Scientists discover tiny microbes with potential to cleanse waterways

Microbial communities in urban waterways have the potential to play an important role in cleansing waterways and also act as raw water quality indicators, a seven-year study suggests. The study found that canals designed to channel rainwater host microbial communities that could remove and neutralize organic pollutants in raw water. These organic pollutants are currently at trace levels in raw water -- well below the United States-Environmental Protection Agency (US-EPA) drinking water standards -- which is removed during water treatment processes.
