The Environment Agency has released a new report and associated data detailing a national groundwater nitrogen inventory and heat maps for England. This initiative developed and applied a methodology to quantify the annual amount of nitrogen at risk of leaching into groundwater from diverse economic sectors. The findings are intended to bolster the agency's evidence-based regulatory approach.

This publication provides a detailed analysis and data tables that regulated entities, particularly those in agriculture and other sectors contributing to nitrogen runoff, should review. While this is presented as guidance and research, understanding the inventory and heat maps is crucial for demonstrating compliance with environmental regulations concerning water quality and nutrient management. No specific compliance deadline is mentioned, but the information supports the agency's regulatory framework.
