For samples with incomplete water quality results (missing one or more parameter), samples are divided into two classes based on DO levels. For those samples that do not have DO data, but have NO3, Mn, Fe, and SO4, redox process and category is assigned but amended with additional information regarding the lack of DO data. For those samples that do not have data for either NO3, Mn, Fe, or SO4, samples are classified as "Indeterminate" Question marks (?) indicate that the process is likely in that direction though the calculation did not have enough information to completely assign a category. Calculations were made using the spreadsheet provided by the United States Geological Survey. Method was conducted following the report: An Excel Workbook for Identifying Redox Processes in Ground Water Open File Report 2009-1004.

Federal (USFWS Raleigh Field Office) Status and Federal Record Status obtained from U.S. Fish & Wildlife Service, Endangered Species, Threatened Species, Federal Species of Concern and Candidate Species website, http://www.fws.gov/raleigh/species/cntylist/nc_counties.html Page 1 of 3 Table 12-8. Threatened and Endangered Species in Rowan County 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 See below. Protection Act. FSC = Federal Species of FSC is an informal term. It is not defined in the federal Endangered Species Act. In North Carolina, the Concern 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 A taxon that is threatened due to similarity of appearance with another listed species and is listed for its Similarity of Appearance 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. Definitions of Federal Status Codes cont.: Bald and Golden Eagle 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 more information, visit http://www.fws.gov/migratorybirds/baldeagle.htm Threatened due to similarity of appearance(T(S/A)): 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 Federal 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. 2 of 3 Table 12-8. Threatened and Endangered Species in Rowan County 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). SR = Significantly Rare 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 small numbers and has been determined by the N.C. Natural Heritage Program to need monitoring. 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 NCAC48F .0401). SR-L = Significantly Rare Limited Any species not listed by the N.C. Plant Conservation Program as Endangered, Threatened, or Candidate, which is rare in North Carolina, generally with 1-100 populations in the state, frequently substantially reduced in numbers by habitat destruction (and sometimes also by direct exploitation or disease). SR-T = Significantly Rare Throughout The species is rare throughout its range (fewer than 100 populations total). Definition of State Codes cont.: 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 = Peripheral 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 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. Definitions of County Record Status: Current Current - the species has been observed in the county within the last 50 years. Historic Historic - the species was last observed in the county more than 50 years ago. Probable/potential 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.

Health PSRG and NC Protect GW PSRG: For solid matrix samples such as soil, ash, sediment, partially weathered rock, and bedrock, the North Carolina Department of Environment and Natural Resources Division of Waste Management Soil Remediation Goals Table (March 2015) - Preliminary Industrial Health Based PSRG and Protection of Groundwater PSRGsare shown for comparison purposes. 3. No PSRG for total chromium is currently available. As a surrogate, the PSRG for trivalent chromium (Cr III) is given for comparison purposes only. 4. NC 02B Criteria: North Carolina Department of Environment and Natural Resources Division of Water Resources 15A NCAC 02B Surface Water Standards and Protective Values & EPA National Reccomended Water Quality Criteria. 5. INC 02L GWQS and NC 02L IMAC: North Carolina Department of Environment and Natural Resources Division of Water Resources 02L Groundwater Quality Standards and Interim Maximum Allowable Concentrations (IMACs). April 2013 6. The IMAC value is shown where there is no applicable 02L standard. Appendix #1 of 15A NCAC Subchapter 02L Classifications and Water Quality Standards Applicable to the Groundwaters of North Carolina, lists Interim Maximum Allowable Concentrations (IMACs). The IMACs were issued in 2010 and 2011, however NCDENR has not established a 02L standard for these constituents as described in 15A NCAC 02L.0202(c). For this reason, IMACs are noted in this report for reference only. 7. For groundwater samples, nitrate + nitrite is reported due to preservation of groundwater sample. QUALIFIERS: "<^ symbol followed by a number and qualifier indicates that the result is less than the reporting limit shown. U: Not detected above the reporting limit (value to left of the " U"). J: Estimated concentration. J+: Estimated concentration, biased high. J-: Estimated concentration, biased low. mg/kg - milligrams per kilogram (ppm equivalent) ug/I - micrograms per liter (ppb equivalent) pCi/L: pico-curies per liter ug/mL: micrograms per milliliter
