Nitrates in groundwater

In 2012, Belgian groundwater contained 29.9 milligrams of nitrogen in the form of nitrates per litre of water. To achieve the sustainable development goal by 2030, this figure must be reduced. This objective will not be reached by continuing the trend since 2000. Nitrates in groundwater are therefore developing unfavourably.
