The samples were analyzed for metals, nutrients, and other inorganic constituents by the Division of Water Resources laboratory. A summary table of the analytical results, as well as the laboratory reports, field sampling forms, and definitions of laboratory data qualifiers are attached to this letter. The following three constituents were detected above state groundwater standards in both samples from your system: Parameter Units NC Groundwater Standard Results Total Coliform Colony Forming Units per 100 milliliters (CFU/100m1) 1 37 (supply well -influent) 27 (injection well -effluent) Iron Micrograms per Liter (ug/L) 300 660 (supply well -influent) 630 (injection well -effluent) pH Standard Units 6.5 to 8.5 6.0 (supply well -influent) 6.0 (injection well -effluent) D_E NORTH GAROIJNA O. ,flnpnl pl EnWmnmenl$I 0 W III: North Carolina Department of Environmental Quality I Division of Water Resources Washington Regional Office 1943 Washington Square Mall I Washington, North Carolina 27889 252,946.6481 DocuSign Envelope ID: DB2C65E3-FB75-4225-B9E9-A4384FDBA093 Thomas and Lana Brunk July 19, 2021 Page 2 of 2 These exceedances should not affect the use of the wells for your geothermal heat pump system; however, it is recommended before using the water from these wells for personal consumption that you consult with the Craven County Environmental Health Depailment.

MIC:Fecal Coliform-Q1-Sample exceeded holding time prior to receipt at lab. NCDEQ-WSS-Chemistry Lab Data Qualifiers Al The reported value is an average, where at least one result is qualified with a "U". The PQL is used for the qualified result(S) to call B1 Coliform-Countable membranes with less than 20 colonies. Reported value is estimated or is a total of the counts on all filters repor B2 Coliform-Counts from all filters were zero. The value reported is based on the number of colonies per 100 ml that would have been B3 Coliform-Countable membranes with more than 60 or 80 colonies. The value reported is calculated using the count from the smaller B4 Coliform-Filters have counts of both >60 or 80 and <20. Reported value is estimated or is a total of the counts on all filters reported B5 Coliform-Too many colonies were present; too numerous to count (TNTC). TNTC is generally defined as >150 colonies.

G4 BOD-Evidence of toxicity. This is generally characterized by a significant increase in the BOD value as the sample concentration de G5 BOD-The glucose/ glutamic acid standard exceeded the range of 198 ± 30.5 mg/L. G7 BOD-Less than 1 mg/L DO remained for all dilutions set. The reported value is an estimated greater than value and is calculated foi G8 BOD-Oxygen usage is less than 2 mg/L for all dilutions set. The reported value is an estimated less than value and is calculated for G9 BOD-The DO depletion of the dilution water blank produced a negative value.
