Safe Drinking Water Act and Wisconsin groundwater standards are enforceable standards established to protect public health and welfare by limiting the levels of contaminants in drinking water and groundwater. Secondary standards are set to give public water systems some guidance on removing these chemicals to levels that are below what most people will find to be noticeable. However, present methods of measuring taste and odor are still fairly subjective and the task of identifying an unacceptable level for each chemical in different waters requires more study. A standard has been set, however, because silver is used as an antibacterial agent in many home water treatment devices and so presents a potential problem which deserves attention.

Also, some contaminant odors are noticeable even when present in extremely small amounts. However, these tastes and odors may be due to the breakdown of waste products rather than the detergents themselves.
