For any small or rural wastewater systems, reporting can become burdensome. If you serve as an operator, sampler, and lab analyst, meeting expectations around data integrity and regulatory reporting can feel overwhelming. Limited staff, time, and resources often make it unrealistic to follow the same layered QA/QC processes used by larger utilities. However, there is a practical approach that works in these environments: working backwards from the final report.
Under the Clean Water Act, wastewater systems are required to monitor their discharges, and self-report results to regulators as part of their permit conditions. This process depends on the accuracy and completeness of the data generated in the field and the lab. Whether you are collecting samples, running tests, or entering results, your work directly supports a report that reflects compliance and carries legal responsibility.
Knowing that an accurate and complete report is the end goal, you can work backwards to decide how you can move forward. When you look at it this way, every task in the field and lab connects to a single outcome. At its core, every wastewater system shares the same goal: to submit data that is accurate and complete.
Remember, you may not be able to control all the things that happen to your system, but you can control how well you report it.
A lab analyst once shared that a major part of data integrity is self-reporting even when something is not going well.
They explained, “Several years ago we experienced a significant increase in inflow from stormwater, and the headworks could not keep up. We had to contact the state and notify them of the situation. If we had not reported it, we could have been fined.”
Many small systems would most likely agree that managing data integrity is cheaper than being fined for misreporting data or just not reporting certain incidents all together.
The most important step in a small system is a final pre-submission check. At this point you may ask yourself, Would I feel confident explaining this number if it were questioned?
Before results are reported, take a few minutes to confirm that all required parameters are present, values make sense, units align with permit requirements, and any quality control (QC) issues have been addressed or explained. This step serves as a critical safeguard, especially where there isn’t a second reviewer. Working backwards from this step can help small wastewater systems implement three key practices that will help you stay on top of your reporting.
- Real time data recording– Whether in the field or the lab, recording information immediately reduces errors and avoids the need to recreate data later. If a correction is needed, it should always be documented clearly to maintain transparency.
- Be consistent with basic QC– Even in small systems, required QC checks – like standards, blanks, or duplicates – should be treated as decision points. If something doesn’t look right, it needs to be addressed, not ignored. In many cases, QC is the only built-in check on the data.
- Clear sample identification and handling- Simple practices – like labeling samples with date, time, and location, and keeping track of holding times – ensure that results can always be traced back to their source.
This “working backwards” approach isn’t about adding more work. It’s about focusing limited time and attention on the steps that protect the data you ultimately report. By building your process around the final report, you strengthen data integrity at every stage because each step is clearly tied to producing accurate, traceable, and complete information.
It also reduces pressure around self-reporting. Instead of feeling like reporting is a high-stakes, last-minute task, the work leading up to it becomes more intentional and transparent. Every role in a small wastewater system contributes to that final number whether collecting the sample, running the test, or entering results. And when those steps are done with the end in mind, reporting becomes a natural outcome rather than a stressful checkpoint.
