With the exceptions noted as flags, footnotes, or detailed in the section below; standard operating procedures were

followed in the analysis of the samples and no problems were encountered or anomalies observed.

Calculations are performed before rounding to minimize errors in calculated values.

All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise

detailed in the section below, or in the sample receipt documentation.

All laboratory quality control samples were within established control limits, with any exceptions noted below, or in the

associated QC summary forms.

Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. For diluted

samples, the reporting limits are adjusted for the dilution required.

With the exceptions noted as flags, footnotes, or detailed in the section below; standard operating procedures were

followed in the analysis of the samples and no problems were encountered or anomalies observed.

Calculations are performed before rounding to minimize errors in calculated values.

All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise

detailed in the section below, or in the sample receipt documentation.

All laboratory quality control samples were within established control limits, with any exceptions noted below, or in the

associated QC summary forms.

Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. For diluted

samples, the reporting limits are adjusted for the dilution required.

With the exceptions noted as flags, footnotes, or detailed in the section below; standard operating procedures were

followed in the analysis of the samples and no problems were encountered or anomalies observed.

Calculations are performed before rounding to minimize errors in calculated values.

All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise

detailed in the section below, or in the sample receipt documentation.

All laboratory quality control samples were within established control limits, with any exceptions noted below, or in the

associated QC summary forms.

Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. For diluted

samples, the reporting limits are adjusted for the dilution required.
