Known issues with the databases Anomalous total phosphorus levels have been revealed for the period January 1991 – June 1996. The anomaly has been shown to be likely to result from an absolute error,

The laboratory are analysing the chemical composition of inland waters. We are since 1992 accredited by SWEDAC for the analyses of about 40 different parameters, as well as for sampling. In total,

Below are the accredited analytical methods and their measurement uncertainties listed, since November 2017. For information about earlier analytical methods from 1960s and onwards, see each method .

Known issues in the database Since January 2019 are the results reported as COD Mn i.e. in the unit mg O/l. Until December 2018 was only the amount of oxidant used (permanganattal) is given in our

The tungsten content in water is measured using the same method as other metals i.e. with ICP-MS, but our analysis is not accredited. For more information about the analysis method, see Metals in
