Maximum Residual Disinfectant Level Goal (MRDLG) - The level of a drinking water disinfectant below which there is no known or expected risk to health. About . MCLGs allow for a margin of safety and are non-enforceable public health goals. The Agency sets regulatory limits for the amounts of certain contaminants in water provided by public water systems. However, these are fairly expensive technologies and may be impractical for smaller systems. The goal of standard setting is to identify maximum contaminant levels (MCLs) which prevent adverse health effects. Meet criteria for avoiding filtration so that the following contaminants are controlled at the following levels: Turbidity: For systems that use conventional or direct filtration, at no time can turbidity (cloudiness of water) go higher than 1 Nephelometric Turbidity Unit (NTU), and samples for turbidity must be less than or equal to 0.3 NTUs in at least 95 percent of the samples in any month.
