How to use the PDF

The .pdf contains multiple layers that can be selected individually to view the WFD classifications for different elements. Open the Layers menu bar on the left hand side of the document to view the different layers and use the eye icon to switch the layers on or off. Switching off the layer above will allow you to see the layer below, e.g. switch off the ‘Overall Water Body Class’ to view the ‘Ecological Water Body Class’, and so on.

Layers within the pdf

The table below listed the layers of information that can be found in the pdf and a brief description of this information Layer titles Description WFD Cycle 2 river water bodies The WFD divides the water environment into water bodies. These include lakes, reservoirs, streams, rivers, canals, groundwaters, transitional waters (estuaries) and coastal waters. This layer shows the river WFD water bodies within the Basingstoke and Deane area. Cycle 2 refers to the second cycle of the modelling of the extent and boundaries of the water bodies, which has been used since 2013. This layer file provides detail on the WFD river network. Physchem sampling sites 2015 This layer shows the location of sampling sites where data was collected between 2012 and 2014 and used to calculate the 2015 classification for Physico-chemical quality data. Physico- chemical samples include, Ammonia, Biochemical Oxygen Demand (BOD), Phosphorus, pH, Temperature and Dissolved Oxygen. We have provided information on Ammonia, BOD and P Inverts sampling sites 2015 This layer shows the location of sampling sites where data was collected between 2012 and 2014 and used to calculate the 2015 classification for invertebrates data

Summary of WFD Classifications

The WFD (Water Framework Directive) is a piece of EU legislation that requires member states to make plans to protect and improve the water environment. It was implemented into law in the UK in 2003. The Environment Agency is the lead competent authority for implementing the WFD in . The WFD applies to:  surface freshwater bodies, including lakes, streams, rivers and canals  transitional water bodies such as estuaries  groundwaters  coastal waters out to one mile from low tide  There are four main aims of the WFD, these are to:  improve and protect inland and coastal waters  drive wiser, sustainable use of water as a natural resource  create better habitats for wildlife that lives in and around water  create a better quality of life for everyone

The following information is taken from the UKTAG Recommendations on Surface Water Classification Schemes for the purposes of the Water Framework Directive (December 2007).

The classification process will result in each surface water body being assigned a status class. Surface water status is determined by the lower of a water body's 'ecological status' and its 'chemical status'. To achieve the overall aim of good surface water status, the Directive requires that surface waters be of at least good ecological status and good chemical status (Fig. 1). Good surface water status is one of the principal objectives for surface water bodies not designated as heavily modified or artificial. The other principal objective is to prevent deterioration of surface water status.

Figure 1 - Schematic representation of how results for different quality elements are combined to classify ecological status, chemical status and surface water status Key: "H" means high; "G" means good; "GH" means good or better and is normally treated as high for calculating, as relevant, ecological status and surface water status10; "M" means moderate; "P" means poor; "B" means bad; and "F" means failing to achieve good surface water chemical status.

Ecological status is indicated by the condition of a number of 'quality elements': biological; chemical and physiochemical; and hydromorphological. There are five classes for ecological status; 'high', 'good', 'moderate', 'poor' and 'bad'. The Directive requires that the overall ecological status of a water body be determined by the results for the biological or physicochemical quality element with the worst class (i.e. the quality element worst affected by human activity). This is called the “one out - all out‟ principle.

There are two classes for chemical status; 'good' and 'failing to achieve good'. The quality elements for assessing surface water chemical status are: priority substances; and other dangerous substances for which environmental quality standards have been established at European level.

The table below provides a narrative of what biological, chemical and hydrological conditions would be expected for each of status under WFD
