The High Dump/Slag Stockpiles program
was started in May 2003. The program consisted of the following:
||Number of samples
|Surface soil samples
|Existing monitor wells re-sampled
Some boreholes were well over 100 feet deep. In all, over 420 analyses
were performed on approximately 150 soil and water samples. Laboratory
testing indicates that, as in the other Study Areas, some metals
are present in the fill materials, and PAH are occasionally present
above the guideline values. The oil disposal area, a known area
of interest, was investigated as part of the Phase 2 ESA. The extent
of this area was defined and plans for its removal are being developed.
In addition to determining what environmental contamination may
be present, the study identified the various types of slag and other
fill materials that were placed to form the slag piles. The results
showed that the piles are almost entirely formed of slag, with other
materials such as mill scale, dust and general refuse (scrap metal,
etc.) deposited on top.
Phase 3 testing was completed in April 2004.
