Inorganic contaminants
31. Inorganic contaminants
Many dissolved metals that contaminate water supplies can be acutely or chronically toxic. Contamination varies widely by geographic location and water source, spurring the need for localized testing. Exposure to even small amounts of inorganic contaminants such as lead, mercury and arsenic have been linked to the development of various cancers, neurological damage and other adverse health effects.
This feature sets maximum safety limits for several inorganic contaminants in drinking water. If necessary, reverse osmosis (RO) systems or Kinetic Degradation Fluxion (KDF) filters can remove dissolved metals.
Water from all faucets, drinking fountains, showers and baths is treated with the following:
