' Sample Type =Primary (one sample is represented), =Average (duplicate samples are averaged). "Constituents reported in mg/I unless olhervnse noted.
A symbol "<•• before a number indicates that the value is not detedetl. The number following "<^ is the analytical limit of detection basetl upon the method and the sample matrix.
