Notes:
0 -Bold highlighted concentration indicates exceedance of the 15A NCAC 02L Standard, Appendix 2, April 1, 2013.
NE = Not established
ug/I = microgram per liter
mg/I = milligram per liter
< = concentration not detected at or above the reporting limit
= Interim Maximum Allowable Concentrations (IMACs) of the 15A NCAC 02L Standard, Appendix 1, April 1, 2013.
j = Indicates concentration reported below Practical Quantitation Limit (PQL), but above Method Detection Limit (MDL) and therefore concentration is estimated.
