Establishment of Chromium Workgroup -
In March 2004, scientists from the Division of Science, Research and Technology (DSRT) were charged with reviewing the current human health-based soil clean-up criteria for chromium. This was done in response to concerns voiced by the Hudson County community where most of the chrome ore processing residue waste sites are located. An internal DEP workgroup was formed and chaired by Eileen Murphy, Ph.D. (DSRT). A report was prepared in 2005 with the findings of the workgroup (see link below). This chromium webpage was created as a mechanism to keep community members and other stakeholders informed on departmental chromium reports, projects and issues. It is updated routinely by the Office of Science (formerly DSRT).
