Monitoring of water quality at selected Shoalhaven locations is done each week during the summer season. The star rating categories are derived from the microbial assessment categories used in the National Health & Medical Research Council (2008) Guidelines.
Good rating - bacterial levels are safe for bathing according to National Health & Medical Research Council guidelines.
Fair rating - bacterial levels indicate an increased risk of illness to bathers, particularly those with lower immune function such as the elderly and young children.
Poor and Bad ratings - bacterial levels indicate a substantially increased risk of illness to bathers
