Bailey's Creek Pilot Study In 2009, the first commercially-produced SediMite pellets were applied to a small test plot of PCB-impacted sediments of Bailey's Creek, a brackish intertidal salt marsh system. Pre- and post-application samples were analyzed for sediment contaminant concentration, carbon content, benthic community, and bioavailable portion of the ...

Dredging was completed in summer 2010 and the benthic community sampling was conducted in December 2010. This study is part of a series which supported an Ecological Risk Assessment for the Kingston site. Benthic invertebrate communities were sampled at transects spread across approximately 20 miles of river that includes both ...
Literature is limited in the realm of aquatic coal combustion residue (CCR) exposures and the potential magnitude of effects on benthic invertebrates. Sediment samples along a spectrum of ash content were used in a tiered toxicity testing approach, and included a combination of 10‐day sediment toxicity acute tests and longer‐term, partial life‐cycle “definitive” ...
Extirpation concentrations of specific conductance were estimated from the presence and absence of benthic invertebrate genera from 2,210 stream samples in West Virginia. ...
The first part of this multiyear effort has been completed and resulted in the development and validation of an integrated collection of tools, thresholds, and a data interpretation framework for assessing sediment contamination impacts on benthic community condition. The State Water Board's narrative sediment quality criteria and assessment framework became effective in 2009, ...
Benthic macroinvertebrates were sampled in the Chaguana river basin in SW Ecuador in March (wet season) and September (dry season) of 2005 and 2006. ...
In response to the recent focus on the bioassessment of lakes and reservoirs, the macroinvertebrate-based Nepal Lake Biotic Index (NLBI) has been developed. Benthic samples were collected from reference and impaired lakes during 2006 and 2009 from two ecological zones: Terai-Siwaliks and Mid-Hills. ...
Benthic macrofauna are used extensively for environmental assessment, but the area sampled and sieve sizes used to capture animals often differ among studies. Here, we sampled 80 sites using 3 different sized sampling areas (0.1, 0.05, 0.0071 m2) and sieved those sediments through each of 2 screen sizes (0.5, 1 mm) to evaluate ...
