Can I drink water that exceeds health advisory guidelines?
It is not recommended that you drink water exceeding the health advisory guidelines, but the choice is ultimately yours. The health advisory guidelines are generally based on a lifetime of exposure to the risk, so limited or short term exposure generally will not cause acute or chronic illness. The effect on any person will depend on the type and degree of contamination, the amount of water consumed and the person’s resistance to that contamination, which depends on age and other coexisting health problems.
