Mercury is a silvery liquid. If you have a thermometer with mercury in it, bring it to the annual Household Hazardous Waste Day, the Regional Hazardous Waste Collection Sites at the Colrain and Conway transfer stations, or the District Office at 117 Main St., 2nd Floor, Greenfield. We offer a free digital fever thermometer in exchange. (One per household.) If the thermometer has red or blue liquid, it does not contain mercury and may be put in the trash. Thermostats must be brought to the annual Household Hazardous Waste Day, the Regional Hazardous Waste Collection Sites at the Colrain and Conway transfer stations, or the District Office at 117 Main St., 2nd Floor, Greenfield.
