🎆 Ever wonder what happens to all that smoke and debris after the 4th of July fireworks fade?
Each year, hundreds of millions of pounds of fireworks are launched in the U.S. While they put on a spectacular show, they also release perchlorate, a key fireworks ingredient and a known drinking water contaminant, into the environment.
Join Itasca Waters and Minnesota Sea Grant for our next Practical Water Wisdom webinar on June 4 to explore how fireworks affect our local lakes, rivers, and groundwater.
What we’ll cover:
💧How perchlorate impacts thyroid function and overall water safety.
💧Data from field studies and national water surveys before and after major holiday events.
💧How lake size, runoff, and direct deposition determine the actual risk to your drinking water.
Featured speaker: Andrew Jackson, Ph.D., Board-Certified Environmental Engineer and Chair of Civil, Environmental, and Construction Engineering at Texas Tech University.
🗓️ Thursday, June 4 at noon CT
