In 50 lakes in south-eastern Norway hydrogen-ion concentration (pH) and total hardness ("dH) were measured in surface water in the 1950's and then once again 10 years later. Significant acidificatio...
The chemistry of ground- and surface-water in areas of similar geologic settings are compared by plotting the equivalent concentrations of each component in an XY-diagram. The deviations of each che...
During the spring of 1985 shallow recharge area groundwaters at depths less than one metre in the Turkey Lakes watershed were observed to undergo short term (1 to 10 days) pH and alkalinity depressi...
Three upland Lake District Tarns, Scoat, Greendale and Burnmoor, have been evaluated using MAGIC (Model of Acidification of Groundwater In Catchments) to reconstruct past, present and future chemical ...
The Model of Acidification of Groundwater In Catchments (MAGIC) has been calibrated to 94 catchments in Wales, enabling the quantification of regional response to reduced emissions under the second s...
The 30-year record 1975–2004 of weekly samples of streamwater chemistry from Birkenes, Norway, shows 106 acid episodes below the threshold of ANC−50 µeq l−1. The frequency, severity ...
