Water body reasons for not achieving good status (RNAGS) identify the pressures that are impacting the status classification of water bodies. Reasons for deterioration (RFDs) identify the pressures that have caused the status of individual quality elements to deteriorate.
A level of certainty (suspected, probable or confirmed) is also assigned to each reason for not achieving good status.
