Executive summary
- The paper measured human enteric and respiratory viruses by RT-qPCR and faecal indicators by culture in several environmental matrices.
- Sampling covered influent wastewater, reclaimed wastewater, biosolids, surface water and sediment across three campaigns.
- Reclaimed water reductions for E. coli and somatic coliphages remained below the log reductions discussed in EU reuse context.
- The paper reports weak correlation between classic faecal indicators and viral detections, supporting direct viral monitoring in sensitive settings.
What the paper covers
| Area | Paper focus | Why it matters |
|---|---|---|
| WWTP and reuse streams | Influent, reclaimed wastewater and biosolids were studied together. | Supports a system view of viral pollution rather than isolated sampling. |
| Environmental receptors | Surface water and sediment were included in protected Mediterranean areas. | Connects treatment performance with downstream ecosystem exposure. |
| Indicator interpretation | E. coli and somatic coliphages did not consistently predict viral detections. | Encourages careful indicator choice and direct viral evidence when needed. |
Relevance for water programs
- Map viral risk across treatment, reuse and environmental compartments.
- Document why reclaimed water programs may need more than bacterial indicators.
- Prepare matrix-specific sampling plans for wastewater, biosolids, surface water and sediment.
- Use AquaVerify Cloud to keep sampling site, campaign, matrix, target and review history connected.

FAQ
Does this page replace the original paper?
No. This page summarizes the technical relevance and links to the DOI or official source so teams can review the full methodology, data and limitations.
Is this a product approval claim?
No. The paper is presented as scientific context. Product selection, method verification and regulatory interpretation remain dependent on matrix, laboratory scope and competent authority requirements.
How should a laboratory use it?
Use it to prepare a technical discussion around targets, indicators, sampling design, controls, reporting and traceability before changing a routine workflow.
