RIVM Report 703713003
This report gives an overview of the sampling results of several non-routine parameters: barium and strontium, trichloroaceticacid (TCA) and tribromoaceticacid (TBA) and the pesticides carbendazim, diuron, furalaxyl, ETU, mecoprop and 2,4-D. No bacteriological parameters were measured. Barium and strontium were demonstrable in both purified and unpurified water at all ground- and surface water-pumping stations. The concentrations of barium found were all below the maximum level for barium in drinking water. In the Netherlands there is no maximum level for strontium in drinking water. The measurements of TCA and TBA in purified and unpurified water at all surface water-pumping stations were all found to be below the demonstrable boundaries for the measurement method. Of all pesticides investigated, demonstrable sample concentrations were found in only two ground water observation filters located at a number of freatic ground water-pumping stations. In all other samples no trace was found of the pesticides under investigation. The results found will not present any problems for public health.
