The studies in Gästrikland are aimed at examining water quality based on priority environmental goals. These are the nutritional content of the water "no eutrophication", oxygen status and the content of organic substances "living lakes and streams", acidity / acidification "just natural acidification" and metals "non poisonous/toxic environment".
The pages under "Sampling" provide a brief overview of chemical studies for 36 years, from 1969 to 2005. The report is based on the trend analyzes that are documented in "Gästriklands vatten, ændringer 1969 - 1999", Svelab Miljö-laboratorier AB, 1999-11- 23 and surveys 1969 - 2005.
