Maximum containment level goal

Safe Drinking Water Act. (1974, 1986, 1996). Specifically applied to water supplied for humans consumption, this act requires the EPA to set maximum levels for contaminants in water delivered to users of public water systems. Two criteria are established for a particular contaminant the maximum containment level goal (MCGL) and the maximum contaminant level (MCL). The former, the MCLG, is the level at which no... 

Nitrites Maximum Contaminant Level (MCL) and Maximum Contaminant Level Goal (MCLG) limits have been determined as 1 mg/L each by the Environmental Protection Agency (EPA). Infants below the age of six who drink water containing nitrite in excess of the MCL could become seriously ill and, if untreated, may die. Symptoms include shortness of breath and blue baby syndrome. 

The first step in using the AHP to analyze a decision problem is to hierarchically break down the decision problem (objective) into its constituent components and identify the alternatives to be evaluated. The resulting hierarchy consists of the overall objective (goal) and one or more levels of sub-objectives. The alternatives to be evaluated are added at the lowest level of the hierarchy. According to Saaty (1980, pp. 79-83) a cluster should not contain more than 7 elements because results from psychological tests show that 1+1-2 are the maximum number of elements a person can effectively compare simultaneously.
