Germanium is a metalloid used in electronics. It can enter water from industrial processes. While not essential for health, high levels may cause adverse effects.

Discovered in 1886, germanium is a metalloid element widely used in modern electronics. It can enter water supplies through mining operations, metal smelting, and industrial waste disposal. While not currently regulated in drinking water by the EPA, germanium levels are typically measured in parts per billion (ppb). Its presence in water is primarily due to human activities rather than natural occurrence. Research on potential health effects from water exposure is limited, emphasizing the need for further study.
