How we check

A listing appears on HazmatDrop only once we have confirmed it on an official source, and every page says where its facts came from and when we last checked them.

Where the list starts

Each state’s list starts from the state environmental agency’s published list of local household hazardous waste programs, then each program is checked against its own page.

• California: CalRecycle’s household hazardous waste guidance, the Department of Toxic Substances Control (DTSC) statewide map of household hazardous waste facilities as a starting point, and each county, city or regional agency’s own page. 180 California programs are listed.
• Florida: the Florida Department of Environmental Protection (FDEP) county household hazardous waste contact list (Oct 8, 2026), county websites, and the WasteMap Florida index as a starting point. 79 Florida sites and events are listed.
• New Jersey: NJDEP’s solid and hazardous waste guidance as background, then each county utilities authority, improvement authority or county government’s own household hazardous waste page and flyer. 14 New Jersey programs are listed.
• New York: NYSDEC’s household hazardous waste guidance, the NYSDEC list of permitted household hazardous waste collection facilities as a starting point, and each county, city, town or regional authority’s own page. 36 New York programs are listed.
• Texas: the Texas Commission on Environmental Quality (TCEQ) household hazardous waste contacts table (dated Sep 22, 2026). 129 Texas programs are listed.

How each listing is checked

• We read each program’s own official page (city, county, utility district or solid waste authority) and record what it says: address, hours or event dates, who can use it, accepted and not-accepted items, limits, fees and whether an appointment is needed.
• A program we can’t confirm on an official source (its own page, or the state agency’s official table) stays off the site until we can.
• When the official page disagrees with a state list or index, the official page wins, and the disagreement is noted on the listing.
• If a source doesn’t state something, we say “not listed by the source.” We don’t guess.
• Accepted-item checkmarks are mapped from the official wording, and the official wording is quoted on each page so you can read it yourself.
• Map locations come from the US Census Geocoder, then OpenStreetMap Nominatim. When a location can’t be matched reliably, we leave the map off and show the official address.

What the labels mean

• Last checked: every listing shows the date we last compared it with its sources, plus links to those sources.
• Collection events drop off the site as soon as they are over.
• Closed / Program ended: shown when the source says so, so you don’t make a wasted trip.

Always call ahead

Programs change hours, limits and accepted items without notice, and sites close for weather and holidays. Call the number on the listing before you load the car. HazmatDrop is not a government agency and does not collect waste.
