001 The following narrative standards shall apply to ground waters in the State:
001.01 Wastes, toxic substances, or any other pollutant (alone or in combination with other pollutants) introduced directly or indirectly by human activity shall not be allowed to enter ground water:
001.02 Any pollutant introduced directly or indirectly by human activity that would impair beneficial uses of ground water due to unacceptable color, corrosivity, odor, or any other aesthetic characteristic shall not be allowed.
001.01A If beneficial uses of ground water would be impaired or public health and welfare would be threatened; or
001.01B If beneficial uses of hydrologically connected ground waters or assigned uses of surface waters would be impaired.
002 Numerical standards (maximum contaminant levels) for the parameters listed below shall apply to ground waters in the State in accordance with Chapters 2 and 3. Any substance introduced directly or indirectly by human activity shall not be allowed to enter ground water if one or more of the following numerical standards would be exceeded ("reserved" indicates that a standard will be promulgated for this parameter):
Public Health Parameters
Maximum Contaminant Levels
7.00E+06 fibers/liter with fiber length > 10 microns
Dichloromethane (Methylene Chloride)
Nitrate (as N)
Nitrite (as N)
Polychlorinated biphenyls (PCBs)
Total Trihalomethanes (TTHMs)
Gross alpha particle activity (including radium-226 but excluding radon and uranium)
Gross beta particle activity
Combined radium-226 and radium-228
Other Parameters Affecting Use
6.5 - 8.5 standard pH units
Total Dissolved Solids (TDS)
003 The numerical standards listed in 002 above are intended to protect beneficial uses of ground water. If the background level of a parameter is greater than the numerical standard, this shall not in and of itself prohibit the use of the ground water.
004 If the background level of a parameter is greater than the numerical standard listed in 002 above, the background level shall be used as the numerical standard.
