NEW MEXICO (KRQE) — A toxic chromium plume from Los Alamos National Laboratory has spread onto Pueblo de San Ildefonso land, with contamination levels exceeding state groundwater standards. The New Mexico Environment Department says there is no imminent threat to drinking water on pueblo land or Los Alamos County because the plume is not near any known drinking well yet.

NMED says that the US Department of Energy’s chromium mitigation efforts failed, and because of that they are planning to file a lawsuit. Health officials say that long-term chromium ingestion can lead to cancer.
