Sediment samples and samples for water-toxicity testing were collected during 2014 from several streams in San Antonio, Texas known locally as the Westside creeks (Alazán, Apache, Martínez, and San Pedro Creeks) and from the San Antonio River. Samples were collected once during base-flow and again after periods of storm-water runoff (post-storm conditions) to determine baseline sediment- and water-quality conditions. Streambed-sediment samples were analyzed for selected constituents, including trace elements and organic contaminants such as pesticides, polychlorinated biphenyls (PCBs), brominated flame retardants, and polycyclic aromatic hydrocarbons (PAHs).

This data release contains bioassay data from sediment toxicity tests conducted by the USGS Columbia Environmental Research Center (CERC) with 66 sediment samples collected from in and around the Upper Columbia River in the fall of 2013. Toxicity testing was conducted from fall 2013 through summer 2014 with the amphipod, Hyalella azteca, the midge Chironomus dilutus, and the mussel Lampsilis siliquoidea. Short-term toxicity endpoints (10-28 d) included survival, weight, and biomass of all test organisms. Long-term tests with amphipods (42 d) and midges (about 50 d) included reproduction endpoint. These data are intended to be used to characterize concentration-response relationships between metals concentrations...

This dataset contains the results of a laboratory chronic bioassay with 6-week-old juvenile mussels (Fatmucket, Lampsilis siliquoidea) in a 28-day zinc exposure (120 and 240 micrograms zinc per liter) with endpoints of survival and growth (biomass and length) following standard ASTM methods. Surviving mussels were transferred from the control and treatment groups into a culture pond and their survival and growth were monitored for 56 days. In this data release we report individual biological, chemical, and water quality measurements from the laboratory toxicity test exposure and pond grow-out period.
This dataset characterizes sensitivity of fathead minnow and a unionid mussel to elevated major ions in produced water from oil and gas extraction process.

The responses (survival, growth, and/or reproduction) of test organisms in six concentrations of toxicants in acute and chronic tests. Chemical and water quality parameters were measured for quality assurance and quality control purposes.
Understanding the effects of fungicides on non-target organisms at realistic concentrations and exposure durations is vital for determining potential impacts on aquatic ecosystems. Environmental concentrations of the fungicide azoxystrobin have been reported up to 4.6µg/L in the United States and 30 µg/L in Europe. The objective of the present study was to evaluate the chronic toxicity of azoxystrobin in water-only exposures with an amphipod (Hyalella azteca; 42-d exposure), a midge (Chironomus dilutus; 50-d exposure), a cladoceran (Ceriodaphnia dubia; 7-d exposure), and a unionid mussel (Lampsilis siliquoidea; 28-d exposure) at environmentally relevant concentrations. The potential photo-enhanced toxicity of azoxystrobin...
This data release contains chemistry and toxicity data from sediment toxicity tests conducted by the USGS Columbia Environmental Research Center (CERC) with 66 sediment samples collected from in and around the Upper Columbia River in the fall of 2013.

Short-term toxicity endpoints (10-28 d) included survival, weight, and biomass of all test organisms. Long-term tests with amphipods (42 d) and midges (about 50 d) included reproduction endpoint. Sediments were analyzed for physical and chemical characteristics, including particle size distribution,...
The data release includes data from four studies: (1) toxicity of a permitted effluent, which entered the Deep Fork River (DFR), Oklahoma, USA, to a unionid mussel (Lampsilis siliquoidea) and to 2 standard test species (cladoceran Ceriodaphnia dubia; and fathead minnow Pimephales promelas) in short-term 7-d effluent tests; (2) relative sensitivities of the 3 species to potassium (K), an elevated major ion in the effluent, using 7-d toxicity tests with KCl spiked into a DFR upstream reference water; (3) potential influences of background water characteristics on the acute K toxicity to the mussel (96-h exposures) and cladoceran (48-h exposure) in 4 reconstituted waters that mimicked the hardness and ionic composition...
This dataset provides individual measurements of toxicity and water quality data used to calculate means reported in the associated publication. The objectives of the present study were to (1) refine test conditions for improving mussel survival and growth in a long-term feeding study, (2) evaluate chronic toxicity of NaCl and KCl to fatmucket under traditional test conditions outlined in ASTM (ASTM 2017) and the refined test conditions, and (3) assess the influences of test durations, starting ages of organisms, and the presence of sand substrate on the sensitivity of juvenile fatmucket to NaCl in chronic exposures under refined test conditions. Multiple tests were conducted to determine the chronic toxicity of...

The data consists of the responses (survival, growth, and/or reproduction) of test organisms were determined in six concentrations of toxicants in 7-day toxicity tests or in four different feeding rates in 7-day feeding experiments. Specifically we evaluated the sensitivity of 2 mussel species (Villosa constricta and Lampsilis siliquoidea) and P. promelas and C. dubia using effluents in 7-d exposures. We then refined the method by determining the best feeding rate of algal mixture for 1-, 2-, and 3-wk-old L. siliquoidea in a 7-d feeding experiment, and using derived optimal feeding rates to assess the sensitivity of the 3 ages of juveniles in a 7-d NaCl test. Finally, we conducted an interlaboratory study among...
This data release contains physical and chemical data from an evaluation of metal contaminated sediments and pore water conducted by the USGS Columbia Environmental Research Center (CERC) with 66 sediment samples collected from in and around the Upper Columbia River in the fall of 2013. Sediments were analyzed for physical and chemical characteristics, including particle size distribution, total organic carbon, acid volatile sulfide, slag content, and concentrations of metals in total-recoverable and simultaneously-extracted fractions. Porewaters were separated by centrifugation and by peepers (diffusion samplers) and were analyzed for filterable metals, dissolved organic carbon, and major ions. These data are intended...

The objectives of the present study were to develop methods for propagating western pearlshell (Margaritifera falcata) for laboratory toxicity testing and evaluate acute and chronic toxicity of chromium VI [Cr (VI)] to the pearlshell and a commonly tested mussel (fatmucket, Lampsilis siliquoidea at 20°C or in association with a co-stressor of elevated temperature (27°C), zinc (50 µg Zn/L), or nitrate (35 mg NO3/L). A commonly tested invertebrate (amphipod, Hyalella azteca) was also tested in chronic exposures.

We conducted multiple toxicity tests to (1) evaluate the survival and growth of juvenile mussels (Fatmucket, Lampsilis siliquoidea) in a standard 4-week and a longer-term 12-week exposures following a method refined from the standard method using two common reference toxicants (potassium chloride [KCl] and nickel [Ni]); (2) evaluate reproductive endpoints from reproductive KCl and Ni toxicity tests. Reproductive toxicity tests started with Fatmucket brooding mature glochidia to five concentrations of K and Ni for 6 weeks. Subsamples of glochidia were then removed from the adults to determine (1) the viability of brooded glochidia; (2) the viability of free glochidia in a 24-h additional exposure; and (3) success...

The objective of this study was to evaluate the chronic toxicity of potassium (tested as KCl) to a commonly tested unionid mussel (fatmucket, Lampsilis siliquoidea) at five water hardness levels (25, 50, 100, 200, 300 mg/L as CaCO3) representing most surface waters in the United States. Chronic 28-d potassium chloride toxicity tests were conducted with 3-week-old juvenile fatmucket using six concentrations of potassium in the five base waters of differing hardness using ASTM standard methods. In this data release we report individual survival, mass, and length along with chemical and water quality measurements.
