In a transfer to safeguard water assets and guarantee clear consuming water, the EPA has awarded an almost $2.5 million analysis grant to Texas Tech College to assist examine the conduct of perchlorate, a chemical generally present in rocket propellants, explosives, flares, and fireworks, after fireworks occasions close to water sources. This analysis is predicted to offer helpful insights to states and utilities on the best way to shield consuming water from perchlorate contamination.

Enhancing Water Useful resource Safety

The EPA has lengthy acknowledged the significance of preserving water assets and sustaining the integrity of consuming water sources. With this grant, Texas Tech will spearhead analysis efforts to deal with issues associated to the elevated use of fireworks and the potential rise in perchlorate ranges in ambient waters used as sources of consuming water.

Perchlorate contamination can pose well being dangers as it might disrupt the conventional functioning of the thyroid gland when publicity surpasses sure ranges.

Filling Information Gaps

Whereas earlier analysis has shed some gentle on water contamination ensuing from fireworks, important gaps persist in understanding the magnitude and extent of perchlorate contamination earlier than, throughout, and after fireworks are discharged in proximity to water sources. By assessing the relative impacts of perchlorate from fireworks on six water sources throughout the US, together with a groundwater supply, the researchers at Texas Tech goal to bridge these information gaps.

Built-in Strategy

The challenge will undertake an built-in strategy, combining area observations, laboratory research, and superior modeling methods to comprehensively consider the conduct of perchlorate following fireworks occasions.

Texas Tech’s researchers will measure perchlorate ranges at chosen websites throughout July 4th occasions, in addition to periodic firework shows at baseball stadiums situated close to two rivers. By conducting measurements earlier than and after main fireworks occasions and through subsequent rain occasions, the staff will assess perchlorate inputs attributable to runoff, infiltration, and direct deposition into water our bodies.

Increasing Modeling Capabilities

To reinforce the attain and affect of the examine, the analysis staff will combine all chemical, bodily, and organic observations from the six examine websites into the soil and water evaluation software (SWAT). By increasing the capabilities of SWAT, a publicly out there mannequin, the researchers goal to enhance its capacity to evaluate the affect of perchlorate emissions ensuing from fireworks.

This integration will present helpful insights into the conduct of perchlorate after fireworks occasions, empowering states and utilities to make knowledgeable selections relating to the necessity for mitigating publicity by water sources.

Nationwide Collaboration

As a part of this groundbreaking analysis, Texas Tech College will collaborate with present sampling networks, together with the Clear Air Standing and Traits Community (CASTNET) and the Nationwide Atmospheric Deposition Program (NADP). By leveraging these networks and conducting nationwide surveys of public water provide intakes earlier than and after intervals of fireworks, the challenge goals to seize a complete image of perchlorate contamination throughout the US.


The EPA’s grant to Texas Tech for perchlorate contamination analysis marks a major step towards safeguarding water assets and defending public well being. By conducting a radical analysis of the conduct of perchlorate after fireworks occasions close to water sources, this examine will equip states and utilities with important knowledge vital for figuring out applicable actions to reduce publicity by consuming water. By means of collaboration, superior modeling, and intensive area research, Texas Tech is poised to contribute helpful insights that can help environmental stewardship and the preservation of unpolluted water provides throughout the nation.
