* South Dakota does not specifically refer to the groundwater quality standards as "Cleanup Standards" but in a practical sense they are used as such.

** Compliance to the 0.1mg/L level is required if the contamination is within the radius of influence of a well or within a delineated well head protection area, unless a variance is obtained. Otherwise the compliance level is10mg/L.

*** No particular method is specified however, methods used must conform with "Standard Methods for Examination of Water and Waste Water" and "EPA Methods, Methods for Chemical Analysis of Waters and Wastes."
