MCLG and MCL

A. Explain the practical difference between the MCLG and the MCL.
b. Draw the relationship of marginal social benefit and marginal social cost for the MCLG for lead, assuming it is set at an efficient level. Intuitively explain your model

NOTE: One of the key elements of a primary drinking water regulation is the maximum contamination level goal (MCLG). Defines the level of a pollutant at which no known or expected adverse health effects occur, allowing for an adequate margin of safety.

Once the MCLG is established the primary standard is set. The primary standard give the maximum contaminant level (MCL) allowed in drinking water. It is to be set as close to the MCLG as feasible. The MCL is the highest permissible level of a contaminant in water milligrams per liter (mg/L)

A. EXPLAIN THE PRACTICAL DIFFERENCE BETWEEN THE MCLG AND THE MCL.
The maximum level of a contaminant in drinking water at which no recognized or expected adverse effect on the heath of a person would occur is the maximum containment level goal. This is set by the EPA. Now maximum containment level goal is based on stringent considerations of public health it not practical for water systems to meet these stringent standards. When setting the maximum containment level goal, the effects of water on sensitive sections of the population are considered like infants, children, those with weak immune systems or the elderly. ...
