Geochemistry and Environmental Tracer Data for Groundwater, Stream Water, and Sediment from the East Mancos River, Colorado, 2023: U.S. Geological Survey data release, https://doi.org/10.5066/P9NKUNUO https://doi.org/10.5066/P9NKUNUO This U.S. Geological Survey (USGS) data release contains data from stream water, groundwater, and stream sediment samples collected in August 2023 in the East Mancos River watershed in southwestern Colorado. Data were collected as part of a study aimed at identifying sources of elevated metal concentrations in the stream. Eighteen streambank wells were installed in pairs at nine locations to capture the emerging groundwater from the left and right banks (relative to downstream-facing direction) and a synoptic sampling campaign was conducted to quantify stream metal loads. A continuous, instream injection of sodium bromide (NaBr) was initiated at the head of the ~17 km study reach prior to the synoptic sampling campaign and maintained throughout the duration of the study. Bromide concentrations were subsequently used to determine streamflow in the upper ~2.7 km of the stream using the tracer-dilution method. Streamflow was quantified for tributaries and locations farther downstream using data from a series of sodium chloride slug additions wherein specific conductivity readings were used as a surrogate for the tracer concentration. Stream and groundwater samples, including the wells and inflows from the left (LBI) and right (RBI) banks, were collected mainly in the upper ~0.9 km of the stream course (primary study reach). Environmental tracer data were collected to better understand groundwater flowpaths to the stream. Stream sediment samples, including some ferricrete samples, were also collected to help identify potential instream and near-stream metal sources. The main purpose of this work was to obtain a detailed stream metal loading profile within the primary study reach and distinguish mining-related sources from natural background sources of loading. This information is valuable for assessing the potential benefits of mine remediation activities within the watershed. 2023 2024 ground condition Complete None planned -108.23292 -108.09972 37.42242 37.36360 ISO 19115 Topic Category environment biota USGS Thesaurus abandoned mines and quarries mine drainage geochemistry groundwater and surface-water interaction Marine Realms Information Bank (MRIB) keywords chemical tracer studies groundwater geochemistry none U.S. Geological Survey USGS Mineral Resources Program MRP Geology, Geophysics, and Geochemistry Science Center GGGSC streambank well synoptic sampling tracer injection sulfide-weathering USGS Metadata Identifier USGS:63a10af6d34e0de3a1f27966 Geographic Names Information System East Mancos River Helmet Peak Spiller Peak Burwell Peak Gibbs Peak Red Arrow Dome Caviness Mountain Fall Creek San Juan National Forest None.

Denver CO 80225 United States 303-236-1812 amanning@usgs.gov Users should note that some software systems could truncate values within this dataset, particularly values ending with zero(s). No formal attribute accuracy tests were conducted No formal logical accuracy tests were conducted Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. All locations were obtained using hand-held GPS with standard accuracy in datum World Geodetic System 1984 (WGS84) No formal positional accuracy tests were conducted Sample Collection and Analyses were obtained as follows: Groundwater Well Installation: Nine pairs of streambank wells were installed prior to all sampling activities, each pair including one well on either side of the stream in approximately the same location. Boreholes were drilled to an average depth of roughly 1 m using a hand-held gas-powered rock coring drill. Wells were installed in the open boreholes with 1-inch diameter slotted polyvinyl chloride (PVC) well screen. Water Sample Collection: Stream sites had narrow cross sections, allowing for the collection of stream samples by the simple grab technique. Inflow samples were also collected by the simple grab technique, and well samples were collected using a peristaltic pump. Field parameters including specific conductance, pH, water temperature, and dissolved oxygen concentration were measured using an Orion Star A329 meter with Ross pH electrode (3-point calibrations with 4.01, 7.00, and 10.01 buffers performed at least daily). Field parameters were measured in-situ and sample filtration was performed on-site at the time of collection for all samples except those collected during the main synoptic sampling event on the morning of August 27, 2023; for these synoptic samples, field parameters (except for temperature) were measured and sample filtration performed at a central field-processing location. Separate sample aliquots were collected as follows: (1) For anion and total alkalinity analysis, water was filtered through 0.45-micrometer (µm) pore size syringe filters into a low-density polyethylene (LDPE) bottle rinsed three times with sample water. Samples were stored refrigerated until analysis. (2) Two aliquots were collected for major and trace cation analysis: one unfiltered for total cation concentrations and another filtered through 0.45-m syringe filters for dissolved cation concentrations. For six samples, cation aliquots were filtered using 0.45-µm capsule filters, instead of syringe filters, as noted in Table 2. Samples were collected in nitric acid-washed, LDPE bottles rinsed three times with sample water, then preserved with ultrapure grade nitric acid and stored at room temperature until analysis. (3) For dissolved iron speciation analysis, water was filtered through 0.45-µm syringe filters into a hydrochloric acid-washed, opaque, high-density polyethylene (HDPE) bottle rinsed three times with sample water. Samples were preserved with trace metal grade hydrochloric acid and stored refrigerated until analysis. (4) For dissolved organic carbon analysis, water was filtered through 0.45-µm syringe filters into two replicate 40-mL amber glass vials rinsed three times with sample water. Samples were stored refrigerated and express shipped on ice to the laboratory. (5) For stable water oxygen and hydrogen isotope analysis, water was collected unfiltered in a glass vial with no headspace and sealed with a polycone-lined cap. Samples were stored at room temperature until analysis. (6) For tritium analysis, water was collected unfiltered in a HDPE bottle sealed with a polycone-lined cap and stored at room temperature until analysis. (7) For dissolved noble gas analysis, water was collected unfiltered in two replicate 3/8-inch diameter copper tube segments closed with pinch-off clamps. Adequate back-pressure was maintained on the sample line (using valves) to prevent degassing and bubble formation. (8) For sulfur hexafluoride (SF6) analysis, water was collected unfiltered in an amber glass bottle and sealed with a polycone-lined cap using standard procedures detailed at: https://water.usgs.gov/lab/. Care was taken to prevent contact between sampled water and the atmosphere. Field blank water was processed in a manner similar to the samples to test for equipment contamination and/or sample carryover. Field replicates were collected at a rate of approximately one per 15 samples. Sediment Sample Collection: Twelve stream sediment samples were collected by compositing grab samples collected primarily from the streambanks as little sediment was found in the streambed due to high flow. Four ferricrete samples were collected by scraping coatings off boulders in the stream and compositing a representative sample for the site. Samples were stored in sealed plastic sample bags or jars and transported to the USGS Geology, Geophysics, and Geochemistry Science Center in Lakewood, Colorado where they were air dried, gently disaggregated using a mortar and pestle, and sieved to less than 2-millimeter (mm) size fraction. Water Sample Analyses: Anion and Cation Analyses: Anion, alkalinity, and iron speciation analyses were performed at the USGS Redox Chemistry Laboratory in Boulder, CO. Anion concentrations (bromide, chloride, fluoride, sulfate, and nitrate) were determined by ion chromatography using a Dionex DX600 with suppressed electrical conductivity detection (Brinton and others, 1995; Fishman and Pyen, 1979). Analytical errors for these constituents are determined by checks with internal standards and replicate samples and are typically less than 5 percent. Alkalinity was determined by automated titration using standardized sulfuric acid (Barringer and Johnsson, 1996; Fishman and Friedman, 1989). The analytical error in alkalinity concentrations is less than 3 percent. Total dissolved iron, FeII+III, and ferrous iron, FeII, concentrations were determined in samples preserved with hydrochloric acid using a modification of the FerroZine colorimetric method (Gibbs, 1976; Stookey, 1970; To and others, 1999). Concentrations of major and trace cations were determined using a combination of inductively coupled optical emission spectroscopy (ICP-OES) and inductively coupled mass spectrometry (ICP-MS) at SGS (Societe Generale Surveiliance) Laboratories, Canada, under contract with the USGS Geology, Geophysics, and Geochemistry Science Center (GGGSC). The laboratory uses a method derived from USEPA 200.8 and NIOSH 7300 (references listed below). SGS Labs is accredited to the ISO/IEC 17025:2005 and certified to the ISO 9001:2008 standard. The laboratory’s quality control protocol is to insert a reagent blank and a reference sample material with every batch of 20 samples to measure the analytical accuracy. Duplicate samples are analyzed at the end of the sample set to measure analytical variance and sample variance. Duplicate results were determined acceptable by SGS if recovery of analytes was ±15 percent at 5 times the lower limit of determination and the relative standard deviation of duplicate analyses was ≤15 percent. Blind external quality assurance (QA) reference samples from the USGS standard reference sample program (https://bqs.usgs.gov/srs/) were submitted to SGS along with regular samples at a rate of approximately 10 percent. Dissolved Organic Carbon Analysis: Dissolved organic carbon was measured at the USGS Mercury Research Laboratory in Madison, WI using USEPA method 415.3 (Potter and Wimsatt, 2005). Samples were collected on 8/27/2023, received at the lab 8/30/2023, and analyzed 9/6/2023. Stable Water Isotope Analyses: Stable isotope samples were analyzed at the USGS Reston Stable Isotope Laboratory in Reston, VA. Samples were measured for delta 2H using a hydrogen equilibration technique described in Coplen and others (1991) and Revesz and Coplen (2008a). Samples were measured for delta 18O using the CO2 equilibration technique of Epstein and Mayeda (1953), which has been automated (Revesz and Coplen, 2008b). Oxygen and hydrogen isotopic results are reported in permil relative to Vienna Standard Mean Ocean Water (VSMOW) and normalized (Coplen, 1994) on scales such that the oxygen and hydrogen isotopic values of Standard Light Antarctic Precipitation (SLAP) are -55.5 permil and -428 permil, respectively. The 1-sigma uncertainties of oxygen and hydrogen isotopic results are 0.1 permil and 1 permil, respectively. Tritium Analysis: Tritium analyses were performed at the USGS Menlo Park Tritium Laboratory in Menlo Park, CA by electrolytic enrichment and liquid scintillation counting as detailed in Thatcher and others (1977) and McCurdy and others (2008). Noble Gas Analyses: Noble gas samples were analyzed at the USGS Noble Gas Laboratory in Lakewood, CO for helium (He), neon (Ne), argon (Ar), krypton (Kr), and xenon (Xe) concentrations and for 3He/4He, 20Ne/22Ne, 40Ar/36Ar, 86Kr/84Kr, and 130Xe/132Xe isotopic ratios by cryogenic gas separation and mass spectroscopy methods as detailed in Hunt (2015). Sulfur Hexaflouride Analysis: Sulfur hexafluoride analyses were performed at the USGS Groundwater Dating Laboratory in Reston, VA using a purge and trap gas chromatography procedure with an electron capture detector as detailed at: https://water.usgs.gov/lab/sf6/lab/analytical_procedures/. Analytical precision is about 20 percent (%) at the detection limit of 0.01 femtomoles per kilogram (fmol/kg) and about 3% or better at concentrations >0.2 fmol/kg. Sediment Sample Analyses: Total elemental analyses of solid phase samples were performed by SGS Laboratories, Canada (SGS), under contract with the USGS GGGSC. Representative subsamples were ground to pass through a 0.105-millimeter sieve in USGS GGGSC laboratories and then submitted to SGS. SGS Labs is accredited to the ISO/IEC 17025:2005 and certified to the ISO 9001:2008 standard. The laboratory’s quality control protocol is to insert a reagent blank and a reference sample material with every batch of 20 samples to measure the analytical accuracy. Duplicate samples are analyzed at the end of the sample set to measure analytical variance and sample variance. Blind external quality assurance (QA) reference samples were submitted to the contract lab along with regular samples at a rate of approximately 10 percent. One laboratory replicate (split after sample was dried and disaggregated) was submitted. ICP-49 (Multi-element Concentrations by Four Acid Digestion): Samples were subjected to SGS standardized four-acid (hydrochloric, nitric, perchloric, and hydrofluoric acids) digestion procedure. The solutions of the digests were analyzed by inductively coupled plasma optical emission spectroscopy (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS) using the same procedures as described above for water sample cation analyses. Elements reported by ICP-OES are aluminum (Al), barium (Ba), calcium (Ca), chromium (Cr), copper (Cu), iron (Fe), potassium (K), magnesium (Mg), manganese (Mn), sodium (Na), nickel (Ni), phosphorus (P), sulfur (S), strontium (Sr), titanium (Ti), vanadium (V), and zinc (Zn). All other elements are reported by ICP-MS. Results were determined acceptable by SGS if recovery of analytes was ±15 percent at 5 times the lower limit of determination and the relative standard deviation of duplicate analyses was ≤15 percent. Four-acid digestions are considered near-total but do not completely dissolve some recalcitrant minerals such as barite, chromite, and zircon. Elements that often do not perform well by this method (chromium, hafnium, lutetium, selenium, terbium, yttrium, ytterbium, and zirconium) are reported herein as “informational only”. This is indicated by an ‘I’ after the element symbol in the attribute name (e.g., Cr_I_ICP49_ppm) in Table 7. Barium is not labeled as “informational only”, but ICP-49 analyses for barium may not be quantitative in some samples with substantial amounts of the mineral barite. ICP-61 (Multi-element Concentrations by Sodium Peroxide Fusion): Weighed samples were digested and fused in glassy carbon crucibles using sodium peroxide (Na2O2), and the fusion cake was dissolved in dilute nitric acid. The resulting solutions were analyzed by ICP-OES and ICP-MS using the same procedures as described above for water sample cation analyses. Elements reported by ICP-OES are aluminum (Al), barium (Ba), calcium (Ca), chromium (Cr), copper (Cu), iron (Fe), potassium (K), magnesium (Mg), manganese (Mn), sodium (Na), nickel (Ni), phosphorus (P), sulfur (S), strontium (Sr), titanium (Ti), vanadium (V), and zinc (Zn). All other elements are reported by ICP-MS. The fusion is considered a complete dissolution method. Results were determined acceptable by SGS if recovery of analytes was ±15 percent at 5 times the lower limit of determination and the relative standard deviation of duplicate analyses was ≤15 percent. Because few reference materials have certified boron (B) values to reliably characterize the performance, B is reported as “informational only”. Rhenium is reported as “informational only” because there is not yet an established preferred value for Re and there are insufficient data to calculate means for meaningful comparisons. Elements labeled “informational only” are indicated by an ‘I’ after the element symbol in the attribute name (e.g., B_I_ICP61_ppm) in Table 7. Total Carbon: Samples were weighed into tared ceramic crucibles and, using a LECO Carbon/Sulfur analyzer, combusted under a purified oxygen stream in an induction furnace at 1350oC. The Carbon and sulfur components are converted into CO2 and SO2 respectively and measured by infrared cells and the results reported automatically in percent carbon and sulfur. Samples are analyzed against known calibration materials to provide quantitative analysis of the original sample. Results were determined acceptable by SGS if recovery of analytes was ±15 percent at 5 times the lower limit of determination and the relative standard deviation of duplicate analyses was ≤15 percent. Inorganic Carbon: Samples were treated with dilute perchloric acid to convert inorganic carbon to carbon dioxide, which was quantified with an infrared detector. Results were determined acceptable by SGS if recovery of analytes was ±15 percent at 5 times the lower limit of determination and the relative standard deviation of duplicate analyses was ≤15 percent. Total Sulfur: Samples were weighed into tared ceramic crucibles and, using a LECO Carbon/Sulfur analyzer, combusted under a purified oxygen stream in an induction furnace at 1350oC. The Carbon and sulfur components are converted into CO2 and SO2 respectively and measured by infrared cells and the results reported automatically in percent carbon and sulfur. Samples are analyzed against known calibration materials to provide quantitative analysis of the original sample. Results were determined acceptable by SGS if recovery of analytes was ±15 percent at 5 times the lower limit of determination and the relative standard deviation of duplicate analyses was ≤15 percent. Major Element WDXRF: Iron (Fe) concentration was determined for the ferricrete samples by wavelength dispersive x-ray fluorescence spectrometry (WDXRF). The sample is fused with lithium metaborate/lithium tetraborate flux and the resultant glass disk is introduced into the WDXRF and irradiated by an x-ray tube. The method also provides a gravimetric loss on ignition (LOI). When values for major elements exceed the upper reporting limit for ICP-49 or ICP-61 methods, samples can be analyzed by WDXRF to determine major elements. For this study, most samples exceeded the ICP-49 and ICP-61 upper reporting limits for Fe. However, only the ferricrete samples were analyzed using WDXRF. Streamflow estimates and metal loading profiles were obtained as follows: Streamflow and loads: A continuous, instream injection of a sodium bromide (NaBr) tracer was initiated at the head of the study reach on August 22, 2023 and maintained until the afternoon of August 28. Sodium chloride (NaCl) slug additions were conducted at several locations following the procedures described by Runkel and others (2023) and McCleskey and others (2025) (Table 5). Bromide concentrations from the continuous injection were subsequently used to determine streamflow in the upper portion of study reach (EM-0031 through EM-WQ16) using the tracer-dilution method (Kilpatrick and Cobb, 1985; Table 6). Specific conductivity data (Table 4) from the slug additions were used to determine streamflow in the lower portion of the study reach (EM-WQ16 through EM-17096) using the methodology of McCleskey and others (2025). Bromide concentrations at most locations were corrected for mass loss to produce agreement between the flow estimates provided by the continuous injection and the slug addition at EM-WQ16 (Br_used, Table 6). Slug addition streamflow estimates for the two headwater branches (EM-ABL, EM-ABR; Table 5) were scaled down based on the decrease in flow observed at EM-31 (Table 6). Constituent loading profiles were developed following the methods of Kimball and others (2002, 2007) and Runkel and others (2023). Loads were calculated as the product of streamflow and concentration (Table 6). Average concentrations were used for load calculations at EM-0252 and EM-0809, where sequential replicate samples were collected. Calculated loads may be used to identify and rank sources of constituents to the East Mancos River.
