Differences between grand totals in VANDRG1, VANDIND, VANDRG4 and VANDUD, respectively, for years 2010-2018, are due to updates of input data, which are not yet implemented in VANDIND and VANDUD. Data on discharge of nitrogen, phosphorus and organic matter is incomplete for the year 2016. Therefore only data on discharge of wastewater, will be disseminated for 2016.
