The MCL for manganese, which affects aesthetic quality, is set at?

The maximum contaminant level (MCL) for manganese has been established at 0.05 mg/l to protect the aesthetic quality of drinking water. Manganese can cause unpleasant tastes and staining in water, affecting the overall consumer perception and willingness to use the water.

Setting the MCL at this level helps ensure that water suppliers maintain water quality that is not only safe but also visually appealing and palatable, minimizing potential health risks associated with higher concentrations. In practical terms, this means water treatment facilities must monitor and control manganese levels to comply with regulations, ensuring consumer satisfaction and health safety.
