Air National Guard Installation Restoration Program. Volume 1. Final SiteInvestigation Report, 181st Fighter Group, Indiana ANG, Hulman MAP, Terre Haute, Indiana

摘要

A Site Investigation (SI) was conducted as part of the Installation RestorationProgram (IRP) for the 181st Fighter Group of the Indiana Air National Guard, Hulman Field Municipal Airport (MAP), Terre Haute, IN. Six sites were investigated to obtain data to confirm the presence or absence of environmental contamination, to perform limited quantification of contamination if found, and to assess resulting human health and environmental risks. At five sites, although various contaminants (volatile organic compounds, polyaromatic hydrocarbon compounds, metals, and petroleum hydrocarbons) were detected, none were in sufficient concentration to cause adverse non-carcinogenic health effects and the cancer risk estimate is below the U.S. EPA target range. Hence no further action is recommended at those sites. At the sixth site nickel, chromium and lead were detected in concentrations which exceeded promulgated Federal and State standards for groundwater. Also this site is an area of high foot traffic. It is recommended that a specified grassy area be covered with concrete to help mitigate the potential for future transport of contaminants to subsurface soils and groundwater from surface runoff.
