Current through June 17, 2024
004.01 Public
  Drinking Water.
These are surface waters which serve as a public drinking water supply.
	 These waters must be treated (e.g., coagulation, sedimentation, filtration,
	 chlorination) before the water is suitable for human consumption. After
	 treatment, these waters are suitable for drinking water, food processing, and
	 similar uses.
004.01A General
  Criteria.
Wastes or toxic substances introduced directly or indirectly by human
	 activity in concentrations that would degrade the use (i.e., would produce
	 undesirable physiological effects in humans) will not be
	 allowed.
004.01B Numerical
  Criteria.
Numerical criteria for the parameters listed below are not to be
	 exceeded. Any substance introduced directly or indirectly by human activity is
	 not to be allowed to enter surface water if one or more of the following
	 numerical standards would be exceeded. The numerical standards listed below are
	 intended to protect beneficial use of public drinking water supply. If the
	 natural background level of a parameter is greater than the numerical standard,
	 this will not in and of itself prohibit the use of the surface water. If the
	 natural background level of a parameter is greater than the numerical standard
	 listed below, the background level is to be used in place of the numerical
	 criteria.
