UK Acid Waters Monitoring Network
The United Kingdom Acid Waters Monitoring Network (UK AWMN), funded by a consortium 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 twenty-four 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 will become 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.
