Subject: USEPA handbook on
assessment of constructed/engineered wetlands I was mentioning on phone minutes
ago
The citation
is:--
Strecker, E.W., J.M.
Kersnar, E.D. Driscoll, and R.R. Horner. 1992. The Use of Wetlands for
Controlling Stormwater Pollution. The Terrene Institute.
66pp.
The Terrene Institute
publishes/published some of USEPA’s handbooks!
This is what I had been referring to
as the USEPA’s review handbook though there must be others of latter dates
(depends on funding available to them, I suppose).
I also distinctly recall giving a
photocopy of the whole handbook to John Sheppard during the year before
amalgamation, 1995, at the DVR!
This was a summary/overview of the
performance of constructed (or engineered) wetlands for stormwater treatment all
over the
I recall it also had several graphs
which showed box plot percentiles of size of the constructed wetlands versus the
drainage area they trap in addition to several other
graphs!
VVVVVVIMP: -- It also
emphatically cautions against use of natural wetlands for anthropogenic driven
stormwater pollution and I summarized it in http://lakes.chebucto.org/SWT/treatment.html#intro
I understood Clayton Development’s
consultants utilized a small natural wetland as the outflow of CDS devices they
installed in Portland Hills, alas!!!
I recall discussing them with Rene
Roberge PEng of John Sheppard’s team pursuant to the email she had sent me (see
http://lakes.chebucto.org/WATERSHEDS/COWBAYR/MORRIS/roberge_morris_russell.html)
in 1999!
We both were intensely concerned of
the consultant’s plan although I think Rene lost `regulatory influence’ since
the development engineering function was transferred back to HRM’s P&D unit
(recall for a short while, that function was part of Sheppard’s
team)!
My original handbook I bought is
misplaced at my place and someday I hope to find it as I don’t plan to purchase
another assuming it is still in print!
