g that the fish kill was due to the chemical spill from SRWRC. While EPD and DNR tested water and other physical evidence across the water system from before the plant and to the end of the fish kill zone, Atlanta said it disagreed the investigators' conclusion that DWM operations caused the fish kill. State investigators said that water samples taken from the site were within normal range of iron concentration, but the sample collected at the site of Outfall No. 2, near where the fish kill was, did not get collected until five days after the spill. Atlanta officials said that the city water department continues to believe there is insufficient evidence establishing a definitive causal connection between the incident and the observed fish mortality. DWM said it had fully cooperated with the state in their investigation by providing operational records, environmental sampling data and technical expertise. There is no direct evidence demonstrating that any chemicals reached the South River, and water quality samples collected by DWM following the incident were within normal ranges for iron concentrations, according to the Atlanta water department.
