The Savannah River National Laboratory (SRNL) was tasked with preparing and shipping samples for Hg speciation by Eurofins Frontier Global Sciences, Inc. in Seattle, WA on behalf of the Savannah River Remediation (SRR) Mercury Task Team. The eighth shipment of samples was designated to include two Tank 43 (2H Evaporator System Feed Tank) samples: a surface sample (HTF-43-15-52) and a variable depth sample taken at 161” (HTF-43-15-54). The third sample submitted was from the 2H Evaporator Overhead Tank (OHT) #2. All samples were received by SRNL on May 11, 2015. The OHT-2 was not placed in the SRNL Shielded Cells but was instead placed in a refrigerator in 773-A, B-wing upon receipt and kept at 4°C. The Tank 43 samples were left in their stainless steel dip bottles until they were opened and an aliquot of each diluted 1:10 with Eurofins deionized water on June 3, 2015. Following initial dilution in the Shielded Cells, the diluted Tank 43 samples were immediately moved to refrigeration and kept in the dark until prepared for shipment to Eurofins.
