We need some assistance on deciding what levels of contaminants are acceptable for developments on potentially contaminated land. This is from a human health point of view and will obviously depend on the precise end use, eg residential with or without gardens, commercial etc.
The guidelines from environmental health officers are that, where they are available use the SGVs, soil guideline values. Where thes do not exist, do not use ICRCL values and Dutch Standards do not apply to UK.
Their requirements are that where SGVs are not available site specific values should be derived in accordance with CLR9.
At the moment there are several govenment funded working groups that are having trouble developing additional SGVs. Some values were due to be issued but were withheld because the values were below limit of detection of most labs or below natural background levels.
Many small developments do not have the budget to run into determining site specific values. If government funded groups cannot come up with such parameters, how should a small developer be expected to succeed?
I'm sure that somewhere out there, such work has been done on large projects where, what could be regarded as 'soil specific' values have been determined which could be used as a generic screening value.
Any thoughts? Any help?
