The U.S. Environmental Protection Agency is offering a $2.5 million grant for researchers to investigate water contamination following fireworks shows. Fireworks contain perchlorate, and when the chemical does not completely combust it can leach into groundwater or enter streams.
It’s not a theoretical concern. Wells supplying Evart, Michigan, were tainted by perchlorate from years of fireworks shows that took place at a nearby fairgrounds. There are no national drinking water standards for perchlorate. But California and Massachusetts have their own regulations. One grant will be awarded and applications are due September 14, 2022.
