Versions Notes

One of the aims of The European Water Framework Directive (WFD) is that the Member States monitor and assess the ecological and chemical status of all surface water bodies (rivers, lakes, transitional and coastal waters) and to ensure that they achieve a good status by 2027, with an interim deadline of 2021. The question is, what is meant by a good status and how to assess it? A good status of a water body can depend on several factors such as its physical, chemical, and biological characteristics, which can mean a lot of data. The water quality index (WQI) is a tool to provide a numerical value that indicates the overall health of the water in a particular area. A summary of how the WQI has developed and how it can be used was provided. When managing joint water bodies, it is especially important that decisions are made on a uniform basis, and the status of the water body is assessed in a similar way. During the project NarvaWatMan, the comparison was made of how the status of the river Narva is assessed both in Estonia and Russia. Based on the collected data, a joint water quality index was developed, and the received results were presented [1].

Funding

This research was funded by the Project ER25 NarvaWatMan (Water Management of the Narva River: harmonization and sustention) under the European Neighbourhood Instrument and co-financed by the Estonian EU external border programme for 2014–2020 (https://estoniarussia.eu/ accessed on 21 November 2023), under TalTech project number V19016 and supported by the partners.
