Vewin list of plant protection products and biocides in surface water updated
On a yearly basis, Vewin communicates to Ctgb the list of active substances and metabolites of plant protection products and biocides that are detected at one or more occasions above the drinking water limit at drinking water abstraction points, including the relevant monitoring data.
Beginning in January 2021 Ctgb will use the monitoring data over 2015-2019 for the assessment of the drinking water criterion (national assessment for fate and behaviour in the environment) for the production of drinking water from surface water. The updated list can be consulted at www.vewin.nl/stoffen. Prior to the submission of an application for product authorization, applicants can request the raw data needed to calculate the 90th-percentiles for individual abstraction points from Vewin.
