The regulation of nutrient neutrality in water bodies is a national requirement in the UK, which is governed by the Water Framework Directive (WFD) and the Environmental Permitting (England and Wales) Regulations. These regulations apply to all water bodies in the UK, including rivers, lakes, estuaries, and coastal waters.
Under the WFD, all water bodies in the UK must achieve "good ecological status" by 2027, which includes maintaining nutrient neutrality. The WFD sets out a framework for the assessment and management of water quality, and requires member states to develop river basin management plans that set out how they will achieve the objectives of the directive.
The Environmental Permitting (England and Wales) Regulations are the primary regulatory framework for water quality in England and Wales. These regulations require operators of certain types of activities, such as discharging wastewater into waterways, to obtain a permit that sets out conditions for the discharge. These conditions can include limits on the amount of nutrients that can be discharged into the water.
In addition to these national regulatory frameworks, the UK also has several other regulations in place to manage nutrient neutrality in water bodies. The Nitrate Pollution Prevention Regulations, for example, regulate the application of nitrogen-based fertilizers in vulnerable areas, such as those with high levels of nitrate in the water. These regulations aim to reduce the amount of nitrogen entering the water and help prevent eutrophication.
Similarly, the Phosphorus (Use in Agriculture) Regulations limit the use of phosphorus-based fertilizers in agriculture. This is because excess phosphorus can also contribute to eutrophication and harm aquatic ecosystems.
