Rainwater Isn’t Always Clean: Study Finds Contaminants in Tanks
What Happened
Researchers from Adelaide University and Flinders University tested water from 100 household rainwater tanks and found bacteria linked to gastroenteritis and other infections in several tanks. The study detected Campylobacter in 13% of tanks, Salmonella in 10%, and Pseudomonas aeruginosa in 12%, including in some tanks used for drinking water.
Key Takeaways
The findings suggest rainwater can pick up bacteria and metals as it flows from roofs into storage tanks. Researchers stressed that the results do not mean drinking tank water will necessarily cause illness, but they highlight the importance of regular maintenance and monitoring of rainwater systems.
