NERC Environmental Information Data Centre 10.5285/9d923383-4e3c-4aa4-95f5-0e5cdbc5853e This dataset consists of results of chemical analyses of single water chemistry samples, taken from headwater streams during a survey in 2007. Water samples were analysed at the Centre for Ecology & Hydrology for chemical analysis of alkalinity (at pH 8.3), total oxidised nitrogen and soluble reactive phosphorus. Conductivity and pH were measured in the field using a regularly calibrated field meter. Data were collected under the Countryside Survey long term monitoring project managed by the Centre for Ecology & Hydrology. The Countryside Survey is a unique study or 'audit' of the natural resources of the UK's countryside. The sample sites are chosen from a stratified random sample, based on a 15 by 15 km grid of GB. Headwater stream surveys have been carried out in 1990, 1998 and 2007 with repeated visits to the majority of sites. The countryside is sampled and surveyed using rigorous scientific methods, allowing us to compare new results with those from previous surveys. In this way we can detect the gradual and subtle changes that occur in the UK's countryside over time. In addition to headwater stream data, soil data, habitat areas, vegetation species data and linear habitat data are also gathered by Countryside Survey.

Samples were taken from up to 591 1km squares sited across Britain, selected by random stratified sample. Samples were analysed according to standardized protocols at the Centre for Ecology & Hydrology, Lancaster in 2007/2008, or in the field. Data are managed by the Centre for Ecology & Hydrology.
