'Depths measured from ground surface during well installation and reported on the monitoring well construction logs
2Well depths measured by SynTerra, June 30 and July 1, 2015
3 Where total depth was not measured well screen elevations were estimated, based on the difference between TOC and ground surface elevations.
Monitoring well coordinate and elevation data for newly installed wells from surveys provided by McKim & Creed, completed 8/14/15. McKim and Creed also verified survey location at several existing locations.
* No boring logs available for "CHATH" piezometers, monitoring zone assigned based on depths and comparison to nearby sample locations with boring logs

Bold color highlighted concentrations indicate highest exceedance of the EPA Mid -Atlantic Risk Assessment regional screening levels for soil, June 2015, for the category listed below:
O - Soil RSL - Industrial Health
0 - Soil RSL - Residential Health
- Soil RSL - Protection of Groundwater
= Percent
mg/kg = milligrams per kilogram
NE = Not established
S.U. = Standard Units
CUP = Duplicate
j = indicates concentration reported below Practical Quantitation Limit (PQL), but above Method Detection Limit (MDL) and therefore concentration is estimated.
< = concentration not detected at or above the reporting limit.

NotesL
Bold color highlighted concentrations indicate highest exceedance of the EPA Mid -Atlantic Risk Assessment regional screening levels for soil, June 26, 2015, for the category listed below:
- Concentration Greater than Soil RSL - Residential -Use Scenario Note 1: COPC is retained if analytical method detection limit or concentration is greater than soil RSL
- Concentration Greater than Soil RSL - Industrial -Use Scenario Note 2: COPC is retained if no soil RSL
- Detection limit Greater Than Residential Soil RSL
- Detection Limit Greater Than Industrial Soil RSL
- Indicates support/rationale for soil COPC potentially attributable to coal ash.
O- Indicates constituent is not a soil COPC potentially attributable to coal ash.
S.U. = Standard Units
mg/kg = milligram per kilogram
< = concentration not detected at or above the reporting limit.
j = indicates concentration reported below Practical Quantitation Limit (PQL), but above Method Detection Limit (MDL) and therefore concentration is estimated
DUP = Duplicate

Notes
Bold color highlighted concentrations indicate highest exceedance of the EPA Mid -Atlantic Risk Assessment regional screening levels (RSLs) for soil, June 26, 2015, for the category listed below:
- Concentration Greater than Soil RSL - Residential -Use Scenario Note 1: COPC is retained if analytical method detection limit or concentration is greater than soil RSL
- Concentration Greater than Soil RSL - Industrial -Use Scenario Note 2: COPC is retained if no soil RSL
- Detection limit Greater Than Residential Soil RSL
- Detection Limit Greater Than Industrial Soil RSL
0 -Indicates support/rationale for soil COPC potentially attributable to coal ash.
- Indicates constituent is not a soil COPC potentially attributable to coal ash.
S.U. = Standard Units
mg/kg = milligram per kilogram
< = concentration not detected at or above the reporting limit.
j = indicates concentration reported below Practical Quantitation Limit (PQL), but above Method Detection Limit (MDL) and therefore concentration is estimated
DUP = Duplicate

US FWS Updated: 3-25-2015 https://www.fws.gov/raleigh/species/cntylist/chatham.html
Definitions of Federal Status Codes:
E = endangered. A taxon "in danger of extinction throughout all or a significant portion of its range."
T = threatened. A taxon "likely to become endangered within the foreseeable future throughout all or a significant portion of its range."
C = candidate. A taxon under consideration for official listing for which there is sufficient information to support listing. (Formerly "Cl" candidate species.)
BGPA =Bald and Golden Eagle Protection Act. See below.
FSC=Federal Species of Concern. FSC is an informal term. It is not defined in the federal Endangered Species Act. In North Carolina, the Asheville and Raleigh Field Offices of the US Fish and Wildlife Service (Service) define Federal Species of
Concern as those species that appear to be in decline or otherwise in need of conservation and are under consideration for listing or for which there is insufficient information to support listing at this time.Subsumed under the term "FSC" are all
species petitioned by outside parties and other selected focal species identified in Service strategic plans, State Wildlife Action Plans, or Natural Heritage Program Lists.
T(S/A) = threatened due to similarity of appearance. A taxon that is threatened due to similarity of appearance with another listed species and is listed for its protection. Taxa listed as T(S/A) are not biologically endangered or threatened and are
not subject to Section 7 consultation. See below.
EXP = experimental population. A taxon listed as experimental (either essential or nonessential). Experimental, nonessential populations of endangered species (e.g., red wolf) are treated as threatened species on public land, for consultation
purposes, and as species proposed for listing on private land.
P = proposed. Taxa proposed for official listing as endangered or threatened will be noted as "PE" or "PT", respectively.
Bald and Golden Eaale Protection Act (BGPA):
In the July 9, 2007 Federal Register( 72:37346-37372), the bald eagle was declared recovered, and removed (de -listed) from the Federal List of Threatened and Endangered wildlife. This delisting took effect August 8,2007. After delisting, the
Bald and Golden Eagle Protection Act (Eagle Act) (16 U.S.C. 668-668d) becomes the primary law protecting bald eagles. The Eagle Act prohibits take of bald and golden eagles and provides a statutory definition of "take" that includes "disturb".
The USFWS has developed National Bald Eagle Management Guidelines to provide guidance to land managers, landowners, and others as to how to avoid disturbing bald eagles. For mor information, visit
http://www.fws.gov/migratorybirds/baideagle.htm
Threatened due to similarity of aooearance(T(S/A)1:
In the November 4, 1997 Federal Register (55822-55825), the northern population of the bog turtle (from New York south to Maryland) was listed as T (threatened), and the southern population (from Virginia south to Georgia) was listed as
T(S/A) (threatened due to similarity of appearance). The T(S/A) designation bans the collection and interstate and international commercial trade of bog turtles from the southern population. The T(S/A) designation has no effect on land
management activities by private landowners in North Carolina, part of the southern population of the species. In addition to its official status as T(S/A), the U.S. Fish and Wildlife Service considers the southern population of the bog turtle as a
Federal species of concern due to habitat loss.
Definitions of Record Status:
Current - the species has been observed in the county within the last 50 years.
Historic - the species was last observed in the county more than 50 years ago.
Obscure - the date and/or location of observation is uncertain.
Incidental/migrant - the species was observed outside of its normal range or habitat.
Probable/potential - the species is considered likely to occur in this county based on the proximity of known records (in adjacent counties), the presence of potentially suitable habitat, or both.
Definition of State Codes:
CODE/ STATUS DEFINITION
E=Endangered Any native or once -native species of wild animal whose continued existence as a viable component of the State's fauna is determined by the Wildlife Resources Commission to be in jeopardy or any species of
wild animal determined to be an 'endangered species' pursuant to the Endangered Species Act. (Article 25 of Chapter 113 of the General Statutes; 1987).
T=Threatened Any native or once -native species of wild animal which is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range, or one that is designated as a
threatened species pursuant to the Endangered Species Act. (Article 25 of Chapter 113 of the General Statutes; 1987).
SC=Special Concern Any species of wild animal native or once -native to North Carolina which is determined by the Wildlife Resources Commission to require monitoring but which may be taken under regulations adopted under the
provisions of this Article. (Article 25 of Chapter 113 of the General Statutes; 1987).
Any species which has not been listed by the N.C. Wildlife Resources Commission as an Endangered, Threatened, or Special Concern species, but which exists in the state (or recently occurred in the state) in
SR=Significantly Rare small numbers and has been determined by the N.C. Natural Heritage Program to need monitoring. Significantly Rare species include "peripheral" species, whereby North Carolina lies at the periphery of the
species' range (such as Hermit Thrush), as well as species of historical occurrence with some likelihood of re -discovery in the state. Species considered extirpated in the state, with little likelihood of re-
discovery, are given no N.C. Status (unless already listed by the N.C. Wildlife Resources Commission as E, T, or SC).
SR-G=Game Animal Species is a game animal or a furbearer, and therefore (by law) cannot be listed for State protection as E, T, or SC.
SC-V=Special Concern -Vulnerable "Any species or higher taxon of plant which is likely to become a threatened species within the foreseeable future"(NCAC 02 NCAC 48F .0401).
SC-H=Special Concern -Historical "Any species or higher taxon of plant that occurred in North Carolina at one time, but for which all known populations are currently considered to be either historical or extirpated." "(NCAC 02 NCAC 48F .0401).
SR-L= Significantly Rare Limited The range of the species is limited to North Carolina and adjacent states (endemic or near endemic). These are species that may have 20-50 populations in North Carolina, but fewer than 100 populations
rangewide. The preponderance of their distribution is in North Carolina and their fate depends largely on conservation here.
SR-T=Significantly Rare The species is rare throughout its range (fewer than 100 populations total).
Thrnuahnut
SR-D=Significantly Rare Disjunct The species is disjunct to North Carolina from a main range in a different part of the country or world.
SR-P=Significantly Rare The species is at the periphery of its range in North Carolina. These species are generally more common somewhere else in their ranges, occurring in North Carolina peripherally to their main ranges, mostly in
Peripheral habitats which are unusual in North Carolina.
SR-O=Significantly Rare Other The range of the species is sporadic or cannot be described by the other Significantly Rare categories
W= Watch List Any other species believed to be rare and of conservation concern in the state but not warranting active monitoring at this time
