Section 724.APPENDIX I   Groundwater Monitoring List

 

a)         Common names are those widely used in government regulations, scientific publications and commerce; synonyms exist for many chemicals.

 

b)         "CAS RN" means "Chemical Abstracts Service Registry Number".  Where "total" is entered, all species in the groundwater that contain this element are included.

 

c)         CAS index names are those used in the 9th Cumulative index.

 

d)         PCBs (CAS RN 1336-36-3).  This category contains congener chemicals, including constituents 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).

 

e)         PCDDs.  This category includes congener chemicals, including tetrachlorodibenzo-p-dioxins (see also 2,3,7,8-TCDD), pentachlorodibenzo-p-dioxins and hexachlorodibenzo-p-dioxins.

 

f)         PCDFs.  This category contains congener chemicals, including tetrachlorodibenzofurans, pentachlorodibenzofurans, and hexachlorodibenzofurans.
