SWO04 was sampled twice on 8/27/2019 due to the first sample had high turbidity due to an old
n7etal absorbent sock degrading in the outfall outlet. This was identified after the initial san7ple was,
collected when the samples were being prepared for shipment to the lab. The metal absorbent sock
was removed. The second sample was collected which represented the normal outfall characteristics.
The averages of the results were included in the DMR.
