  • Waste should be audited before coming to a collection.  It is important for homeowners to know how to identify and dispose of hazardous products.  Before coming to the collection, follow these simple instructions on how to conduct a Household Hazardous Products Audit (click here).       
  • Non-hazardous items are not accepted at the collections. It is common for residents to bring non-hazardous wastes, such as latex paint, water-based stains and finishes to the collections.  To dispose of these items, pour over cat litter to absorb liquid and throw away; or dry out and throw in the trash.
  • What to expect at a collection:  Upon entering the collection site, you will be greeted, given educational materials, and asked if you have mercury to recycle.
    1. You will be asked if you have mercury to recycle.
    2. Survey and Sort. While HHW staff members sort your waste, a six question survey will be given.  This is an anonymous survey used for administrative and statistical purposes only.
    3. Collection. After being surveyed and sorted, you will be directed to the unloading station where your waste is then collected by the contracted hazardous waste hauler. Residents are asked to stay in their vehicles throughout the entire process.
