1 The 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.
2 Common names are those
							 widely used in government regulations, scientific publications, and commerce;
							 synonyms exist for many chemicals.
3 Chemical Abstracts
							 Service registry number. Where "Total" is entered, all species in the ground
							 water that contain this element are included.
4 CAS index names are
							 those used in the 9th Cumulative Index.
5 Suggested Methods refer
							 to analytical procedure numbers used in EPA Report SW-846 "Test Methods for
							 Evaluating Solid Waste", third edition and updates, as incorporated by
							 reference in section
							 66260.11. Analytical details can
							 be found in SW-846 and in documentation on file at the agency. The packed
							 column gas chromatography methods 8010, 8020, 8030, 8040, 8060, 8080, 8090,
							 8110, 8120, 8140, 8150, 8240, and 8250 were promulgated methods through Update
							 IIB of SW-846 and, as of Update III, the Agency has replaced these methods with
							 "capillary column GC methods", as the suggested methods.
6 Practical Quantitation
							 Limits (PQLs) are the lowest concentrations of analytes in ground waters 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. 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.
7 Polychlorinated
							 biphenyls (CAS RN 1336-36-3); this category contains congener chemicals,
							 including constituents of Aroclor-1016 (CAS RN 12674-11-2); Aroclor-1221 (CAS
							 RN 11104-28-2), Aroclor-1232 (CAS RN 11141-16-5), Aroclor-1242 (CAS RN
							 53469-21-9), Aroclor-1248 (CAS RN 12672-29-6), Aroclor-1254 (CAS RN
							 11097-69-1), and Aroclor-1260 (CAS RN 11096-82-5). The PQL shown is an average
							 value for PCB congeners.
8 This category contains
							 congener chemicals, including tetrachlorodibenzo-p-dioxins (see also
							 2,3,7,8-TCDD), pentachlorodibenzo-p-dioxins, and hexachlorodibenzo-p-dioxins.
							 The PQL shown is an average value for PCDD congeners.
9 This category contains
							 congener chemicals, including tetrachlorodibenzofurans,
							 pentachlorodibenzofurans, and hexachlorodi-benzonfurans. The PQL shown is an
							 average value for PCDF congeners.
