Waterwise Wednesday: Persistent Perchlorate

Enjoy the Fourth of July fireworks. And please take time to carefully sweep firework launch and debris landing areas and properly dispose of the debris afterwards.

Perchlorate, a compound used as an oxidizing agent in fireworks (i.e., fuel to make the firework burn), persists in soil and water.

How persistent? Well, Mt. Rushmore National Memorial’s firework shows stopped in 2009. In a 2016 US Geological Survey high levels of perchlorate were still reported in the park – 38 micrograms in a groundwater sample and 54 micrograms/liter in a stream, both in excess of the EPA’s 15 micrograms per liter, and 274 times higher than samples taken outside the memorial park’s borders.

Please Pick Up Your Fireworks

The City of Kearney operates multiple street sweepers on a regular basis. They are not designed for picking up Fireworks debris that citizens leave on the street. This debris will not be picked up by the City. Please pick up after yourselves.

Waterwise Wednesday: Happy 4th of July!
