EPA Awards Nearly $2.5M For Research To Assess Perchlorate After Firework Events

Today, the U.S. Environmental Protection Agency (EPA) announced $2,499,579 in research grant funding to Texas Tech University for research on the behavior of perchlorate after fireworks events near water sources.

“Protecting our water resources and ensuring clean drinking water is one of EPA’s top priorities,” said Chris Frey, Assistant Administrator of EPA’s Office of Research and Development. “With this research grant, Texas Tech University will be able to provide states and utilities with further knowledge on how to protect drinking water from perchlorate contamination.”

Perchlorate is a chemical used in rocket propellants, explosives, flares and fireworks. Recent increases in the use of fireworks have caused concern over potential increases of perchlorate in ambient waters that serve as sources of drinking water. Perchlorate in drinking water sources can be a health concern because above certain exposure levels, perchlorate can interfere with the normal functioning of the thyroid gland. Prior research has investigated water contamination from fireworks; however, there are gaps in understanding the magnitude and extent of perchlorate contamination before, during, and after fireworks are discharged around drinking water sources.

The awarded researchers at Texas Tech University will evaluate the relative impacts of perchlorate from fireworks on six drinking water sources across the U.S. including a groundwater source. Observations from the sites will be integrated into the Soil and Water Assessment Tool (SWAT), a public domain model, to expand its ability to assess the impact of firework-driven perchlorate emissions. Project results will provide states and utilities with data on the behavior of perchlorate after fireworks events which could be used to determine whether any actions are needed to reduce exposure via drinking water.
