Emerging organic contaminants (EOCs) in surface water sources in the Susquehanna River Basin Public

The widespread occurrence of emerging organic contaminants (EOCs) in aquatic environments is of concern due to know ecotoxicological and potential human health impacts. Given the temporal variability in EOC concentration and the associated impacts on water quality, understanding the dominant drivers of temporal variability of EOCs in surface water sources is essential. In this study, we evaluated the spatial and temporal variability of 20 EOCs in three riverine and reservoir drinking water sources in the Susquehanna River Basin. Sampling techniques employed permitted for the characterization of the influence of seasonal and hydrologic drivers in concentration of EOCs.

Abstract/Description of research:

The widespread occurrence of emerging organic contaminants (EOCs) in aquatic environments is of concern due to know ecotoxicological and potential human health impacts. Given the temporal variability in EOC concentration and the associated impacts on water quality, understanding the dominant drivers of temporal variability of EOCs in surface water sources is essential. In this study, we evaluated the spatial and temporal variability of 20 EOCs in three riverine and reservoir drinking water sources in the Susquehanna River Basin. Sampling techniques employed permitted for the characterization of the influence of seasonal and hydrologic drivers in concentration of EOCs.

Date of data collection (single date, range, approximate date)

Samples assessing seasonal influence in EOC concentration were collected between April 2016-December 2017 while samples assessing influence of hydrologic drivers in concentration were collected between January-June 2018

Information about funding sources that supported the collection of the data

DATA & FILE OVERVIEW

File List

  • A. Filename: Emerging organic contaminants (EOCs) in surface water sources in the Susquehanna River Basin
  • B. Short description:
    The dataset is divided in sheets. The first sheet "Description of Sites" provides a summary of description of the study sites where samples were collected. Actual locations are not included for confidentiality reasons. The second sheet "Seasonal Data" provides raw data collected from all the six study sites grouped on a seasonal basis.The remaining three sheets summarize the data that was collected at site E to assess the influence of hydrologic conditions on concentrations of EOCs. Data is summarized in its raw form and also corresponding to discharge/flow rate at the time of sampling as well as values for water quality parametrs such as pH, dissolved oxygen and temperature.

METHODOLOGICAL INFORMATION

Description of methods used for collection/generation of data:

  • All samples were collected and handled following EPA method 1694 (USEPA, 2007 Method 1694: Pharmaceuticals and personal care products in water, soil, sediment and biosolids by HPLC/MS/MS. US EPA Office of Water and Office of Science and Technology. EPA-821-R-08-002. Available at: https://www.epa.gov/sites/production/files/2015-10/documents/method16942007.pdf)

Methods for processing the data:

  • Some water samples were filtered through a 0.22 um polyethersulfone (PES) syringe filter after which samples were concentrated from a 500 uL volume to 20 ul volume using an inline concentrator column Hypersil Gold aQ 20x2.1 mm 12um (ThermoFisher, Sunnyvale, CA) then injected onto a 100 x 2.1mm 3um Hypersil Gold analytical column. Data presented have been censored using blanks. All concentrations that were less than the method detection limits (MDL) have been represented as <MDL. Concentrations or values of the analytes measured between the LOD and the limit of quantification (LOQ) were reported as one half of the LOQ.

Instrument- or software-specific information needed to interpret the data

  • The water samples were analyzed and quantified using a high-resolution accurate mass (HRAM) Q Exactive Orbitrap mass spectrometer (ThermoFisher Scientific, Bremen, Germany), interfaced to a chromatography system through a heated electrospray injection (HESI) source. More details on the methodology and high-performance liquid chromatography (HPLC) and mass spectrometer are summarized in: Kibuye, F.A., H.E. Gall, K.R. Elkin, B. Ayers, T.L. Veith, M. Miller, S. Jacob, K.R. Hayden, J.E. Watson, and H.A. Elliott. 2019. Fate of pharmaceuticals in a spray-irrigation system: From wastewater to groundwater. Science of the Total Environment, 654: 197-208. DOI: 10.1016/j.scitotenv.2018.10.442

  • Insturment calibration information are summarized in: Kibuye, F.A., H.E. Gall, K.R. Elkin, B. Ayers, T.L. Veith, M. Miller, S. Jacob, K.R. Hayden, J.E. Watson, and H.A. Elliott. 2019.

Environmental/experimental conditions:

  • For seasonality assessment, source water samples were collected between April 2016-December 2017. A spatially distributed sampling technique was implemented whereby grab water samples were collected at monthly and bimonthly scales from all six sites and samples from each set of sources (riverine and reservoir) were collected on the same day. Samples were then grouped by sampling month to reflect sampling seasons (Summer, Fall, Winter and Spring) For the assessment of hydologic drivers, samples were obtained between January-June 2018. An automated ISCO 3700 sampler fitted with twenty-four 350 mL glass bottles was programmed to collect stream water samples at Site E at sub-daily time steps varying between 3 and 12 hours depending on the flowrate at the time sampling commenced. Sampling dates and times were determined using real-time United States Geological Survey (USGS) streamflow data from a USGS station located about 10 km upstream from the sampling site. A Campbell Scientific Inc. CR850 datalogger equipped with water level, temperature, dissolved oxygen, and pH sensors was deployed and programmed to scan each sensor every second and store measured averages every 60 min. Water level measurements were correlated with reported USGS discharge data at the nearest monitoring station (R2=0.9). Samples assessing concentrations during baseflow conditions were collected following a period of a short dry spell of no recorded precipitation (rainfall or snowfall) for at least 3 days prior to the sampling date, as the average time between precipitation events in PA is 3 days. Post-storm samples were collected during high-flow events constituting the upper 20th percentile of the full flow regime.

Describe any quality-assurance procedures performed on the data:

  • All samples were preserved on ice during transportation to laboratories for processing and analysis and stored at 4 degree Celsius before processing within 48 h of collection. Data presented have been censored using field, travel and instrument blanks.

People involved with sample collection, processing, analysis and/or submission:

  • Individuals involved in sample collection include:Jeremy Resseguie, Scott Sharp, John Prawzdik, Mike Barger, Ryan Troutman, Dave Richie, Scott Roads, Richard Bitting, and Terry Patrick of the Pennsylvania American Water Company for their help and support in making this research possible. Faith Kibuye, Dr. Heather Gall, Dr. Odette Mina,and Jeremy Harper from Penn State.Samples were analysed by Dr. Kyle Elkin of the USDA-ARS Pasture Systems and Watershed Management Research Unit.
