Apart from the possibility of herbicides and pesticides, I wouldn't automatically regard nurseries as 'clean'. About 10 years ago I was involved with a complex scheme in Stoke on Trent, which included the relocation of an existing nursery. We peppered the entire site with boreholes and trial pits - this included a 1970's landfill, cricket ground, former football pitch, and landscaped parkland, as well as the nursery.
On receipt of the numerous ICRCL suites of analyses, guess which area of the site appeared the most contaminated???
... and the nursery tenants insisted upon taking their 'topsoil' with them to the new location! Well I suppose it saved on special waste tipping charges.

Dear All
Im new to the list and haven't had a chance to browse it all so please
forgive me if its already been discussed!
As a Borough with limited contamination issues we are looking to try and
get
a lot of remediation done through the planning process. A few years ago
we
sent out work to consultants to identify potentially contaminated sites.
I'm currently filtering this data and have noticed that areas that were
previously used as Nurseries have been identified as potential sites.
I can only assume that this is for the possible use of pesticides and/or
herbicides on these sites. I am currently reviewing a planning app for
a
gentleman that wants to build a swimming pool, a dining room extension
and a
rear garage onto his property. Now this house was on the site of an old
nursery (not sure when closed but possibly post WWII) and obviously any
potential contamination is a concern.
So I went looking on the web for pesticide longevity in the environment
and
came across this site:
http://www.oznet.ksu.edu/library/crpsl2/c707.pdf which is for herbicides
(http://www.oznet.ksu.edu/library/crpsl2/ provides a very extensive
resource
on crops and plant biology and physiology in relation to contaminants
and
other environmental factors; even if it is Kansas specific). Next I
found
http://www.pan-uk.org/pestnews/actives/ddt.htm when I went looking for
information on pesticides (actually a good site if you need
information).
Seems to be that there is the potential for some chemicals to persist in
the
environment for quite some time
I was wondering if anyone out there has experience of herbicide and
pesticide residue problems in the soil or can point me in the direction
of
any information?
Cheers!
