Significant Research Findings:

Report on Newly Developed and Review of Existing
Bioassessment Tools and Biocriteria for Rivers and Streams

in New England

Scientific	States are required by the Clean Water Act to monitor and report on their water

Problem and	resources on a regular basis. However, bioassessment programs can vary widely

Policy Issues	from statc to state. The biological assemblages sampled, the development of

indicators, and the manner of setting biocriteria vary among New England states.
Some states have much more advanced programs than others, and the experiences
of one state can have an influence on the activities of other states. There is
currently no single document that provides sufficient detail on bioassessment tools
and biocriteria used by state programs to determine comparability of programs.
Both states still developing programs and those with well-established programs
could benefit from a central document that allows for a detailed comparison
among states. The purpose of this project was to develop a report that details the
bioassessment programs and biocriteria for rivers and streams in each state in New
England (Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and
Vermont).

Research	For existing bioassessment tools and biocriteria, we contacted New England states

Approach	to obtain relevant materials describing in detail current bioassessment efforts. As

part of this project, we worked closely with the New Hampshire Department of
Environmental Services (NHDES) to develop a macroinvertebrate bioassessment
tool. The details of this tool and of other methods used by New Hampshire are
included in the document. The features of each state's program are detailed in a
separate chapter, with a summary chapter at the end.

Results and	The result is a report with detailed information on sampling approaches, sample

Impact	collection methods, laboratory processing methods, bioassessment tools, and site

assessment approaches for rivers and streams in New England. This report
provides a central resource to compare stream and river bioassessment programs
across New England states. The report provides valuable information for EPA
program offices and states on the comparability of data and methods among state
programs and on the manner in which Aquatic Life Use support is evaluated in
each state. This report serves as a resource for states, tribes, and municipalities
both within New England and beyond to provide detailed information on methods
for biological assessment, as well as on approaches to identifying reference

condition, evaluating biological data, and setting biocriteria. This report will help
improve the quality and consistency in bioassessment and biocriteria programs.
The primary product of this project is a report entitled, "A Review of Biological
Assessment Tools and Biocriteria in New England States". The final report is
being provided to state and regional biologists, as well as to the Office of Water
and the Office of Environmental Information. The report is also being made
available for download from a link on the division web page:

NERL/EERD research staff are the technical and project leads for this research.
Sobran, Inc. was contracted to assist with collection and summarization of
information, including technical writing. NHDES was directly involved in
development of the New Hampshire macroinvertebrate bioassessment tool.
Representatives from each New England state provided information and
performed technical reviews of individual chapters, and Region 1 and the Office
of Environmental Information personnel provided reviews of the draft document
to evaluate and ensure usefulness.
