PETITIONED HEALTH CONSULTATION

CHOULIC GRAVEL PIT
(a/k/a BABOQUIVARI DISTRICT)
TOHONO O'ODHAM NATION, PIMA COUNTY, ARIZONA


CONCLUSION

ATSDR classifies the Choulic Gravel Pit site as an Indeterminate Public Health Hazard.

The initial concern associated with cattle and wildlife drinking contaminated surface water has been addressed by the installation of a fence around the perimeter of the site. However, members of the Tohono O'odham Nation have recently raised concerns about the potential impact to groundwater or drinking water in the area. ATSDR has no groundwater contaminant data for this site and, therefore, can draw no conclusions about the public health impact associated with any groundwater or drinking water contamination.


RECOMMENDATION

The results of the upcoming investigation will provide additional information on contamination associated with the site. In particular, ATSDR should review environmental sampling results to evaluate the public health impacts from any groundwater or drinking water contamination associated with the site.
