Household Hazardous Waste Day 4-20

Household Hazardous Waste

The Somerset County Hazardous Waste Collection Program gives residents and farmers a legal and cost-free way to dispose of unwanted household items that cannot be disposed of in the regular trash.  This drop-off opportunity is for residents only. 

Proof of Somerset County residency is required; (current driver's license, valid lease, tax bill or any other bill with a Somerset County address). Pre-registration is not required.  No businesses / commercial vehicles allowed at these events.

Occupants should remain in their vehicles until otherwise instructed and store hazardous materials in trunks, cargo areas or truck beds.

Five events are held annually at various locations around the county from 9 a.m. to 2 p.m. to enable residents to take advantage of the program.  Following is the 2024 schedule:

March 16 Bernards Township Public Works Garage   277 South Maple Ave Basking Ridge 07920
April 20 Warren Township Public Works Garage   1 Bardy Road Warren 07059
