User friendly BLM
The new Guidance for deriving Environmental Quality Standards (EQS) under the European Water Framework Directive (WFD) supports the use of a tiered compliance assessment regime for metals that incorporates both correction for natural background concentrations and bioavailability. However, the guidance does not provide practical tools to implement a bioavailability-based compliance regime. Moreover, current BLM/WHAM normalisations for Cu, Ni and Zn are time-consuming and not sufficiently user-friendly for regulatory use. To this end, a quick, user-friendly and unified chronic BLM normalisation tool based on full Biotic Ligand Model (BLM) calculations have been developed for several metals (i.e. Cu, Ni and Zn). The tools require the input of the following abiotic water parameters: DOC, pH and Hardness concentration. These user-friendly tools, when used as part of a tiered approach, provide water managers with an opportunity to efficiently account for metal bioavailability in a transparent way and deliver a robust metric of potential environmental risk.
A website has been developed that will act as a portal for all aspects of metal bioavailability and its implementation and includes an online version of the user-friendly tools
The Biomet tool has been developed jointly by ARCHE and WCA. Sponsors of the tool are NIPERA, IZA and ECI
In order to use the tool you must register at our Biometdedicated website and obtain a Login account in order to access the tool and all supporting information.
