Evaluation of the Aquatic Benthic Macroinvertebrates Communities in Blackbird Creek, Jackfish Bay Area in Recovery, Lake Superior, 2011
Author: Ken Deacon
Publisher:
ISBN:
Category : Aquatic invertebrates
Languages : en
Pages : 24
Book Description
Blackbird Creek conveys effluent for 14km from the Terrace Bay pulp mill to Jackfish Bay on Lake Superior, and is part of the Jackfish Bay Area in Recovery. Environmental quality was considered downgraded as a result of discharge from the mill through Blackbird Creek. The Bay was designated an Area of Concern in 1987 (North Shore of Lake Superior Remedial Action Plans 2008) based on restricted fish consumption ; degraded fish and invertebrate populations, loss of fish habitat and degraded aesthetics.--from page 2.

The Benthic Macroinvertebrate Survey of Butternut Creek, Otsego County, New York

Languages : en
Pages : 134
Book Description
A benthic macroinvertebrate survey was conducted on the Butternut Creek, Otsego County, New York. Samples were collected from 18 sites between Basswood Pond and the confluence of Butternut Creek and the Unadilla River from 1 July 2002 to 15 July 2002. Assessments of physical habitat (PHA), family biotic index (FBI), percent model affinity (PMA), and percent Ephemeroptera, Plecoptera and Trichoptera (%EPT) were made at each site. Mean assessment results indicate that the habitat and water quality of Butternut Creek is in good condition. PHA results of 94.17 (+/- 19.42) indicate optimal habitat. Percent EPT values of 50.56 (+/- 20.98) are in the non-impacted range. FBI data averages 4.26 (+/- 1.16) revealing a non-impacted condition. A PMA of 62.61% (+/- 13.20) places the water quality in the slightly impacted range. The benthic community at each site was broken down according to functional feeding group (FFG). A significant decline in shredder populations was found as sampling proceeded down the course of the stream. No relationship was found between location on the stream and PHA. PHA did not have a significant effect on FBI, PMA or %EPT scores at each site.

A Comprehensive Evaluation of Benthic Invertebrate Communities in the Emory River, Watts Bar Reservoir, TN

Publisher:
ISBN:
Category : Benthos
Languages : en
Pages : 128
Book Description
The release of fly ash at the Tennessee Valley Authority (TVA) Kingston Fossil Plant (KIF) on 22 December 2008 discharged approximately 4.1 million cubic meters of coal ash into the adjacent aquatic and terrestrial systems. Previous benthic invertebrate investigations conducted by TVA and collaborative researchers concluded that benthic invertebrates in the Emory River were at moderate risk from ash-related constituents, primarily arsenic, in ash-contaminated sediment that remained in the Emory River following extensive dredging efforts. These conclusions were based on the observation of statistically significant reductions in growth and biomass in laboratory toxicity tests with Emory River sediment. Benthic invertebrate community survey results from 2010, however, did not support this conclusion. These previous surveys evaluated benthic invertebrate community data and sediment data across a large spatial scale, providing an "area-wide" interpretation of the relationships between the benthic invertebrate community results to the ash release. In the present research, co-located sediment and benthic invertebrate community samples were collected from nine locations in the Emory River. Community metric results were compared among samples, locations, and previous years and to co-located sediment chemistry and physical sediment properties. Temporal trends were also evaluated over a 5-year period of time at two locations to gauge if an initial impact and/or recovery could be determined. Despite this refined investigation, no trends or significant differences were identified between ash-impacted locations compared to the reference location, and no evidence of an initial impact or subsequent recovery trends were established. Furthermore, no significant relationships could be established between benthic invertebrate community metrics and sediment chemistry results. This information is important for the informed monitoring, remediation, and damage assessment of the benthic invertebrate community at the Kingston Ash Recovery site. This research also increases our knowledge of benthic invertebrate tolerance to metal mixtures in sediment of natural systems.

Book Description
North American and European governments have adopted national programs for environmental monitoring and assessment that include the use of aquatic biota. These programs will use a variety of indicators of environmental health; benthic macroinvertebrates are one of the most promising of them. The chapters in this book deal with the many different approaches available for using benthic macroinvertebrates in biological monitoring programs.

Benthic Macroinvertebrates of Selected Aquatic Habitats of the Lower Mississippi River

Book Description
This report describes benthic macroinvertebrate composition and distribution in four aquatic habitat types within a 60-mile reach of the Lower Mississippi River. The macroinvertebrate biotas of the four habitat types, dike fields (three), a natural band, a secondary channel, and an abandoned channel, were studied over one high flow (flood stage), two moderate, and two low flow periods between April 1979 and September 1980. The biotas present in the natural bank, secondary channel, and abandoned channel showed only minor changes in composition over the various flow regimes. Unlike the other habitats, the dike fields showed large changes in biotic composition, which correlated with changes in river stage and resultant alterations in current and substrate.
