Hypothesis
Are airborne spores a significant source of microfungi in treated municipal water systems?
Conclusion
Airborne spores are an important source of microfungi in water storage reservoirs, and microfungi can grow on the inner surfaces of water pipes and in sediments.
Supporting Evidence
- Microfungal spores were recovered from all air samples collected.
- Filamentous microfungi were found growing on the inner surfaces of water pipes.
- Microfungal growth was more prolific in sediments than on pipe walls.
Takeaway
This study found that tiny fungi can come from the air and grow in water pipes, which can be a problem for drinking water.
Methodology
Air samples were collected from reservoirs, and biofilm and sediment samples were analyzed for microfungal growth using microscopy and culture methods.
Potential Biases
Sampling methods may disturb biofilm and lead to fragmentation of fungal colonies.
Limitations
The sample size for pipe sections was small, and the uneven distribution of microfungi may affect results.
Participant Demographics
The study focused on the water supply system serving approximately 70,000 residents in Rockhampton, Australia.
