Three surface soil samples (SS1-3) were mistakenly collected at AOC 44 instead of B-9 on March 14.  Analytical results are currently in question due to ITS Laboratory practices; however, when resampling is conducted, samples will be collected from B-9.

One soil boring (SB1) mistakenly drilled at AOC 44 instead of B-9, and samples collected on September 5.  These samples were only analyzed for copper based on results of preliminary comparison to background levels.  Analytical results are currently in question due to ITS Laboratory practices.  When resampling is conducted, samples will be collected from B-9.
