1 River Basin Characterisation 2 Risk Assessment outputs River Basin Management Team Environment Agency

2  Combined source assessments (ammonia, biochemical oxygen demand & phosphorus) via National SIMCAT models for rivers  Combined source assessment (total oxidised nitrogen) for rivers  Mines and mine waters for transitional and coastal waters (TraC) WHAT IS NEW ? New assessment or completely different method

3 WHAT HAS BEEN REVISED ?  Abstraction and flow regulation (rivers, lakes and transitional) Drafts have been shared with DEFRA/WAG, final version will be made publicly available, shortly  Acidification (rivers)  Mines and mine waters (rivers)  Pesticides (diffuse) in drinking water sources  Sediment (rivers)  Sheep dip (rivers)

4 WHERE TO FIND THE LATEST INFORMATION  http://www.environment- agency.gov.uk/subjects/waterquality/955573/10 01324/1654756/1903912/?version=1&lang=-e http://www.environment- agency.gov.uk/subjects/waterquality/955573/10 01324/1654756/1903912/?version=1&lang=-e  Method statements  Maps and supporting summary text

5 Supporting text including Summary of method changes Map of risk status for water bodies in England & Wales Table- numbers of water bodies against each Risk category

6 ABOUT THE RESULTS Risk is not the same as compliance/classification. Risk should be linked to an activity/activities & provide a forecast based on predicted changes to pressures (e.g. to 2015) Risk categories are the same as used for Article 5 reporting o 1a- At risk o 1b- Probably at risk o 2a- Probably not at risk o 2b- Not at risk o Not assessed/not able to assess

7 WHAT ARE THE ASSESSMENTS BEING USED FOR ?  Development of measures to help achieve WFD objectives  Future revisions to our risk-based monitoring programme
