LAFAYETTE, Ind. (WLFI ) - A reminder for those still setting off fireworks - be sure to pick up the debris so it doesn't run off into storm water.
Because of the recent rain, city officials are warning people to pick up after they light fireworks. If not, the debris could run off into the Wabash River and local creeks.
Lafayette Renew Asst. Superintendent Angela Andrews said fireworks contain phosphorus chemicals and nitrogen and when added to water it can take out oxygen. She said this is extremely dangerous for aquatic life.
There are also harmful metals and salts that give the explosions their colors.
News 18 asked Andrews if the debris is harmful for people. Andrews said some of the debris is filtered out, but not all of it. So there is a possibility of it ending up in someone's drinking water.
"There are storm sewers that go directly to the river so we need the public to police that and filter that for us," said Andrews.
Again, people have until July 9 to set off fireworks. Those hours are from 5 pm until two hours after sunset.
