Why do all water bodies have a chemical status of fail?
Investigations into classification status No data to show
Reasons for not achieving good (RNAG) and reasons for deterioration (RFD) All reasons (RFDs and RNAGs) attributed to the classification elements in
this water body.

Reasons for not achieving good status by business sector The issues preventing waters reaching good status and the sectors
identified as contributing to them. The numbers in the table are
individual counts of the reasons for not achieving good status with a
confidence status of 'confirmed' and 'probable', where the latest
classification is less than good status. There may be more than one
reason in a single water body. Note, table does not include reasons for
deterioration.
Significant water management issue Physical modifications Pollution from waste water Pollution from towns, cities and transport Changes to the natural flow and level of water Invasive non-native species Pollution from rural areas Pollution from abandoned mines Agriculture and rural land management 0 0 0 0 0 0 0 Industry 0 0 0 0 0 0 0 Mining and quarrying 0 0 0 0 0 0 0 Navigation 0 0 0 0 0 0 0 Urban and transport 0 0 0 0 0 0 0 Water Industry 0 0 0 0 0 0 0 Local & central government 0 0 0 0 0 0 0 Domestic general public 0 0 0 0 0 0 0 Recreation 0 0 0 0 0 0 0 Waste treatment and disposal 0 0 0 0 0 0 0 Other 0 0 0 0 0 0 0 No sector responsible 0 0 0 0 0 0 0 Sector under investigation 0 0 0 0 0 0 0 Total 0 0 0 0 0 0 0
