Characterization of fish and invertebrate communities near superfund sites is used to assess impacts of contaminants on surrounding aquatic systems and monitor effectiveness of clean up efforts.

Ecological Specialists, Inc. 1995. Ecological characterization for the Weldon Spring site remedial action project. Prepared for MK Ferguson,
Ecological Specialists, Inc. 1996. Ecological characterization for the Weldon Spring site remedial action project, option period, Spring 1996. Prepared for MK Ferguson, St. Charles, Missouri. 30pp. 96-012.
MK Ferguson is part of the project management team contracted by the Department of Energy to clean up the Weldon Spring Site, which manufactured TNT and DNT in the 1940’s and uranium feed material in the 1950’s. Several springs occur near the site which could be contaminated by ground water drainage. ESI conducted an ecological characterization (fish, invertebrates, water quality, sediment quality) of background and potentially contaminated springs near the site.
Fish and Macroinvertebrate Analysis, Ohio County, Kentucky,
Ecological Specialists, Inc. 1992. Aquatic survey of the Fort Hartford Mine site, Ohio County, Kentucky. Prepared for EnSafe, Environmental and Safety Designs, Inc., Memphis, Tennessee. 23pp. 92-006.
Ecological Specialists, Inc. 1992. Terrestrial survey of Fort Hartford Mine, Ohio County, Kentucky. Prepared for EnSafe Environmental Safety and Designs, Inc., Memphis, Tennessee. 17pp. 92-006.
EnSafe was conducting a three phased remedial investigation/feasibility study on an old limestone mine used for the storage of solid wastes from a secondary aluminum recovery operation. When wet, the waste emitted ammonia and chlorides into the terrestrial and aquatic systems on and surrounding the site. After mitigative procedures were implemented, ESI was contracted to conduct ecological surveys of the area to determine if surrounding areas were adversely impacted. ESI surveyed terrestrial vegetational on the 800 acre site, and fish and benthic macroinvertebrates in streams next to the site and at off-site control locations. Relevé and Bitterlich sampling methods were used to determine terrestrial plant species composition, relative abundance and community health. Fish density and species composition data were collected using electrofishing and seining. Benthic macroinvertebrate samples were collected using a petite ponar dredge. Reports were prepared describing the present terrestrial and aquatic communities and possible impacts the emitted wastes may have had on these communities.
Fish and Invertebrate Analysis, Holt County, Missouri,
PRC Environmental Management, 1992.
PRC Environmental Management is monitoring the area surrounding a battery reclamation plant for lead contamination. ESI collected fish from streams upstream and downstream of the facility and from a nearby pond for species composition and tissue analysis. PRC set artificial substrate samplers in each stream for invertebrate colonization. ESI's invertebrate laboratory analyzed samples for density and species composition. Using this data, PRC will assess lead plant impacts on the surrounding aquatic communities.
