Long description: This papaer provides a trend analysis over a 12 year period (1988-2000) for 22 surface waters in acid-sensitive regions of the UK. Evidence of strong temporal variation has been identified, as has a widespread reduction in sulphate concentrations, hydrogen ions and inorganic aluminium species, the net result of which is an increase in acid neutralising capacity. The early period of the analysis was characterised by high concentrations of marine ions and stable pollutant sulphate concentrations. Later data showed lower concentrations of marine ions and declining sulphate, suggesting recovery from anthropogenic pollution only occurreed in the lattre half of the survey period, alhough the data must be observed in the wider context. Interannual variability is also high, supporting the case for long term analysis periods.
