- Review of environmental standards (16 specific pollutants, groundwater threshold values for risk, invasive non-native species, river flows (mid and high), water levels in lakes, intermittent discharges and acidification in rivers)
- Review of phosphorus standards in rivers
- Review of biological standards (including methods for macrophytes, phytobenthos, benthic invertebrates, fish, phytoplankton, macroalgae and angiosperms)
- River flows for good ecological potential (published 04/12/2013)
These documents can be found under the 'Resources - Environmental Standards' section, and for the River Flows for GEP, the 'Resources - Assessing the status of the water environment' section.
