(e) All copper levels measured between the practical quantitation level and the method detection limit must be either reported as measured or they can be reported as one-half (1/2) the practical quantitation level (twenty-five thousandths (0.025) milligram per liter). All levels below the copper method detection limit must be reported as zero (0). 1 For analyzing lead and copper, the technique applicable to total metals must be used and samples cannot be filtered.
