Can wastewater treatment plants solve the mercury issue?
Wastewater treatment plants are designed to treat wastewater containing conventional pollutants such as human and food waste. Heavy metals, including mercury, are not completely removed by the treatment process. As a result, some mercury remains in the treated wastewater discharged to the South San Francisco Bay or in the biosolids, which are used for landfill cover.
