Title: Hexavalent Chromium; Contaminated Soil
Description: NIST scientists collected soil contaminated with hexavalent chromium, a potent carcinogen, from a site in Hudson County, N.J., to create a new Standard Reference Material (SRM). The SRM will help labs and government agencies determine the degree to which a site is contaminated and evaluate the effectiveness of cleanup efforts. The Statue of Liberty is in the background.
