What is a Public Health Goal (PHG)?

California has also developed Public Health Goals (PHGs) for water contaminants that are used by the State in setting MCLs. PHGs are not regulated limits, they are goals developed by the California Office of Environmental Health Hazard Assessment (OEHHA). The PHG value is a theoretical estimate where no known or anticipated adverse effect on the health of persons would occur if a consumer was to drink two liters of water daily for 70 years. PHGs are unique to California and are comparable in concept to the EPA’s Maximum Containment Level Goals (MCLGs). 

It is important to note that PHGs do not consider whether the level is technologically or economically feasible or even measurable. The role of the PHG is to be utilized to ensure that MCLs are set "as close as possible" to the corresponding PHG with the primary emphasis on the protection of public health but also considering technological and economic feasibility.
