Mercury is highly toxic.
If you drop and break an old-fashioned mercury fever thermometer in a sink, its mercury could go down the drain and get into the wastewater that flows through sewers to the treatment plant. However, the treatment process cannot remove all traces of mercury, so some will end up in local waters, causing harm to aquatic life.
Because of this, the sale of mercury fever thermometers was banned in California years ago. But some people still have them at home. Digital thermometers are much better for the environment.
That’s why Central San will give a free digital solar (no batteries!) thermometer to our customers who bring an old mercury-filled thermometer to our Household Hazardous Waste Collection Facility for safe disposal!
