Human Health Risk Assessment, Pope Air Force Base, North Carolina (AMC)
Abstract
A human health risk assessment (HHRA) of total trihalomethanes (TTHM) was completed for Pope Air Force Base (Pope AFB). The purpose of this assessment was to quantify risks to military personnel and their families living on Pope AFB ingesting base supplied water with elevated levels of TTHM. HQ AMC/SGPB supported the base bioenvironmental engineer's request for AFIERA to perform a HHRA. The HHRA reviewed all potential exposure pathways of drinking water by comparing sample results to the USEPA Region 3 established standards. When an analytical result was identified as being above the USEPA Region 3 risk based concentration (RBC), it was identified as a chemical(s) of potential concern (COPC). There are 4 chemicals that sum together for the TTHM value. Of the 4 chemicals, 3 were above the RBC at least 10% of the total sampling history (May 1985- May 2000). Each COPC was statistically reviewed and risk estimates were calculated. This health risk assessment evaluated both cancer and non-cancer end points. Calculated risk for both cancer and non-cancer indicated that expected exposures are within the EPA guidelines. The risk calculations indicate personnel should not incur adverse health impact due to the TTHM in drinking water.
