Household Hazardous Waste

Disposing of toxic materials in your trash, down the drain, or on the ground can seriously impact our environment and public health. Household hazardous wastes can contaminate septic tanks, wastewater treatment systems, ground water, and even our drinking water if not disposed of properly. Household hazardous wastes are leftover household products that are toxic, ignitable, corrosive, or reactive, such as – cleaners, paint, pesticides, adhesives, polishes, and fuels.

Lead Tackle Accepted This Year
This year, the Loon Preservation Committee will be onsite at Concord's Household Hazardous Waste Collection Day to collect old lead tackle. Lead tackle poisoning is the number one cause of documented adult loon mortality in New Hampshire. Lead sinkers and lead-headed jigs weighing one ounce or less are now illegal to sell or use in freshwater in the state. Lead tackle can be identified as soft and easily dented, and will leave a gray mark if rubbed on paper. Tackle purchased in 2010 or earlier is likely to contain lead. Anglers should check their tackleboxes and bring lead tackle to this event for proper disposal.

Unacceptable Items to Bring:

Latex Paint (Dry Out, Dispose In Trash)Fluorescent Light Bulbs
Fire ExtinguishersSmoke Detectors
Radioactive WasteBiological Waste
ExplosivesAmmunition

Help minimize hazardous waste by only buying what you would use. Seek alternative methods and products to reduce use of hazardous waste materials. Always read the product labels for information about proper disposal and special directions for storage. Excess materials should be carefully stored in a cool and dry location out of reach from children and animals. Product labels that read, “danger,” “poison,” “warning,” “flammable,” “reactive,” “corrosive,” “toxic,” or “caution” indicate that an item is a hazardous waste product. All household hazardous materials need to be carefully disposed of for public safety and to protect our environment.
