KESAB community monitoring number of samples with poor results.
•
The sampling locations include sites within the Council area, on the boundary, and the adjacent sites upstream and
downstream of the Council border.
•
KESAB Waterwatch has not monitored at two sites DRY550 and DRY560 along Dry Creek since 2005. They have also
removed two monitoring sites DRY 570 and DRY600 since 2005.
•
A higher incidence of poor samples were collected from Dry Creek when compared to sample sites of the Torrens River.
•
The Thomas Turner Reserve site has the highest number of poor samples (6) since 2006. However, number of poor samples
has reduced by half since the SoE 2007 recordings.
•
Very high levels of nitrate were recorded at several locations and indicate a diffuse source of nutrients entering the creek.
