A 2010 survey on nitrates in Bessin water

This survey signed V. T. examined the nitrate content of the water distributed in the Bessin. It recalled regular checks and presented the threshold of fifty milligrams per liter as the then applicable regulatory limit, in reference to the decree of 20 December 2001. The article associated its overrun with consumption restrictions, especially for infants and pregnant women.

According to the latest samples cited, no municipality in Bessin exceeded this limit. However, some were close to it: 47.5 mg/l for part of Bayeux Intercom Ouest — Barbeville, Bayeux, Cussy, Saint-Vigor-le-Grand, Subles, Vaucelles and Vaux-sur-Aure —; 47.3 mg/l for the SAEP of the source of Thaon — Amblie, Thaon, Cambes-en-Plaine, Fontaine-Henry, Le Fresne-Camilly and Lantheuil —; and 46.1 mg/l for Bayeux Intercom Est — Monceaux-en-Bessin, Saint-Martin-des-Entrées, Saint-Vigor-le-Grand and Sommervieu.

Conversely, the drinking water syndicate of Omaha Beach displayed 2.5 mg/l. It served Asnières-en-Bessin, Cricqueville-en-Bessin, Deux-Jumeaux, Écrammeville, Englesqueville-la-Percée, Formigny, Longueville, Louvières, Saint-Pierre-du-Mont and Vierville-sur-Mer. Its president Jean-Marie Oxéant explained this result by two resources located under ten meters of clay, in an area of relatively protected traditional crops. He stated that requests for resource sharing were mainly demine with the quantity available. The union had helped Port-en-Bessin during a cut and regularly fed La Cambe, while maintaining room for manoeuvre.

Another part of Bayeux Intercom Ouest, including Commes, Longues-sur-Mer, Magny-en-Bessin, Arromanches, Manvieux and Tracy-sur-Mer, received water at 3.5 mg/l. For Les Oubeaux, La Folie, Monfréville, Neuilly-la-Forêt, Saint-Marcouf-du-Rochy, Saint-Martin-de-Blagny and Vouilly, the samples cited gave 28.8 mg/l to the capture of Colombières, 36.8 mg/l in southern Bernesq and 31.3 mg/l in northern Bernesq. The majority of the municipalities of Bessin were, according to the survey, between twenty-five and forty milligrams per liter.

A box explained that nitrates were among the frequent pollutants of rural groundwater, especially in connection with fertilizers and septic systems. He mentioned their role in infant methemoglobinemia, described as a defect in oxygen transport, and presented them as a possible indication of other pollution, bacterial or pesticide-related.
