With the dramatic increase in wildfires, fire retardants are being used more and more as a firefighting tool. But as their use increases, the harmful side effects of these chemicals are coming under increasing scrutiny.

The chemicals, largely consist of ammonia compounds, are known toxins to fish and other aquatic life. Studies have shown retardants can kill fish, alter soil chemistry, feed harmful algae blooms and even encourage the spread of invasive plants. Yet there is little regulation of their use and no safer alternatives on the market.
