## Key Consensus Principles on Detection and Quantitation Levels

- Since quantitation levels are used as **regulatory compliance** levels in NPDES permits the following must be considered:

## Key Consensus Principles on Detection and Quantitation Levels

- Since quantitation levels are used as **regulatory compliance** levels in NPDES permits the following must be considered:
- No use for single results between DL & QL

## Key Consensus Principles on Detection and Quantitation Levels

- Since quantitation levels are used as **regulatory compliance** levels in NPDES permits the following must be considered:
- No use for single results between DL & QL
- Routine laboratory variability over time
