Where in France are there concerns about pesticides in drinking water

An investigation has revealed that tap water supplied to some 12 million people in France was sometimes contaminated with high levels of pesticides last year.

Data from regional health agencies, and collated by Le Monde, found that supplies to about 20 percent of the population, up from 5.9 percent the year previously, failed to consistently meet regional quality standards. 

The study highlighted regional differences in tap water quality. Hauts-de-France water was the most likely to be affected, with 65 percent of the population there drinking water contaminated by unacceptable pesticide levels. In Brittany, that level fell to 43 percent; 25.5 percent in the Grand-Est, and 25 percent in the Pays de la Loire.

Occitanie, in southwest France, meanwhile, showed the lowest level of non-compliance with standards, with just 5.1 percent of the region’s population affected by high pesticide levels in their tap water. However, figures show that 71 percent of people in one département in the region, Gers, were supplied with water containing high levels of pesticides.

Regional discrepancies in testing, including what chemicals are tested for, mean that results and standards are not uniform across France. Tap water in Haute-Corse is tested for 24 pesticide molecules; in Hauts-de-Seine, that figure rises to 477. 

One reason for regional testing standards are differences in local agricultural requirements.

Part of the increase in the year-on-year number of households supplied with affected water may also be explained by the fact that tests in many regions now seek to trace more molecules, Le Monde noted.

Water quality standards in France are strict – with a limit for pesticide residues set at 0.1 microgramme per litre, so the “high” levels found in tap water supplies may not represent a danger to health.

The question of the level of health risk to humans, therefore, remains unclear. The Agence nationale de sécurité sanitaire de l’alimentation, de l’environnement et du travail (Anses) has not defined a maximum safety level for 23 pesticides or their metabolites. Le Monde cites two metabolites of chloridazone, a herbicide used until 2020 on beet fields, for which only provisional safety levels in tap water have been set. 

Many of these molecules and their long-term effects remain unknown – and “the long-term health effects of exposure to low doses of pesticides are difficult to assess,” admits the Ministry of Health.

Michel Laforcade, former director general of the ARS Nouvelle-Aquitaine told Le Monde that health authorities have “failed” on this subject. 

“One day, we will have to give an account,” he said. “It may not be on the same scale as the contaminated blood affair, but it could become the next public health scandal.”

In December 2020, the Direction générale de la santé (DGS) recommended “restricting uses of water” as soon as the 0.1 micrograms per litre quality threshold is exceeded, in cases of residues for which there is no formal maximum health value.

But this principle is not always applied, according to France 2’s Complètement d’enquête programme.

In December 2021, the DGS asked the Haut conseil de la santé publique (HCSP) “for support on the management of health risks associated with the presence of pesticides and pesticide metabolites in water intended for human consumption.”

The HCSP, in response, said that “an active and urgent policy must be implemented to reduce the contamination of resources by pesticides”.

France declares epidemic as flu cases soar

The French health authority has declared a flu epidemic, while the country also faces a new wave of Covid cases and bronchitis is affecting young children.

France declares epidemic as flu cases soar

Santé publique France made the declaration of an epidemic on Wednesday, adding that three deaths have been recorded due to flu, while 20 patients are in intensive care.

With Covid-19 and bronchitis cases also currently high, health experts have urged people to get vaccinated – especially those over 65. “It is important for people at risk to be vaccinated against flu without delay,” insisted Santé publique France.

Cases have hit full epidemic levels in Brittany and Normandy, while the virus is in pre-epidemic phase in Auvergne-Rhône-Alpes, Grand Est, Provence-Alpes-Côte d’Azur, Centre-Val de Loire, Hauts-de-France and Île-de-France, with an increasing number of people heading to hospitals’ emergency departments with influenza-like illness. It is expected to cross over to epidemic levels in the coming days and weeks.

It has already hit French overseas territories including Martinique, Mayotte and Reunion.

Flu has hit epidemic levels much earlier than last season, when it did not peak until early Spring.
