S. 4384 would require the Department of Veterans Affairs (VA) to enter into an agreement with the Agency for Toxic Substances and Disease Registry, a component agency of the Department of Health and Human Services, to study whether exposures to toxic substances at Karshi-Khanabad (K2) Air Base in Uzbekistan are correlated with cancers and other diseases. Federal agencies would be required to provide to the agency any information needed to complete the study. The report would be due to the Congress within two years of enactment.
