• 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 groundwater that contain this element are included.

• 4. CAS index names are those used in the 9th Collective Index.

• 5. Suggested 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.

• 6. Practical 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.

• 5. Suggested 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.

• 6. Practical 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.

• 7. This substance is often called Bis(2-chlorolsopropyl) ether, the name Chemical Abstracts Service applies to its noncommercial isomer, Propane, 2,2"-oxybis[2-chloro- (CAS RN 39638-32-9 )

• 8. Chlordane: This entry includes alpha-chlordane (CAS RN 5103-71-9 ), beta-chlordane (CAS RN 5103-74-2 ), gamma-chlordane (CAS RN 5566-34-7 ), and constituents of chlordane (CAS RN 57-74-9 and CAS RN 12789-03-6 ). PQL shown is for technical chlordane. PQLs of specific isomers are about 20 Og/L by method 8270.

• 9. 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.

• 10. Toxaphene: This entry includes congener chemicals contained in technical toxaphene (CAS RN 8001-35-2 ), i.e., chlorinated camphene.

• 11. Xylene (total): This entry includes o-xylene (CAS RN 96-47-6 ), m-xylene (CAS RN 108-38-3 ), p-xylene (CAS RN. 106-42-3 ), and unspecified xylenes (dimethylbenzenes) (CAS RN 1330-20-7 ). PQLs for method 8021 are 0.2 for o-xylene, and 0.1 for m- or p-xylene. The PQL for m-xylene is 2.0 Og/L by method 8020 or 8260.

• 1. Constituents that may have a class of use based limit in Chapter 8 of the Wyoming Water Quality Rules and Regulations and/or an MCL.

• 2. Constituents that may be used to characterize and compare groundwater quality. These constituents are useful in determining the similarities and/or differences in the composition of water from specific hydrogeologic units and may help show whether particular units are hydraulically separate or connected. These constituents may be used to classify natural waters and help differentiate between natural variability and a release from a landfill.
