1The regulatory requirements
				  pertain only to the list of substances; the right hand columns (Methods and
				  PQL) are given for informational purposes only. See also footnotes 5 and
				  6.
2Common names are those widely
				  used in government regulations, scientific publications, and commerce; synonyms
				  exist for many chemicals.
3Chemical Abstracts Service
				  registry number. Where "Total" is entered, all species in the groundwater that
				  contain this element are included.
4CAS index names are those used in
				  the 9th Collective Index.
5Suggested Methods refer to
				  analytical procedure numbers used in EPA Report SW-846 "Test Methods for
				  Evaluating Solid Waste", third edition, November 1986, as revised, December
				  1987. Analytical details can be found in SW-846 and in documentation on file at
				  the department. CAUTION: The methods listed are representative SW-846
				  procedures and may not always be the most suitable method(s) for monitoring an
				  analyte under the regulations.
6Practical Quantitation Limits
				  (PQLs) are the lowest concentrations of analytes in groundwaters that can be
				  reliably determined within specified limits of precision and accuracy by the
				  indicated methods under routine laboratory operating conditions. The PQLs
				  listed are generally stated to one significant figure. PQLs are based on 5 mL
				  samples for volatile organics and 1 L samples for semivolatile organics.
				  CAUTION: The PQL values in many cases are based only on a general estimate for
				  the method and not on a determination for individual compounds; PQLs are not a
				  part of the regulation.
