  • Algaecides and Clarifiers: Follow label instructions; often, these can be taken to hazardous waste facilities if disposal is not permitted in regular waste streams.
  • Non-hazardous chemicals: Some pool chemicals, such as certain pH balancers, may be disposed of with regular trash if permitted by local regulations.

Using Hazardous Waste Collection Services

Many communities offer hazardous waste collection events or facilities specifically designed to handle chemicals safely. These services ensure that pool chemicals are disposed of according to environmental regulations and avoid contamination.

When using these services:

  • Transport chemicals in original containers with labels intact.
  • Keep chemicals upright and secure to prevent spills.
  • Do not mix different chemicals in one container.
  • Follow the instructions provided by the collection facility or event organizers.

Contact your local waste management authority or environmental protection agency to find the nearest hazardous waste disposal site or collection event.
