La turbidité quantifie le "trouble" de l'eau, lié à la présence de matières en suspension (argile, micro-organismes, débris).
Une eau trouble réduit l'efficacité de la désinfection (les germes peuvent se loger dans les particules). C'est un paramètre clé pour valider le bon fonctionnement de la filtration.
Pas dangereux en soi, mais associé à un risque microbiologique. Limite en sortie de traitement : 1 NFU.
