What needs to be clarified
Check whether sampling time, concentration and flow records support a daily mass calculation.
Materials to prepare
- Analysis report with sampling time, parameter and units
- Daily flow log with recording intervals
- Sampling record and diagram with outlet operation and production cycles
What to compare
Align sampling with flow and operations; check units and formula. Establish whether the sample is grab or composite, how portions and flow were handled, uncovered intervals, and whether storage and compositing suit the parameter.
Possible outcome of the analysis
Provide a checked calculation for a supported interval, or explain why a daily estimate lacks support and specify requirements for resampling.
Limits of the conclusions
One concentration cannot describe the whole day. This review alone cannot establish substance source, environmental damage or regulatory noncompliance.
