2.2. North America Treatment Wetland Database
(NADB)
Information on the effects of wetlands on water
quality and the effects of these wastewaters on
wetland biota have been collected at many operational
treatment wetlands. This information was
widely scattered in scientific journal articles, monitoring
reports to agencies, consultant reports,
and private databases. A framework to record
and update this expanding knowledge was necessary
to make information available to engineers
and scientists nationwide to eliminate duplication
of effort and to continue to refine the empirical
design equations now in use.
During the period 1991–1993, the NADB was
used to catalog information from 206 natural and
constructed treatment wetlands (Knight et al.,
1993). The NADB has been widely distributed to
the engineering, scientific, and regulatory communities.
The electronic files are available from the
EPA (the contact is Don Brown in Cincinnati,
OH; tel.: 1-513-569-7630). Version 2.0 of the
NADB includes additional information from
treatment wetlands, including the data summarized
in this paper from livestock wastewater
