MCLG+ = Maximum Contaminant Level Goal established at the level at which no known or anticipated adverse effects on the health of persons occur and which allows
an adequate margin of safety; expressed in milligrams per liter unless otherwise specified.
MCL+ = Maximum Contaminant Level established as close to the MCLG as feasible taking into consideration costs and treatment
techniques applicable at public water systems; expressed in milligrams per liter unless otherwise specified.
