ER: Data Purpose: The ICR data were collected as part of a national research project to support development of national drinking water standards.
They should NOT be used to determine local water systems compliance with drinking water standards, nor should they be used to make personal judgements about individual health risks.
Units: Sample measurements are taken and are regulated in milligrams per Liter (mg/L). 1 mg/L= 1 part per million, or one contaminant p art per one million water parts. Data for chlorite is presented in ppm.
Results of Zero: A result of zero may indicate that a sample was analyzed, but that the result was less than the lowest value that the analytical method can reliably report.
