This weekend the Marathon County Health Department is holding their third pharmaceutical take back event.

All you have to do is bring any prescription you no longer need to one of two locations in the county and they’ll properly dispose of the medications for you.

The hazardous materials coordinator says although it was once standard practice, recent studies have shown flushing old medications down the toilet can leave trace compounds from them in our groundwater.

"Some studies have also shown they've had really negative affects on aquatic life - fish and amphibians,” said John Schlicher, Marathon County’s hazardous materials coordinator. “It interfered with their development."

Pharmacists will be on hand to take your old medications from 10 a.m. to 2 p.m. Saturday at two locations.

One is at the hazardous materials collections site in Schofield and the other at the Municipal Building in Marathon City.
