The other conclusion reached (usually by another set of researchers)
is that the reason for lack of measurable response was that the
program targeted the wrong source(s) of pollution. One that I
recall was in upstate NY (I think), and concluded that while the
chosen BMP's were highly effective in controlling barnyard runoff
etc., the program failed to materially affect downstream water
quality because the real source was something else - manure spreading
practices, or something like that.
I'd sure like to find a source of information where a) they targeted
the right source, b) they got enough participation to count, and c)
they actually measured a beneficial response in terms of downstream
water quality.
I'm equally interested in hearing the opposite, where either lack of
sufficient participation or incorrect targeting produced no
measurable benefit. Ann
