1)TOC elevations were surveyed by SEPI Engineering in September 2009.
2)MW-5 was damaged prior to the November 2013 event and a water level was not able to measured during the event.
3)MW-5 was resurveyed by Dewberry Engineers Inc. on May 27, 2014, after being repaired on March 5, 2014.

ND = Not detected at the stated reporting limit
J = estimated concentration
B = blank-qualified resultdry = no flowing water at time of sampling
-- = no data
MDL = Method Detection Limit
Blanks = field, trip and method blanks
Surface Water Standards = SW Standards are WS Standards (Ellerbee Creek is a WS-IV Classification) or Freshwater Aquatic Life Standards if no WS Standard exists.
SWS Reporting Limit = NCPQL from 09/14/94 through 12/05/06 and NCSWSL for 05/30/07 and later
Shaded = Concentrations above the applicable Surface Water Standards have been shaded.
# = Freshwater Aquatic Life Standards
* = Standard is a Narrative Standard
