  3. WFD Cycle 2 Lake total phosphorous classification

WFD Cycle 2 Lake total phosphorous classification

Summary

This dataset is a subset of "WFD Classification Status Cycle 2" and contains classification data for Total Phosphorus in lakes. Total Phosphorus is one of the physicochemical elements used, along with other physicochemical and biological quality elements, to determine the ecological status of a lake. The concentration and bioavailability of phosphorus influences freshwater ecology by driving the plant composition and biomass. Total phosphorus results are run through the calculator classification tool. The actual (observed) total phosphorus concentrations are compared with reference boundary phosphorus concentrations to derive a total phosphorus classification (High, Good, Moderate, Poor, Bad) for the water body for Water Framework Directive (WFD) purposes.

Lineage

The Water Framework Directive classification system is risk based and focuses on where there is likely to be a problem. It uses a principle known as "one out, all out", which means the poorest individual results drive the overall classification for a water body. It reports on over 30 quality elements, grouped into ecological status and chemical status. Ecological status includes physico-chem (e.g. nutrients, pH, dissolved oxygen, ammonia) , biological elements (e.g. phytoplankton, macroalgae, fish, invertebrates) , specific pollutants (e.g. metals and compounds, organic compounds) , hydromorphology (e.g. depth, width, flow, structure). Chemical status is assessed using priority substances, priority hazardous substances and other pollutants that present a significant risk to the water environment.
