Something else to note: The lab tested for chromium in two ways: one test (ICP) measures all chromium of any kind, and the other measures hexavalent chromium specifically. The ICP test returned a concentration that was an order of magnitude smaller than the hexavalent test (0.0003 vs 0.0104 mg/L). That is to say, the tests contradict each other (because the whole is smaller than the part). https://www.documentcloud.org/documents/28055380-j2673-1-uds-level-2-report-final-report/ https://www.documentcloud.org/documents/28055380-j2673-1-uds...
