Mercury Thermometer Exchange Program Mercury is rising in the Bay! Exchange your mercury thermometer for a mercury-free thermometer at no charge today! To protect our water environment and comply with the upcoming mercury discharge regulations, Union Sanitary District is taking an active role in reducing mercury discharges. Mercury, the highly toxic metal found in many glass thermometers, is polluting San Francisco Bay. Recent studies show relatively high levels of mercury accumulating in fish, clams, and other organisms in the Bay. When the glass mercury thermometers break, the mercury ultimately finds its way into the San Francisco Bay, usually through your home sinks. In fact, the half-gram of mercury in a thermometer is enough to pollute 5 million gallons of bay water!
The Union Sanitary District's Wastewater Treatment Plant processes can only remove a small portion of the mercury in wastewater; The best solution to protect water quality is to prevent mercury from entering the wastewater system. Mercury for Hg-Free is a program to eliminate one common source of mercury; We are offering to exchange your mercury thermometer for a new type of thermometer at no cost to you! The mercury-free thermometer is equally accurate and easy to use. We will safely dispose of mercury thermometers to prevent them from contaminating our waters.
