Issued April 3, 1997
UPTON, NY -- The U.S. Department of Energy's (DOE) Brookhaven National Laboratory (BNL) today released further data that support previous findings about the location and extent of the tritium plume in groundwater on its site, south of its High Flux Beam Reactor (HFBR).
Both the U.S. Environmental Protection Agency and the Suffolk County Department of Health Services continue to state that the contamination poses no public health threat.
The chart below summarizes results to date from the 63 wells that were installed from one-fifth of a mile south of the HFBR and southward. Peak concentrations in some groups of wells have increased compared to previous announcements, because data from additional wells have been included. Additional data from the remaining wells is expected next week.
