What is the legal limit of Hexavalent Chromium in drinking water?
10 parts per billion
The MCL for Hexavalent Chromium in drinking water is 10 parts per billion (ppb). By law, California is required to adopt drinking water standards that are no less stringent than the United States Environmental Protection Agency’s federal standards.
Can Hexavalent Chromium be filtered from water?
Faucet and countertop filters using activated carbon are not capable of removing or reducing Hexavalent Chromium. Water purification (reverse osmosis), not just simple filtration, will remove Hexavalent Chromium from drinking water.
How is Hexavalent Chromium removed from drinking water?
Reverse Osmosis will remove Hexavalent Chromium from drinking water.
Is chromium harmful in drinking water?
It is not harmful unless levels are very high. Chromium 0 and VI are more harmful and there are health risks with exposure. People who drink water with chromium over the maximum acceptable concentration (MAC) for many years can have health problems like: allergic dermatitis.
Does Brita filter remove chromium?

How do you lower chromium levels in water?
Chromium in Drinking Water The best way to reduce chromium-6 is through a reverse osmosis system. It is also known that distillation and anion exchange methods are effective. *Maximum Contaminant Level (MCL): The highest level of a contaminant that is allowed in drinking water.
How much chromium is in drinking water in Canada?
Total chromium levels in unpolluted surface water are typically below 1 µg/g. CAREX Canada’s estimates indicate that chromium [VI] levels in drinking water may result in an increased risk of cancer at a population level ( moderate data quality ).
Is there any hexavalent chromium in Canada?
Hexavalent chromium was not included in other Canadian government guidelines, standards, or chemical listings reviewed.
Where does hexavalent chromium occur in drinking water?
hexavalent chromium dissolved in groundwater. Recent sampling of drinking water sources throughout California suggests that hexavalent chromium may occur naturally in groundwater at many locations. Naturally occurring hexavalent chromium may be associated with serpentinite-containing rock or chromium containing geologic formations. History of
What are the risks of chromium in drinking water?
CAREX Canada’s estimates indicate that chromium [VI] levels in drinking water may result in an increased risk of cancer at a population level ( moderate data quality ). Average levels of chromium [VI] in air near industrial areas may be 10 – 45 times higher than those in non-industrial areas. [ 6]
