- Match each result to its unit before comparing it with a limit.
- Flag bacteria, nitrate over 10 mg/L as nitrogen, arsenic over 10 ppb, and lead detections before aesthetic issues.
- Use trends over time, not one isolated test, for maintenance issues like hardness, pH, iron, and manganese.
- Save the lab report, treatment notes, and retest dates so future results are easier to interpret.
