Tasked by the Clean Water Act to restore and maintain the integrity
of their waters, state and local governments must develop systems
for assessing the health of the streams within their borders. They
quickly find that one size does not fit all when it comes to
sampling. Rapid Bioassessment of Stream Health examines the
sampling techniques, laboratory methods, and data analysis
necessary to create a protocol for analyzing the health of streams,
using rapid bioassessment techniques. The editors explore how to
determine reference streams in each ecoregion and subecoregion with
specific indices of health. They provide field methods for
monitoring and sampling invertebrates and laboratory methods for
subsampling. The work focuses on the application of the EPA's Rapid
Bioassessment Protocol (RBP) but suggests various techniques that
can be used to improve sampling protocols and quality control,
where necessary. It also includes general listings of health
classifications, appendices of more than 300 streams that have been
sampled, and a GIS method for designating the reference condition
for purposes of comparison in each ecological unit. Although the
EPA's RBP Manual is considered to be the standard of information on
the types of metrics that can be used, this book explores, from a
state regulatory standpoint, the practical development of such a
system to begin compliance with critical sections of the Clean
Water Act. A compendium of information about prioritizing those
streams and small rivers requiring analysis, this book contains
guidelines on the assessment of streams in a particular ecoregion
and sampling streams that are at least impaired as points of
comparison. It supplies guidance for the production of other rapid
bioassessment tools customized to various ecoregions and
subecoregions.
