US EPA: Mercury use: Business or Commercial Establishments
Description
Mercury use in the business sector usually falls into three main categories: mercury used in batteries, lamps, or switches. There are a number of ways mercury can enter the wastewater stream of a business. When a mercury-containing product such as a thermometer is broken over a sink or improperly cleaned up after a spill, the mercury could get flushed down the drain. Mercury may also be present in a business facility’s sewer pipes and traps from historical use of mercury.
