Netherlands publishes atlas for pesticides in groundwater

0

The Netherlands has recently published a new Groundwater Atlas for Pesticides, which will be used by the Board for the Authorisation of Plant Protection Products and Biocides (Ctgb) to monitor groundwater quality.

The Groundwater Atlas was developed between 2015 and 2016 and commissioned by the ministries of Economic Affairs and Infrastructure and the Environment. Other organisations which have been involved more recently include Wageningen Environmental Research (Alterra) and the Dutch National Institute for Public Health and the Environment (RIVM), who have coordinated the data provided by the water companies. Alterra was responsible for monitoring the quality and consistency of all of the data in the atlas.

In the Netherlands, groundwater is sampled from thousands of sites and tested by the provinces and by water companies. This first version of the Groundwater Atlas uses a list of active ingredients and metabolites of plant protection products and biocides and uses the same system of product identification used for plant protection product approval in the Netherlands.
