These data consists of three related tables describing in-situ field conditions including pesticide concentration, water quality, and post-treatment survival of crayfish associated with the application of a pesticide to a stormwater retention pond and burrows to suppress or eradicate an invasive crayfish species, Procambarus clarkii, in support of high-priority research developing control methods to mitigate impacts of invasive crayfish within the Great Lakes Basin. Effectiveness of the treatment was accessed using an in-situ bioassay and by measuring pesticide concentrations in water, sediment, and caged crayfish. Water quality data, including temperature, pH, specific conductance, dissolved oxygen, alkalinity,...
This data release includes sampling location data; field-collected stream attribute data; laboratory-analyzed chemistry concentrations (total mercury, methyl mercury) and isotopic composition (total mercury, carbon, and nitrogen) for stream biota (seston, periphyton, benthic insects, emerging adult insects, riparian spiders, and fish); density, body length, and taxonomic information for benthic insects; and density, biomass, and taxonomic information for emerging adult aquatic insects for biota sampled from stream reaches up and downstream of an historical mercury mine site. Sampling took place during summer low-flow conditions in 2015 and 2016. Stream reaches were located on USFS land near the Cinnabar Mine Site...
These data are comprised of measurements of elements (e.g., uranium, cobalt, nickel, copper, zinc, cadmium, lead, etc.), major anions (chloride, nitrite+nitrate as nitrogen, sulfate, etc.), dissolved organic carbon, and general water quality characteristics in Canyon Mine containment pond water, sediment, vegetaiton and invertebrate samples collected in calendar year 2017.
Stream water chemistry and benthic macroinvertebrate data collected in the North Fork of Clear Creek and Clear Creek, CO, USA before and after the diversion and treatment of acid mine drainage by a high-density sludge lime process water treatment plant. Stream water chemistry and benthic macroinvertebrate samples were collected from November 2011 through October 2019 at 6 sites located above and below the North Clear Creek Water Treatment Plant (NCCWTP). The NCCWTP became fully operational in September 2017. Measured water chemistry included pH, conductivity, alkalinity, ferrous iron, total and dissolved concentrations of metals and major geochemical cations, and dissolved organic carbon. Replicate (n=5) benthic...
Biological endpoints for three focal test species [Daphnia magna (mortality), Psuedacris maculata (mortality, growth, and development), and Lemna gibba (growth)] in response to exposure to reconstituted or field-collected water under laboratory conditions. Field-collected waters were collected from wetlands within the Prairie Pothole Region (PPR) of the United States. Reconstituted water was mixed to mimic some chemistry of surface water from brine contaminated PPR wetlands. Also included are water quality and chemical concentration data from all assays.
An inventory (enumeration and taxonomic identification) of diet items consumed by wild-caught black carp, based on the examination of gut contents from fish that were collected in the lower Mississippi River drainage of the U.S.
The data represent counts and presence of stream-dwelling aquatic macroinvertebrate communities in nine watersheds within the non-connected stormwater region in Kansas City, Missouri. Samples were collected from 3 stream habitats (coarse substrate in cobble riffles, depositional non-flow habitat in pools, and rootmats along shoreline areas). Macroinvertebrate organisms were enumerated and identified to the lowest practical taxonomic unit.
These data consist of three related tables describing test conditions including pesticide concentration, water quality, and post-treatment survival of crayfish associated with laboratory studies conducted to determine 24-hr acute lethal concentrations of two pesticides containing pyrethrin or cypermethrin for two crayfish species, Procambarus clarkii and Faxonius virilis. Tests investigated whether two nominal temperatures (10 and 22 °C) and total suspended solids in water affected pesticide toxicity. Laboratory data will be used to design field treatments for open-water populations of invasive P. clarkii. Water quality monitoring during testing followed standard testing protocols and included temperature, pH, specific...
This data release includes sampling location data, field-collected water chemistry data, cation and anion concentration data for water and tissues of submerged aquatic vegetation, aquatic insect larvae, adult aquatic insects and riparian spiders from 35 first- and second-order sub-alpine streams that ranged over several orders of magnitude in metal concentrations but were similar in elevation, geology, and stream morphology. Sampling was completed in late summer, after snowmelt runoff was complete and as the streams approached baseflow conditions.
Data were collected associated with the application of a pesticide to a stormwater retention pond and burrows to suppress or eradicate an invasive crayfish species, Procambarus clarkii, in support of high-priority research developing control methods to mitigate impacts of invasive crayfish within the Great Lakes Basin. Effectiveness of the treatment was accessed using an in-situ bioassay and by measuring pesticide concentrations in water, sediment, and caged crayfish. Water quality data, including temperature, pH, specific conductance, dissolved oxygen, alkalinity, hardness, ammonia, and turbidity, in stormwater ponds was collected to evaluate whether environmental conditions may impact treatment effectiveness and...
