The sample was received on 1/8/2024 1:53 PM. Unless otherwise noted below, the sample arrived in good condition, and where
required, properly preserved and on ice. The temperature of the cooler at receipt was 2.90 C.
General Chemistry
Method SM 521013: The method blank result associated with batch 752-5859 was higher than the method -required limit of 0.2
mg/L.
Method SM 5210B: During the 5-day BOD/CBOD incubation period, the temperature inside the incubator exceeded the method -
required 20±1 °C control limit. On Tuesday, January 9, 2024, a weathered power outage occurred causing the incubator to read
25°C. The incubator was reset and the temperature returned to the method required limit. The following samples is impacted: Eff.-
726 Donlee Drive (752-15359-1), (LCS 752-5859/3), (SCB 752-5859/2), (USB 752-5859/1), (752-15355-A-1) and (752-15355-A-1
