Note 1: Constituent is retained as a COPC if analytical method detection limit or concentration is greater than the groundwater criteria
Note 2: Constituent is retained as a COPC if no groundwater criteria
Note 3: Hexavalent Chromium concentration is greater than EPA screening value for tapwater (0.035 ug/L). See Table 10-3 (USEPA Regional
Screening Levels [RSLs] rev., June 26, 2015)
Note 4: Hexavalent Chromium concentration is less than EPA screening value for tapwater (0.035 ug/L). See Table 10-3 (USEPA Regional Screening
Levels [RSLs] rev., June 26, 2015)
Note 5: Speciation Sample date does not match listed sample collection date

Notes
- Bold highlighted concentration indicates exceedance of the 15A NCAC 02L, Appendix 2, April 1, 2013
F .e$ - Indicates support/rationale for soil COPC attributable to coal ash.
iiiiij - Indicates constituent is not
a soil COPC attributable to coal ash.
