Title:Time series of total and soluble iron and manganese concentrations from Falling Creek Reservoir, Beaverdam Reservoir and Carvins Cove Reservoir in southwestern Virginia, USA from 2014 through 2023
Alternate Identifier:DOI PLACE HOLDER
Abstract:

Depth profiles of total and soluble metals were sampled from 2014-2023 in two drinking-water reservoirs, Falling Creek Reservoir (FCR) and Beaverdam Reservoir (BVR), located in Vinton, Virginia, USA. Only Fe and Mn were analyzed from 2014-2019. The full suite of metals (Li, Na, Mg, Al, Si, K, Ca, Fe, Mn, Cu, Sr, Ba) were analyzed from 2020-2023. Both reservoirs are owned and operated by the Western Virginia Water Authority and are managed as secondary drinking-water sources for the city of Roanoke, VA. The dataset includes metals samples that were collected along a depth profile taken at the deepest site of the reservoir near the dam. Additional samples were collected at a gauged weir located on the primary inflow tributary, as well as at a secondary tributary, to Falling Creek Reservoir. Sampling frequency was approximately weekly during the summer and fall (May - October), approximately fortnightly during the spring (March - April), and approximately monthly during the winter (November - March).

Methods and protocols used in the collection of this data package
Description:

WATER COLUMN SAMPLING: We collected water samples for total and soluble metal concentrations from Falling Creek Reservoir (FCR) and Beaverdam Reservoir (BVR) approximately fortnightly from March-April, weekly from May-October, and monthly from November-February. Water samples were collected at the deepest site of each reservoir using a 4-L Van Dorn sampler (Wildlife Supply Company, Yulee, FL). In FCR, water samples were collected at specified depths ranging from 0.1 m to 9.8 m. Additional water samples were collected from the primary inflow tributary as well as a secondary tributary. In BVR, water samples were collected at specified depths ranging from 0.1 m to 12.0 m. After collection, we poured raw water samples directly from the Van Dorn sampler into sample bottles for total metal analyses and we syringe-filtered water using 0.45 micron nylon filters into bottles for soluble metal analyses. All samples were preserved using trace metal grade nitric acid to pH less than 2.

SAMPLING TIMES: Most sampling occurred between the hours of 9:00 and 15:00. Some sampling occurred outside of these hours, including some overnight sampling; these instances are noted by the actual sampling time within the DateTime column. Samples with no exact sampling time recorded are reported as 12:00 in the DateTime column and flagged with a '1' in the Flag_DateTime column. Samples were collected in the America/New York Eastern Time Zone, which observed daylight savings time from approximately March to November in 2014-2020.

CHEMICAL ANALYSIS: In 2014-2015, samples were analyzed for Fe and Mn using an Inductively Coupled Plasma-Mass Spectrometer (ICP-MS; Thermo Electron X-Series) following APHA Standard Method 3125-B (American Public Health Association et al., 1998). Detection limits for Fe and Mn were 0.0008 mg/L and 0.0005 mg/L, respectively, in 2014 and 0.0012 mg/L and 0.00007 mg/L, respectively, in 2015. In 2016-2019, samples were analyzed for Fe and Mn using an Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) using a Spectro ARCOS SOP (Side-On Plasma interface) instrument using methods similar to EPA 200.7 (EPA, 1994). Detection limits for Fe and Mn were 0.004 mg/L and 0.001 mg/L, respectively. Starting in 2020, samples were analyzed for Li, Na, Mg, Al, Si, K, Ca, Fe, Mn, Cu, Sr, and Ba using an Inductively Coupled Plasma-Mass Spectrometer (ICP-MS; Thermo Electron iCAP-RQ) following APHA Standard Method 3125-B (American Public Health Association et al., 1998). In 2020-2021, minimum reporting levels for Fe and Mn were 0.005 mg/L and 0.0001 mg/L, respectively. In 2023, minimum reporting levels for Fe and Mn are as listed in the MRL document: https://raw.githubusercontent.com/CareyLabVT/Reservoirs/master/Data/DataNotYetUploadedToEDI/Metals_Data/MRL_metals.txt. The minimum reporting levels for Li, Na, Mg, Al, Si, K, Ca, Cu, Sr, and Ba from 2020-2023 are also listed in the MRL document. We used the minimum reporting levels as the lower threshold for data in 2020-2023. Values that were below the minimum detection limit (for 2014-2019) or minimum reporting level (for 2020-2023) were flagged as '3' and set to the value of the minimum detection limit or minimum reporting level. Negative values were flagged as '4' and set to 0 in 2014-2022 and were set to the minimum reporting level in 2023.

Occasionally, unfiltered samples contain particulates. As particulates cannot be analyzed using ICPMS, samples with particulates were first microwave-digested with concentrated trace metal grade nitric acid (modified from EPA 3015a) prior to analysis and are flagged with a '6'. Please see Metals_maintenancelog_2014_2023 for more information about specific samples.

This data package includes 2 data files (Metals_2014_2023.csv), QAQC R script (metals_qaqc.R), maintenance log (Metals_maintenancelog_2014_2023.csv), visual inspection R script (Metals_Inspection_2014_2023.Rmd), sampling sites (site_descriptions.csv). The QAQC script includes functions to process data, remove outliers, and apply the maintenance log to clean the data files included in the package; the visual inspection script provides code for plotting the data files.

Multiple whole-ecosystem experiments have been conducted at Falling Creek Reservoir, including intermittent operation of hypolimnetic oxygenation (HOx) and pulsed epilimnetic mixing (EM) engineering systems. We encourage you to contact the lead author of the data package for more information.

Additional Info

Additional Information:
 

Contributions to the 2022 revision: MES initiated metals sampling at Falling Creek Reservoir and Beaverdam Reservoir in 2014, and at Carvins Cove Reservoir in 2022. CLM served as the point person for data cleaning, analysis and QAQC from fall 2022 to present. CLM scripted the automation of raw data processing into publishable form with assistance from NWH. ABP led field crew and sampling efforts at all three reservoirs in 2022. NWH, BG and GH contributed substantially to preparation and sampling for field campaigns.

Acknowledgments and historical contributions: This data package has been iteratively updated over time and builds on the many historical contributions of co-authors listed in previous revisions. We thank the Western Virginia Water Authority for providing access to these sites, the Reservoir Group for contributing to fieldwork, and Gavin Moore for organizing samples in summer 2022.
