Description
Sometimes, the monitoring network results provide an inhibited point of view to understand bacteriological process on the field. We must go further in contamination spatial or temporal structures to obtain a global picture. At Leucate, if a part of bacteriological contamination is correlated to precipitations, the main environmental factor to explain local variability seems to be the monthly variability population. This fact, completed by a spatial design, reveals a concentric gradient in the shellfish farrning area. Sorne hypothesis are discussed to explain this contamination (resurgence, aquatic birds droppings, ...)
