Controlling mechanisms for stream water chemistry at the Pristine Ingabekken Site in mid-Norway: Some implications for acidification models

Stream water at the 18.7 ha pristine Ingabekken catchment, on granitic bedrock, in mid-Norway has been studied for 2 years, including intensive episode studies in the spring and autumn. The pH varied from over 7 at base flow to 5 or slightly below at high flow, while inorganic monomeric Al was
