Did a couple cursory google searches. Looks like the people funding this paper (SUEZ Spain) are selling a COVID senteniel service to track covid spread through the wastewater[0]. Nothing wrong with research funded by a for profit firm. However, in light of the, well, surprising claims this article makes, and how the article suggests that wastewater surveillance could have caught it that early and doesn't seem to be discussing the limitations of this approach (such as the apparent propensity for false positives...), it's something to keep in mind.
