WFD Cycle 2 Lake ANC Classification

Alternative title(s)

Abstract

This dataset is a subset of "WFD Classification Status Cycle 2" and contains classification data for Acid Neutralizing Capacity (ANC) in lakes. Acid Neutralising Capacity (ANC) is one of the physicochemical quality elements along with Ammonia, pH, Total phosphorus and Dissolved Oxygen that make up the Physicochemical (Phy-chem) quality status of lakes water bodies. The Phys-chem status and the ecological status are used together to determine the overall status of a water body ANC is calculated using Alkalinity and Dissolved Oxygen and uses the pH value to apply the correct multiplication factor. No typology data or information is required and classification of status is purely based on the available chemical data. ANC classifications are High, Good or Moderate.

Quality and validity

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.
