March 17, 2022 Weld County 1150 O Street Greeley, CO 80631 RE: Water Supply Sampling To Whom It Concerns, RECEIVED MAR 3 1 2022 WELD COUNTY COMMISSIONERS Mallard Exploration (Mallard) contracted Quandary Consultants, LL (Quandary) to collect a subsequent water sample from your water well (permit 276779 -/receipt 3626257) in Township 9N, Range 60W, Section 34, Weld County, Colorado, on March 3, 2022. The sampling activities were conducted per Rule 609 requirements set forth by the Colorado Oil and Gas Conservation Commission (COG). The water sample was collected in laboratory -supplied containers and submitted to Pace Analytical in Mt Juliet, Tennessee for analysis of the required water quality parameters, The water well sample analytical results from Pace can be used to determine the overall water quality in your water well (Attachment 2) and a summary table of the results are found in Attachment 1, If you have questions regarding the general water quality parameters in your water well, please refer to the Water Quality Control Commission of the Colorado Department of Public Health and Environment (CDPHE) drinking water standards. While the standards are for regulation of public water systems and do not apply to private water wells, they can be used for general comparison and can be accessed at the following intend resource: https:/ www.coiorado. ov/jaciiic/cdphe/wacer-quality-cunt_rol--comet fission-regulat on,s 1. Select "Regulation 41: The Basic Standards for Ground Water Additionally, a booklet titled How Well Do You Know Your Water Well? has been prepared in cooperation with the CO CC, the CDPHE, and the Colorado Division of Water Resources, This booklet can be accessed at the following resource: ht,tp:i/c:o cc.staite.QQ„us'dpc ne ts/Iibrary/Pres ptationsi encral/waterwcllbookIet.pdf A copy of the analytical results will be submitted to Arthur Koepsell, Environmental Data Analyst with the COGCC (303-894-2100 X5148). Mallard appreciates your cooperation in this sampling effort. If you have any questions, please contact me at 720-543-7959.

This Is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample D, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On -Site Data, Sampling Collection Dates/Ti mes, a n d Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions MDL ND RDL Rec. RPD SDG (S) Analyte Dilution Limits Original Sample Qualifier Result Uncertainty (Radiochemistry) Case Narrative (Cn) Quality Control Summary (Oc) Sample Chain of Custody (Sc) Sample Results (Sr) Sample Summary (Ss) Qualifier Method Detection Limit. Not detected at the Reporting Limit (or MDL where applicable). Reported Detection Limit, Recovery. Relative Percent Difference. Sample Delivery Group. Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. Not detected at the Reporting Limit (or MDL where applicable). The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. if the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than I is used in this field, the result reported has already been corrected for this factor. These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analyses recovered or duplicated within these ranges. The non -spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be Included within the reported SDG. This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative If applicable. The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state "ND" (Not Detected) or "BDL" (Below Detectable Levels). The information In the results column should always be accompanied by either an MDL (Method Detection Limit) or ROL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Confidence level of 2 sigma. A brief discussion about the included sample results, including a discussion of any non -conformances to protoco I observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. This section of the report Includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample, The header line of each analysis section for each sample will provide the name and method number for the analysis reported. This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Description B J J3 V The same analyte is found in the associated blank, The identification of the analyte is acceptable; the reported value is an estimate. The associated batch QC was outside the established quality control range for precision. The sample concentration Is too high to evaluate accurate spike recoveries. c 4 5, 4 ACCREDITATIONS & LOCATIONS Pace Analytical Nationa Alabama Alaska Arizona Arkansas California Colorado Connecticut Florida Georgia Georgia' Idaho Illinois Indiana Iowa Kansas Kentucky' 6 Kentucky' Louisiana Louisiana Maine Maryland Massachusetts Michigan Minnesota Mississippi Missouri Montana 12065 Lebanon Rd Mount Juliet, TN 37122 40660 17-026 AZ0G12 88-0469 2932 TN00003 PH -0197 E87487 NELAP 923 TN00003 200008 C -TN -01 364 E-10277 KY90D10 16 Al30792 LA018 TN00003 324 M-TNDD3 995E 047-999-395 TN00003 340 CERT00B8 Nebraska Nevada New Hampshire New Jersey—NELAP New Mexico' New York North Carolina North Carolina' North Carolina 3 North Dakota Ohio —YAP Oklahoma Oregon Pennsylvania Rhode Island South Carolina South Dakota Tennessee" 4 Texas Texas Utah Vermont Virginia Washington West Virginia Wisconsin Wyoming AAA —.
