not likely to be frequented by pre-school age children. Based on estimated exposures, it is not likely that other potentially exposed populations, including UTEP students, faculty, and staff, would experience adverse health effects associated with the contaminants found at any of the locations sampled. Potential exposures at the locations with the highest concentrations are further reduced by the presence of grass which decreases the likelihood of exposure to the soil. Based on available information we have concluded that the lead and arsenic found in the soil do not pose a public health hazard to any of the potentially exposed populations.

  2. The concentrations of lead and arsenic in soil from the daycare facility were well below their respective health based screening values for children. Thus, the contaminants in the soil from the daycare facility do not pose a public health hazard.

  3. Qualitatively we estimate the potential excess lifetime cancer risk associated with exposure to arsenic in soil from the UTEP campus to range from an insignificant increased risk to no apparent increased risk.

 


PUBLIC HEALTH ACTION PLAN

Actions Recommended

1. Appropriate environmental health education and risk communication should be provided to any interested parties.
