“Asked about the difference in opinion between the federal and state agency regarding the sampling, Kunkle said, ‘I can’t answer why we have the disconnect,’ adding that the only sampling done at that monitoring location, called zonal sampling, ‘is really not intended to predict the long term environment or trends in the regional aquifer. That really should be done only with monthly monitoring.’”

A federal official says more testing is needed to determine whether a toxic chromium plume has seeped into San Ildefonso Pueblo’s groundwater, after the state called groundwater testing “conclusive evidence” the U.S. Department of Energy’s efforts at containment have been “inadequate.”
New Mexico’s Environment Department announced last month hexavalent chromium from Los Alamos National Laboratory had migrated to Pueblo de San Ildefonso land for the first time.
But Jessica Kunkle — the Los Alamos Field Office manager with the U.S. Department of Energy — told state lawmakers on the Radioactive and Hazardous Materials Committee on Monday afternoon the type of groundwater sampling conducted may not have told the whole story. The agency is working with partners to get a monitoring well installed “as quickly as possible,” she said, to get better data.
