SALT LAKE COUNTY (News4Utah)- There are now a total of 35 places for people to drop off prescription drugs in Salt Lake County.

Officials say if you have some pills left in old prescription bottles don’t throw them away or send them down the drain.

“Those drugs then end up contaminating our groundwater and soil, causing serious environmental ramifications to our wildlife and water system,” Dorothy Adams, assistant executive director of Salt Lake County Health Dept. said.

Instead, Adams says visit one of the 35 drop box locations. Some of them area available 24 hours a day, seven days a week.

Saturday is National Drug Take Back Day. Many agencies will host “drug-take-back” events. For a list of locations click here.
