Perchlorates dans les eaux destinées à la consommation humaine. Bilan d’une campagne nationale d’occurrence en France

Abstract : Perchlorate in drinking water is a new concern for public and sanitary authority due to the recent detection in drinking water and its effects on the thyroid function. Health Ministry entrusted a national survey of perchlorate in drinking water to French Agency for Food, Environmental and Occupational Health & Safety (Anses) to have data on exposure by drinking water. In association with Regional Agencies of Health and the Ministry of Health, the Nancy laboratory for Hydrology of organized on all the metropolitan and overseas departments a sampling representing with 25 % of the consumer population. Furthermore, a campaign of analyses on vulnerable sites was organized in association with FP2E in 34 departments of metropolitan France. Perchlorate was measured with a limit of quantification of 0.5 µg.L−1 thanks to an analysis by two dimensions ion chromatography coupled with a mass spectrometer The results highlight for the national campaign: – For the resources: contents lower than 4 µg.L−1 in 94 % of the cases and lower than 15 µg.L−1 in 99 % of the cases ; – For treated waters: contents lower than 4 µg.L−1 in 97 % of the cases and lower than 15 µg.L−1 in 100 % of the cases. Samples taken in vulnerable zone in association with the Professional Federation of the Companies of the Water highlighted slightly superior concentration levels but systematically lower than 15 µg.L−1. The contamination of drinking water by perchlorate is very localized and concern mainly the regions of the North, Picardy on sites coinciding with zones of historic bombardment.
