UK Upland Waters Monitoring Network

The United Kingdom Acid Waters Monitoring Network (UK AWMN), funded by a consortium originally led by the Department for Environment, Food and Rural Affairs, was established in 1988 to monitor the chemical and ecological impact of acid deposition in areas of the UK believed to be sensitive to acidification. Over thirty years on, its data-base provides an extremely valuable long-term record of water chemistry and biology which is unique for upland freshwater systems in the UK.

From 2013 the UK Acid Waters Monitoring Network became the Upland Waters Monitoring Network (UWMN) designed to track changes in surface water quality and freshwater biodiversity across all upland regions of the UK, not only those sensitive to acid deposition. As resources allow the role of the network will be expanded by adding new sites and new protocols needed to monitor the separate and combined impacts of all principal pressures facing upland waters, including acid deposition, nutrient-N deposition, climate change, toxic substance contamination and land-use change.

The annual data report for 2015-16 is downloadable from here. Some data for 2016-2017 are also available. Please see the summaries on the individual site pages.
