Summary

This directory provides analytical results for wastewater compounds, steroid hormones, sterols, and bisphenol A, and pharmaceuticals in water and wastewater compounds, steroid hormones, sterols, and bisphenol A, pharmaceuticals, and antidepressants in bottom-sediment samples collected during 2013. In addition, a comparison of data obtained for compounds determined by pharmaceutical methods 8244 and 2440 is provided. Data provided are as reported by the laboratory, unless otherwise noted, and listed by sample.

Summary

This directory provides analytical results for wastewater compounds, steroid hormones, sterols, and bisphenol A, and pharmaceuticals in water and wastewater compounds, steroid hormones, sterols, and bisphenol A, pharmaceuticals, and antidepressants in bottom-sediment samples collected during 2013. In addition, a comparison of data obtained for compounds determined by pharmaceutical methods 8244 and 2440 is provided. Data provided are as reported by the laboratory, unless otherwise noted, and listed by sample. "2013Data_by_Result.xlsx" provides all environmental data included in "2013WaterData" and "2013SedimentData", listed by compound. Discussion of number of detections does not include results that were 'v' or 'Cf' coded (potentially affected by lab or field blank contamination). Although it is ultimately up to the data analyst how to use the data, for the purposes of this report, results determined to be affected by contamination were treated as non-detects. Use of the data provided herein should proceed only after the quality assurance data have been reviewed and taken into consideration.

Only a subset of samples were analyzed using both pharmaceutical methods 8244 and 2440 in unfiltered and filtered water, respectively. More pharmaceuticals were detected using the filtered method (schedule 2440) than using the unfiltered method (research method 8244). Sixty percent of the compounds analyzed were either detected by both methods or not detected by either method. The relative percent difference between detected concentrations of any given pharmaceutical using both analytical methods was calculated by dividing the absolute difference in concentrations between the two methods by the mean concentration from the two methods and multiplying by 100. Relative percent difference between detected concentrations of any given pharmaceutical using both analytical methods ranged from 1 to 189 for all samples.

In unfiltered water samples, 55 of the 69 wastewater compounds analyzed with laboratory schedule 4433 were detected in at least one sample with concentrations ranging from 0.002 to 13.5 micrograms per liter (μg/L). Eleven of the 20 compounds (steroid hormones, sterols, and bisphenol A) analyzed by laboratory schedule 4434 were detected in at least one unfiltered water sample with concentrations ranging from 0.16 to 14,900 nanograms per liter (ng/L). Thirty-three of the 48 pharmaceuticals analyzed by research method 8244 were detected in at least one unfiltered water sample with concentrations ranging from 0.006 to 0.827 μg/L. Eighty-two of the 110 pharmaceuticals analyzed by laboratory schedule 2440 were detected in at least one filtered water sample with concentrations ranging from 0.14 to 27,900 ng/L.

In bottom-sediment samples, 38 of the 57 wastewater compounds analyzed by laboratory schedule 5433 were detected in at least one sample with concentrations ranging from 1 to 26,200 micrograms per kilogram (μg/kg). Thirteen of the 20 compounds (steroid hormones, sterols, and bisphenol A) analyzed by research method 6434 were detected in at least one sample with concentrations ranging from 0.04 to 11,400 μg/kg. Eighteen of the 20 human-use pharmaceuticals analyzed by research method 9008 were detected in at least one sample with concentrations ranging from 0.02 to 11.2 μg/kg. Five of the 11 antidepressants analyzed by research method 9008 were detected in at least one sample with concentrations ranging from 0.01 to 10.3 μg/kg.
