Two workers sort through old paint cans during hazardous household waste collection event

Are old medicine bottles, paint cans, and cleaning products taking up space in your cabinets?

We’ve got the solution! The San Antonio River Authority (River Authority), in collaboration with local partners, holds six Household Hazardous Waste (HHW) Collection Events each year downstream in Wilson, Karnes, and Goliad counties. According to the Texas Commission on Environmental Quality, household hazardous waste is defined as products containing chemicals that can pose safety risks if not managed correctly. The River Authority is encouraging county residents to visit and drop off unwanted household hazardous waste, electronics, tires, and unused pharmaceuticals. These collection events are essential to the community because they 1) offer residents a safe and convenient way to dispose of unused HHW and 2) help protect local creeks and the San Antonio River from harmful pollutants.

Many folks still believe that the proper way to dispose of expired and unused medications is to flush them down the toilet—but you knew better! With your help at our Spring and Fall Events in 2023, the River Authority and our partners collected approximately over 900 pounds of pharmaceuticals alone! Thanks to you, these products will stay out of wastewater treatment plants and our local creeks and rivers. Let’s beat that record in 2024!
